2017 Surly Ogre Review: ETs, Molokos, 27.5+, and a braze-on fiesta…

Share Facebook 0 Twitter Pinterest Google+

Following the Troll’s recent revamp, it was only a matter of time before Surly’s 29er all-rounder, the Ogre, underwent a similar transformation. Read on to discover details of its 2017 incarnation and thoughts on its frameset, set up with 27.5+ wheels. Also included are musings on the relative merits of different Plus sizes, depending on the style of your backcountry explorations.

2017 Surly Ogre

In case the title of this post sounds like we’re speaking in tongues… let me explain. Surly’s popular, globe-trotting Troll recently saw a significant revamp. The updated model ushered in clearances for dirt-chomping 26+ tires. Its eyelet-riddled fork added provision for Anything Cages both forward and aft. Its rear spacing introduced Surly’s new Gnot-Boost dropout, compatible with a range of hub standards, both old and new. Last but not least, the Troll’s geometry was rejigged into a rigid specific design, forgoing the option of running a suspension fork in lieu of a larger framebag.

Just a few days ago, Surly announced the 2017 Ogre. It sports a similar slew of updates as the Troll, albeit with 29er wheelset that can now be swapped out for 27.5+ tires, the most popular diameter in the Plus-size fold. Surly have only released the first few details so far. Here’s our take on its changes and an account of our hands-on experience with the frameset, having used it bikepacking, commuting around town, and on local trails. We’ll add a link to a geometry table when it’s available.

First things first. Let’s talk wheels. Being a fan of the Plus size wheel format, I was delighted to see that thanks to a new yoke, the 2017 Ogre now accommodate 27.5+ tires, the wheel size that’s fast becoming the de facto norm. Clearances are on the generous side too. During my test riding, I ran both chunky, 3in WTB Trail Bosses and the slightly narrower Ranger Tough – a great touring option, incidentally – with plenty of room for mud clearance or a buckled wheel.

There are, however, a couple of caveats. For one, you’ll need to run a single chainring or an offset double, like Surly’s OD crankset, to enable sufficient clearances between the chain and tire. Specced with a standard 29 inch wheelset, the 2017 complete Ogre comes with a standard 48x36x26 Shimano LX triple, so it’s an after-market change you’ll have to make.

Given its horizontal dropouts and the lack of an eccentric bottom bracket, running 27.5+ wheels will also lower the bottom bracket height, due to their smaller outside diameter. Although the BB drop is the same on both new and old Ogres (68mm), running a 27.5+ tire will decrease its height by at least 10mm, depending on the tire you’re running – putting it at around 295-300mm mark. Although this sounds significant, the reality was that given my uses for the bike — relatively mellow desert singletrack, dirt road touring, and commuting — pedal strike didn’t prove to be the issue I was expecting. Only on the occasions when I hit rockier trails did I notice the difference. In hindsight, I’d recommend speccing 170mm cranks to make up for some of the shortfall, especially if you’re headed for chunkier terrain and ride with flat pedals.

26+x27.5+x29+?!?

Here at BIKEPACKING.com, we’re big fans of the wide rim and Plus size wheel format, whether it be 35mm rims and 2.8in tires or 40mm+ with 3in rubber. Racing aside, we believe Plus tires are a great choice for exploratory, backcountry touring, especially for those running a rigid setup. They strike a practical balance between full fat and conventional tires. They’re confidence-inspiring offroad. And whilst unable to match the breadth of terrain covered by a fat bike, they’re encourage adventures in places previously overlooked by many bicycle tourers. But there’s a question we’ve often asked: with so many wheel diameters to choose from, which is best for what? Given the ever-shifting landscape of tire widths and wheel sizes — as well as their availability both at home and abroad — here’s our thoughts…

For a world trip, particularly one that includes the African continent, there’s still advantages to running a 26in wheelset. Despite the prevalence of courier agencies, nothing beats the convenience of buying parts locally to keep you on the road – 26in remains the firm favourite of hardware stores the world over. Given the availability of WTB’s Ranger Tough in a 3in width and other options, the new Surly Troll has rekindled our interest in the 26in format. For smaller riders, 26+ wheels offer significantly more clearance between the tire and the seat post than other Plus sizes, allowing space for a larger seatpack. In the case of Surly’s range, the Troll comes in an XS size, unlike the Ogre.

29+ remains a solid choice, especially for taller riders. At 6’1″, it’s my wheel size of choice; smaller riders may run into real estate issues between tires and bags. Run as part of a rigid setup, a 3in 29+ tire is extremely capable off-road. In many ways it rules surpreme across rough terrain, thanks to its ability to roll over the largest of babyheads. Options for long distance, bikepacking-friendly tires are relatively good, including WTB’s Ranger Tough and Maxxis’ Chronicle. In larger cities at least, standard-width 29er tires are globally available, should you need a bail out option for your midfat rim.

Although smaller in diameter than a 29+, 27.5+ still takes the bite out of rocky trails, helps negotiate sandy arroyos, and adds noticeably to rider comfort, without adding excessively to a bike’s weight. Spares tires are that bit lighter to carry too. 27.5+ is a size that will likely work for those of both large and small stature, making it a good choice for couples of differing heights who want run to run compatible wheel sizes. The 27.5+ format is becoming increasingly available globally; in a worst case scenerio, a damaged wheel can be replaced with a 29in wheelset, as the outside diameter is similar. There are more suspension forks available and rear racks with suitable clearances are easier to source. For those heading overseas, a 27.5+ bike is easier to box and or cram into the underbelly of a bus than one with 29+ wheels. Given the ever-increasing range of 27.5+ tires on offer in Europe and the US, many backcountry trips may be best served by this in-betweener size.

The dropouts themselves will be familiar to anyone with experience of the Surly touring lineup. Like its predecessor, the new Ogre can be run with derailleurs or as a singlepeed, along with various cargo-pulling configurations — like a BOB trailer or Surly’s two-wheeled siblings, Bill and Ted. As with the last generation of Ogres, the dropout features a slot for anchoring a Rohloff internal hub. Whilst we applaud Surly for its trademark versatility, it does come at a cost to practicality. In terms of removing the rear wheel and tensioning the chain, it’s certainly not as user-friendly as an eccentric bottom bracket and a Rohloff-specific dropout. Also of note is an increase in the welding surface. I’ve come across a handful of riders on long, demanding trips across South America that have had cracks develop at the junction of the chainstay and older generation dropouts. Hopefully this improvement will address the issue.

Surly Ogre Review, 27.5+

As for its 12mm x 145mm Gnot Boost spacing, there are inevitable pros and cons to the system. One the one hand, it allows the use of either 12 x 142mm thru axle or 12 x 148mm Boost thru axle hubs. By using Surly 10/12 Adapter Washers, as I did, 10 x 135mm bolt on or 135mm QR hubs are compatible too, reassuring in this ever-shifting world of ‘standards’. The downside? It’s not a captive thru-axle design, so you’ll lose out on the inherent stiffness of the system. To run a 27.5+ wheel, you’ll also need to pull the wheel back 12.5mm in the dropout. Surly supplied me with a prototype Monkey Nut that helps position the wheel. It works really well and there’s been no slippage to report. For QR hubs, you’ll need to deftly hook the cassette around the chain, a task that inevitably involves oily fingers. My advice? Go tubeless, so wheel removal rarely becomes an issue. Bear in mind too that Surly recommend lowering the tire pressure so sidewalls don’t rub against the canti-studs. At this point in time – given the quality of disc brakes and the ever decreasing availability of rims with braking surfaces – I’d be happy to lose them altogether. But I’m not going to complain too vocally.

In terms of the frame itself – 4130 cromoly steel, of course – the headtube sees a small but welcome extension, in lieu of a longer, suspension compatible rear fork. As a rider who gravitates towards a fully rigid setup, especially for dirt road touring, I see this as a welcome refinement and a more clear way of differentiating the Surly lineup. The result is a bike built for purpose that features a considerably larger framebag space. The one on my XL test bike is simply enormous, on par with the Jones Plus. If a plush suspension fork is a necessity for your bikepacking adventures, the more trail-orientated Karate Monkey is likely a better fit, or there are plenty of other options on the market.

Surly Ogre 2017 Review

Headtube and seat tube diameters all remain the same — 1 1/8″ non-tapered and 27.2mm respectively — which means parts unearthed in your garage can likely be pressed into service. I’m glad to see Surly have kept the Ogre ‘old fashioned’. When it comes to setting up a touring or commuting bike, there’s nothing more satisfying than recycling old possessions.

Clearances are drawn for 29×2.6in tires – depending on rim choice and tire tread – assuming the ‘legal’ 6mm spacing on either side of the tire is to be maintained. In reality, there’s scope for more; we even managed to squeeze in a 3-inch Knard, albeit with a razor tight clearances at the back. Still, a 2.6in tire, like Schwalbe’s Nobby Nick, on a 35mm rim sounds like a great setup to me.

  • 2017 Surly Ogre Review

As we’ve mentioned, there are eyelets for three water bottles on the frame, complimented by a three-pack mount above and below the downtube. The fork sees provision for up to four bottles/Anything Cages though if you want to run a front rack too, there may be a conflict of interests. I tried it with a Nitto M18 and found room for 4 water bottles by using longer, replacement struts. I also fitted Surly’s excellent 8-Pack rack, which limited me to two Anything Cage mounted behind it. Running a full soft bikepacking bag setup will give you the most options. Having a fork covered in barnacles may not be to everyone’s aesthetic tastes, but it sure is practical.

Taller riders should be aware that sizing on the new Ogre has also seen a change. XL and XXL have now become meshed into one – at 640mm, the XL Ogre’s effective top tube sits squarely between the two older sizes. Seat tube length remains identical to the older generation XL. Beanstalks and Clydesdales may feel a little short-changed. Still, a generous headtube length and an upright stem should ensure even leggy riders can dial in an upright handlebar position to match their saddle height. At the other end of the scale, more petite bikepackers will need to check out the Troll, as there’s no XS frame in Ogre flavor. Elsewhere, sizing remains similar between the two generations, if just a hair longer in the effective top tube lengths.

  • 2017 Surly Ogre Review

As for the ride itself, the Ogre really won us over. A total of four riders spent varying amounts of time riding my test bike. Everyone returned with extremely positive reports. Although the new version is 1cm longer in wheelbase than the legacy frameset – and a touch longer still if running a 27.5+ wheelset – the trail figure is relatively similar between the two generations. Don’t assume that the loss of a suspension compatible frame has turned the Ogre into a staid tourer. It’s quite the opposite. Even with 27.5+ wheels, the Ogre threads through singletrack in an extremely engaging way, while its longer wheelbase adds subtly to its stability under load. Surly’s choice of frame tubing felt well suited to my demands and weight, including multi-day bikepacking, grocery shopping, and kid hauling. In the interests of one bike simplicity, I ended up leaving my Wald 137 basket attached, making it the consummate all-rounder. The 27.5+ wheelset I was running — Ranger Plus tires and Scraper — kicked up to speed nicely on pavement and kept their speed well. I’d consider it better suited to road miles than an equivalent 29+ wheelset and only a little more slovenly than a 29×2.4in tire.

  • Surly-Ogre-Review_27
  • 2017 Surly Ogre Review

Spec-wise, the Ogre’s most notable changes include its new, tubeless-friendly 2.5in ET touring tires, now available in a 29in format. Rims for the production model are a somewhat modest 25mm wide. Given the unlikelihood that I’d choose to run the Ogre with narrow slicks, I’d have far preferred a rim that lies in the 35mm internal diameter ballpark.

The new Ogre also swaps out my all time favorite handlebar, the Jones’ Loop H-Bar, for Surly’s oddball Moloko – a chromo alternative that sports a 34 degree sweep and a 735mm width, as well as two protruding horns that offer a dizzying variety of riding positions or, if need be, impaling options should the advent of the apocalypse present itself. The main observation I’d make is that the forward sweep is greater than the Jones, requiring a shorter stem. Factoring in the longer top tube on the XL I tried, this extended my reach more than I like. If you can look beyond Moloko’s freaky looks and their hefty weight, it’s an interesting option for those who favour a full gamut of hand positions and if necessary, handlebar real estate for a spectrum of electronic gizmos.

Still, whether you are a Moloko fan or not, there’s not doubt that $1700 for the complete bike makes it a compelling build. As a sidenote, I’m glad to see the inclusion of a Shimano drivetrain – if only because Shimano BBs are so much easier to source outside the US – as well as the likes of low maintenance, 10-speed Microshift shifters and my favourite BB7 brakes. There’s one caveat though. As my desire for backcountry exploration has increased and my need to ride quickly has consequently diminished, the Ogre’s 48x36x26 chainrings seem over-geared to me.

For reference, here’s the majority of the 2017 Surly Ogre complete build kit:

  • Accomodates both new and old hub standards, as well as a Rohloff.
  • Riddled with eyelets on the fork and frame, for all your water carrying and rack-mounting needs.

Cons

  • Rims on stock bikes are on the narrow side for running big volume tires.
  • Whilst very versatile, horizontal dropouts are more fiddly to use than vertical ones.
  • Running a 27.5+ wheelset lowers pedal clearance, resulting in potential pedal strikes over chunky terrain.
  • 48/36/26 triple is overgeared for loaded, backcountry explorations (but good for fast touring and commuting).

Wrap Up

Given that we’ve only tried the frameset, this isn’t a comprehensive review of the complete Ogre. But having ridden spent a considerable amount time on a bike set up with 27.5+ wheels, it’s hard not to wax lyrical about it. The new Ogre is fast and fun through singletrack. It’s extremely versatile. And it hits a very inclusive price point. All in all, it’s a very capable all-rounder: I’ve happily commuted on it, hit local trails on my way home, or escaped at the weekend to sleep under the stars.

As for the Ogre’s new build, there’s lots to like and just a couple of quibbles. Given my propensity to stray off-road, I’d have far preferred wider rims to come as standard; 27.5+ possibilities aside, this is a bike that cries out for a 35mm rim and 2.4-2.6in tire. In a similar vein, I’d liked to have seen a standard mtb double rather than a touring triple. It’s not that I have an issue with triples; more that it feels overgeared for the riding I do, while a double offers a touch more chain clearance with larger volume tires.

Whether a rigid specific frame suits you or not is down to personal taste. I certainly see it as a good thing (and if you don’t agree, there are plenty of suspension corrected offerings on the market, like Surly’s Karate Monkey, Advocate’s Hayduke, or Bombtrack’s Beyond +). Given the riding I enjoy most, I’ll gladly forfeit the ability to run a suspension fork in return for more framebag space, especially when running large volume 29er or Plus tires. Speaking of which, the 27.5+ wheel size has really won me over. It adds significantly to comfort, traction, and flotation, while maintaining a more ‘normal’ mountain bike feel on both pavement and trails.

All these factors considered, the new Ogre frameset builds up into one of my favourite touring bikes to date, at a price tag that’s affordable to almost everyone. Technical trails aside, I’d recommend it for almost anything you care to throw at is, from an overnight bikepack to a long, trans-continental odyssey…

Rider’s Background

I’ve been embarking regularly on two-wheeled explorations for the last 18 years. Most recently, I connected the length of the Americas via the road less traveled, and explored Mongolia on a fat bike. Given my love for mountain biking and backcountry touring, my ideal journey fuses the two, keeping to quiet dirt roads and singletrack where possible.

Height: 6’1”
Weight: 165 lbs

    At 6’7″, a true XXL is critical. I understand that it makes very little financial sense for companies to extend their size range that far from the average, but it is a bummer that they ditched the XXL.

  • http://MaxTheCyclist.wordpress.net Max Dilthey

    Great review. I’m more excited for the Ogre than any of the other updated bikes. If Kelley had been in the market now as opposed to a year ago, I have no doubt we would have gone with an Ogre over the Krampus. But, c’est la vie!

  • http://www.offroute.ca Skyler

    Surly is doing very smart things as they tease apart the touring bikes from the mountain bikes in their lineup. I’m really impressed to see them go rigid specific. My experience was that their old suspension correction wasn’t actually compatible with any modern suspension anyway. Great write-up, Cass!

  • http://www.bikepacking.com/ BIKEPACKING.com (Logan)

    Agreed. Their lineup is coming into its own with the latest iterations. A couple of years ago there seemed to be a lot of trailing question marks. Although I would like to see the 27.5+ option. And Krampus/KM specced with a Sus fork. That would really distinguish the rigid specific options.

  • https://anadventurERinmedicine.blog Jake Current

    After a lot of debate, I finally decided to build up one of the new KM frames as a 27.5+ Jones loop trail/dirt road/bikepacker machine, but just found out today that ETA got pushed back to April-May. This new frame seems to tick almost all the same boxes and makes me question which frame would be better..

  • Dan Forsyth

    I love some of Surly’s ideas, and was considering buying a new Karate Monkey. It’s just a shame the prices in the UK are more in pounds than they are in dollars in the US – meaning they look poor value for rigid bikes.

  • Mark Troup

    I am very much not in the market for a new bike right now… but if I was, the Troll, Ogre, and Karate Monkey might be number one, two, and three on my shopping list. I think Surly is just killing it right now.

  • Olly Roberts

    Only a megre 6’4″ here, but I still agree. It’s hard to get a good fitting bike if youre tall.

  • Chris Leydig

    Wow, I wish these were available 2 years ago, I think I have plus-envy. I’m 6’2 and have a lg, 2015 troll – I’ve put a lot into it – I run it 26×3, 27.5×2.3 or 29x40mm, depending (all with dropouts maxed). Even got 2 additional forks for it: one carbon, one 80mm susp. Bikepacking, mtn biking, cross – it does all these things, but I’ve been reeeallly been tempted by the ever-increasing +tire options to trade-up. I keep having to remind myself to love what I ride. I’d appreciate further musings on all the +options in terms of handling/speed/weight since you’ve been able to ride so many of them.

    I’m familiar with the pros for larger rubber in terms of speed/rollover etc, but how would you describe the handling? On a previous bikepacking trip that had some technical climbs, I found my 26+ more suitable than the 29er rigs my buddies were riding. Places they dismounted I found my way through. Not chalking it up to skill, but any merits for riding smaller +tires?

  • Harry Major

    Rememeber that UK prices include big ol’ dump for VAT and US prices are listed tax free

  • Cass Gilbert

    A couple of friends of mine who are similar in height to you found the XL worked well (I run my handlebars and seat post unusually high) but you’re right, it’s a shame to loose the XXL.

  • Cass Gilbert

    Thanks Skyler.

    The Surly Venn diagram of overlapping uses can be really hard to get your head around. Differentiating the models like this makes life a lot clearer and let’s each bike excel at what its primarily being used for. Especially since, as you say, finding suspension forks to fit the ‘touring’ models is often a non-starter.

  • Cass Gilbert

    I haven’t had a chance to ride a Troll with a Plus-size setup. But comparing the ECR to the Ogre in a 27.5+ setup by way of example… the Ogre feels threads considerably more easily through singletrack. It feels a lot livelier. I definitely still see the benefit of 29+ when it comes to big, rocky descents, sandy arroyos etc… But it’s an incremental one, not a game changer. If there was a ‘one size to rule them all’ situation, I think 27.5+ is a great sweet spot for a lot of people and uses.

    All this said, if 27.5+ and 29+ hadn’t come to market, I’d probably still be very happy with my old Troll… I love that bike!

  • Smithhammer

    Don’t forget the ECR – one bike to rule them all. ;-)

  • Lewy

    Did you put much time in on the ET tyres? I am planning on using one on the back of my ECR if the height difference isn’t too drastic.

  • Cass Gilbert

    I didn’t try the complete bike, so no experience with 29×2.5in tires I’m afraid.

  • Stephen Poole

    So Cass, where do you see the pros and cons for + versus fatbikes? I’m hoping to traverse some probably still under construction routes in Ladakh and Zanskar later this year and debating whether to take 26, 26+ (if these would clear on an older Troll), 27.5+ or maybe 26×4. Last year the spares situation in HP had improved hugely, but I’m still not sure about non-26″ anything over there, and courier delivery won’t work.

  • Tim Clarke

    Is that a Bob Ibex? Looks like lots of space to spare. Im curious about if it would fit 29+?

    Yes, 100mm QR fork.

  • Cass Gilbert

    I’ve since had a chat to a friend, who used ETs on his Troll for a tour across South America. He reckons they lasted 10,000km, over half of which was off pavement.

  • Cass Gilbert

    I think you’ll need an offset double to run any 27.5+ wheelset. Though you might be able to squeeze in a 2.8 with a standard mountain double… possibly…

  • Lewy

    Sounds like my type of tyre then. Thanks for the update.

  • Cass Gilbert

    Hi Stephen,
    I’m still a big fan of full fat for true exploratory backcountry bikepacking. In my mind full fat excels most where conditions are at their worst, so it kind of depends where you’re headed. Certainly, the freedom to roam is intoxicating! I’d still be tempted by full fat for true ‘expedition’ riding.
    From a personal perspective, Plus size suits my needs these days as much of my local riding includes arroyos, some trails, lots of forest roads, and a bit of pavement.
    From what I know, 26+ just fits the older Troll, if you run a 35mm rim and maybe a 2.8/3in tire. But it’s a big of a squeeze. Still, I’d definitely squeeze the biggest tires and widest rims I could if I had an older generation Troll. The days of touring on ‘skinny’ 2.1s and 25mm rims are over for me!
    For destinations like India, I’d probably just bring a spare 27.5+ tire and stash it in a hostel, for peace of mind more than anything. It’s rare you can’t repair a tire enough to limp on to a town where you can catch a bus back. So far, Ranger Toughs get a big thumbs up from me.

  • Stephen Poole

    Thanks Cass! My friend in Manali said the road from Darcha over the Shingo La into Padum should be complete this year and there’s a road down the Zanskar River from Leh to Padum being built too, apparently by a monk with a bulldozer. If the two roads aren’t finished they should be close, so I’ll ask again closer to departure. As there’s been a lot of snow this winter there may have been more erosionthan normal, and thus a fair bit of pushing or carrying. As well as Zanskar, I’m also hoping to get to the lakes in eastern Ladakh and a few corners of Himachal Pradesh, etc.

    Last year I did a short tour in HP, and even on the “national highway” up to Dharamsala 2.1″ tyres were pretty uncomfortable in places, so I’m intending to take something bigger. Due to a bit of serendipity I should end up with a fatbike frame next week, all being well, which can fit basically any size wheel up to 4″; I have a Rohloff.. I’m thinking 26″ Duallys ought to accommodate anything from 2.1″ or so (in an emergency) through 26+ to ~4″, so one solution would be to take two or three sets of tyres over there and stash them somewhere, say ETs(?) for better roads, and 26+ and/or 4″ for the uglier stuff. There’s a few months for testing here in Oz before I go, so I’ll just have to go on a few tours – there’s no alternative! :-)

  • Cass Gilbert

    My take? I think bringing several sets of tires will overcomplicate your life. Go for Plus or full fat and call it done! Also, I wouldn’t fit a 4in tire on a Dually; it’s too narrow a rim.

    Also, bear in mind that a 26+ wheelset will drop your BB height to a level that the frame might not be designed for. 27+ is likely a better fit/height.

    All this said, if it’s a fatbike with a wide Q factor, go with full fat tires and let it do what it does best! 65mm rims are likely the best option for versatility. They’ll take a 26in downhill tire if push comes to shove. Yes, 4in tires are slower on pavement. But they’ll still get you there (-:

  • Stephen Poole

    Thanks again Cass. The frame has a not-so-wide BB shell, so Q won’t be immense. The Duallys are on the way already, but there have been reports of successful ~4″ tyre use on them, i.e., on twentynineinches.com. Rim width might not be optimum for wide tyres but the BB height should be okay – I hate high BBs anyway. There’s some serious testing to do over the next few months. B+ is also possible if 26″ doesn’t gel 100%. ;-)

  • colavitos_ghost

    ECR might not be coming back, it seems. Not sure, though, as Surly can be a bit light-lipped when it comes to forthcoming changes in their line of bikes.

  • Smithhammer

    Bummer. Though it makes me all the more glad I bought one when I did. I haven’t ridden anything else that quite has the feel of the ECR…

    hey, thanks for the great review. which size is that ogre?chears from hamburg

  • Bob

    Does wheel removal/reinstallation in Surly’s Rohloff-compatible dropouts have drawbacks similar to those with the Pugsley dropouts, about which you’ve written elsewhere? I’m thinking of the need to loosen then reposition and tighten bolts holding the brake caliper. Thanks.

    hey Cass, great review, thanks. which size is that Ogre? Chears from Hamburg

  • Jutta Roggen

    Would you recommend the Troll or Ogre 27,5 for someone 5 feet, 4.5669 inches tall? I will use it for bikepacking, touring, light mountainbiking, commuting.. so a bit of do-it-all-bike. Other options are Genesis Longitude/Bombtrack Beyond Plus/.. but I keep coming back to Surly.

  • Cass Gilbert

    Sounds like you have it figured out! I’d still press for a one tire solution. The difference isn’t that great (IMO) unless you’re hitting pavement for thousands of kilometres…

  • Cass Gilbert

    Decimals and inches??! Yikes!

    You’ll have extra space between the tire and seatpack on a 26+ setup. But you’ll also have the choice of far more tires to choose from with a 27.5+ setup. Unless you’re heading on a RTW trip, I’d be tempted to stick to 27.5+.

  • Cass Gilbert

    It’s an XL, so the largest size for 2017. There’s a section in the copy where I talk a bit about sizing differences between the old XL and the new XL.

    You have mentioned that the basket is a wald 137, but what is the front rack? It looks a lot like surly’s 8 pack rack but you have the option to manipulate where the front stays are mounted. It also looks like the rack is mounted to the front “brake mount” below the crown. I like the appeal of this rack and I am waiting vehemently for this frame to become available for purchase. Thanks!

  • Jutta Roggen

    Thank you! sorry for the decimals, just copy pasted a conversion :)

  • Jutta Roggen

    When is it available?

  • Jutta Roggen

    ah found it: 30/4.

  • Raphael Bitsos

    thank you, yes i read that but i wasn’t sure which size you had

  • Cass Gilbert

    No, it’s fiddly. But not nearly as much as on the Pugs.

  • Cass Gilbert

    No worries! I was going to add that bear in mind a Troll with 26+ wheels will raise the BB, an Ogre with 27.5+ will lower it, respectively. It’s only really an issue on chunky singletrack.

  • Cass Gilbert

    It’s a Nitto M18, similar to a Rivendell Mark’s Rack. Much lighter and more minimal than the Surly 8-Pack. The Nitto is great for a small basket, the Surly is better for large ones.

    It’s mounted to the midblade eyelets or eyelets above the fork dropout, depending on how you configure it – rather than the brake mounts.
