Interested in mixing up rides on tarmac and singletrack? Putting in long days off-road? Some fire road bike-camping? A ride across the continent? All-City says no problem to all of the above with its new Gorilla Monsoon…

Posted by Logan Watts

Steel dirt drop bikes are always nice to look at and fairly versatile, but when paired with big tires they become an extraordinary thing of beauty. Lately, more and more companies are taking this to heart in effort to create a perfect do-it-all bike. With its latest creation, All-City grabbed this motif and ran. Featuring a 73mm bottom bracket shell and 27.5″ x 2.4″ WTB Riddler tires on a classically designed steel frame, the new All-City Gorilla Monsoon looks to be a stylish bike that can tackle pretty much anything.

All-City Gorilla Monsoon, 27.5 monster cross bike

  • Highlights
  • Frame/fork: “612 Select” Steel
  • Angles (58cm): 71.5° Headtube, 72.5° Seattube
  • Stack/Reach: 621mm/389mm
  • BB Drop/Chainstay: 71.5mm/430mm
  • Bottom Bracket: 73mm English
  • Hub specs: 12x142mm / 100x15mm Thru-axle
  • Seatpost: 30.9mm
  • Max tire size: 27.5 x 2.4″
  • Price: $1999 (complete), $850 (frame)

The Gorilla Monsoon frame is built from All-City’s ‘612 Select’ tubing. Like other All-City bikes, the Minneapolis-based company kept to the ‘handbuilt’ aesthetic with a lovely bi-plane crown steel fork and details such as reinforced bottle bosses. The biggest surprise on the Gorilla Monsoon is the 73mm bottom bracket shell which provides the extra tire clearance and allows MTB cranks. The frame also features front and rear thru-axles, front and rear rack and fender mounts, compatibility with Surly-8 and 24-Pack racks, stealth dropper post routing, 27.5 x 2.4” tire clearance (650b x 48 with fenders), signature All-City dropouts, E.D. coating for rust prevention, and three water bottle mounts. In addition there are three cable mounts on the downtube, giving you the option of adding a front derailleur or a dropper post. For reference, here’s the max ring sizes for each setup: 1X = 38T, 2X = 28/42, 3X = 26/36/48.

The Gorilla Monsoon was also built to handle a variety of other tire sizes, such as 650b x 47mm tires. According to All-City, this results in a slightly lower BB which gives the bike “excellent manners when riding with a load”… a setup they fully endorse. If you want to run 700c wheels and tires, the frame maxes out at 42mm which will raise your BB by 8mm. 700c x 38 keeps the BB about the same.

    What a pretty bike. Like the wheel/tire set. I think they missed the mark on the lack of bolt-ons on the fork. And with those 650bs there is plenty of room on the underside of the downtube but only two bolt-ons

  • Yeah, I’m always bummed to see companies fail to capitalize on fork blades. IMO, it’s the perfect place for water bottles…

  • Looks like the steel drop-bar gravel super fun times bike I’ve been waiting for…

  • T.R. Beck

    Too bad about the lack of singlespeed compatibility. Could have been the one.

  • Coen van den Berg

    Looks Nice! @logan, speaking of do it all bikes, will you be posting a review of the Kona Sutra LTD 2018?

  • Yes! Unfortunately I got waylayed a bit due to an injury. But, I got some help and the review should be coming soon enough. I will say that it’s a great bike and one that I’ve thought of purchasing…

  • multisportscott

    So this is an All-City version of the Surly Midnight Special?
    It uses a MTB width BB to make room for the wide tyres? By using a straight steerer tube I think it limits what modern carbon forks you could upgrade to.

  • Greg Johnson

    Dang it! Still a sweet looking bike and moderate price. Just not quite there for bikepacking.😕

  • Greg Johnson

    Good call

  • cwcwcwcwcw

    super easy for local frame builder to add screwholes to forks. Or if they are far away, just send them the forks.

  • I’m-buying-one

    Nope. The Midnight Special is a mid-trail bike. Expect it to handle like a classic road bike on the road. Unfortunately also expect it to be sketchy on a technical descent.

    The Gorilla Monsoon is a higher trail bike, up in touring/gravelbike territory. Expect it to be less lively on pavement than the Midnight Special and much better handling offroad.

    I’m super into this bike, but it’s a pretty big bummer that they’re already all sold out/reserved. Maybe some folks will luck out and be near a shop that ordered some for stock, but looks like everyone else will have to wait until August or so.

    I think All-City is doing some really cool stuff lately (this, Electric Queen, Cosmic Stallion) but I don’t understand why they do such limited runs. The Electric Queen is also completely sold out.

  • Michael McDonald

    last I checked there were plenty left, may wanna double check!

  • Michael McDonald

    Not really that similar at all to a Midnight Special, it’s a CX geometry with 27.5 x 2.4 inch tires on it. The midnight special is a road bike with 650b x 47. Quite different.

  • joshhh

    believe me, I’ve been double checking, and also emailed our sales rep just to make sure :)

    definitely zero Gorilla Monsoon complete bikes or framesets available from the distributor (QBP) right now, and that’s been the case since a few days after they were announced, 2 or so weeks ago . The framesets went quicker than the completes. The only Electric Queens remaining are 2 XL completes (if any tall folks see this and want one, call your LBS soon!)

  • Chucky Beans

    Does anyone know how much this bike weighs?
    Looks like a very cool bike.

  • Chucky Beans

    found out: 28 pounds complete in 55 cm. ooph.

  • Pancho

    Greg, just curious on what you mean its not quite there for bikepacking? I’m in the market for a good all rounder and was thinking of this or a Crust Evasion…. What about the Gorilla Monsoon isn’t good for bikepacking?

  • I think it makes a fantastic bikepacking bike – also interested to see why Greg thinks it isn’t!

  • Greg Johnson

    It’s the lack of bosses on the fork. This is great storage space for going off pavement. A number of different cages and bags for this option. I suppose you can swap out forks but that would ruin that sweet paint job.

  • Nate Smith III

    All City is a pretty small brand so order quantities tend to be lower especially on new models until they are proven out. My guidance would be to let your local All City dealer know you are interested so they can try to get one when they drop into open stock. As an FYI, if you are an XL, there are a couple that are dropping into inventory early tomorrow. If tall and interested, call your dealer and put your hat in the the ring.

  • joshhh

    I manage a shop that sells All-City, so I am quite familiar.

    On top of wanting one myself, part of my frustration is having to explain to customers that a bike which came out less than a week ago (at the time) is already sold out for at least a couple months. Some people are fine with that and wait, some are put off by it.

    That said, All-City is definitely one of my favorite brands (including ones we don’t sell), I just wish the spotty stock wasn’t such a frequent problem. I’m still planning to get one of these once they’re available as a frameset again.

  • Nate Smith III

    Trust me, it’s frustrating for all of us in the supply chain. It’s always tough to gauge interest and we’d rather err on the side of caution than to have shops blow out product at season’s end at below market value.

  • Harry Meyer

    Universal Cycles in Portland should have them in stock this week

  • Andrew

    White Industries Eno hub should fix that issue

  • Andrew

    oops forgot it was thru-axle, too bad. I can’t think of an eccentric bb that would work either.
