After being smitten by the 29+ platform while riding across Africa, I thought I’d make the Surly Krampus my go-to trail bike and bikepacking rig. I’ve said it all before here and here, so I’ll just get straight to the photos and build details:

The Krampus kitted out for a Pisgah trip with a Revelate Harness, a DIY Framebag, and a Revelate Viscacha Seat Bag.

    Nice review Logan.

    Still very much got my heart set on building a Krampus up once I return from South America.

    Thanks for the tantalising photos!

  • Thanks Mike! Seems like a fatbike is great for your travels down there…

  • Kyle

    Planning a weeklong fat/rafting trip here in the east and a friend of mine is curious if a Krampus would be capable of long days of beach riding? I’m assuming it would be fine if sand conditions stayed relatively hard packed but our conditions are likely to change constantly. Thanks and I’m really digging the content on your site. Keeps the stoke meter pegged for sure.

  • Thanks Kyle! Yeah, deep sand might be tough on 3″ Knards. I rode them on a chunk of the Sahara as well as other fairly sandy places and once you hit the deep stuff they don’t quite float as well as true fat tires. I found myself squirreling out a few times. Doable, but not ideal. Air pressure makes a big difference as well. Where’s the route you guys are planning?

  • Kyle

    Do you have an email I could chat with you on? Trying to keep this trip low key.

  • Sure pedalingnowhere at gmail …

    Have you tried the ECR fork on the Krampus by chance? Looking at the specs, the offset is the same but the ECR is about .5inch shorter. Just wondering if you tried it. I love both bikes and torn which way to go, but being singletrack minded, I like the Krampus, but I want the options of the ECR for mounts. I’ve read about installing rivnuts, and hose clamps, etc. I rode a Large Krampus OPS and a Large ECR yesterday, and was surprised by the small but nimble feel, the Krampus had. I suppose I could buy the ECR fork and try it, simply for the Anything cage ability, then rivnut the downtube of the frame if I truly felt the need. Dammit Surly!

  • Not to worry Mike! Check out the Krampus vs ECR at the link above. In the comments you’ll see some discussion anout a Krampus fork sold by surly with the triple cage mounts.

    Logan, any thoughts on putting the Jones H-Bar on the Krampus? I’m wondering wha the advantages would be? Looking at doing the CT in August… Will

  • The loop bar is just a personal preference. I know a lot of people who love them. Personally, I haven’t gotten in to the big sway angles…

    Howdy, I’m 18 and building my own Krampus 2017 bikepacking rig. I’ve had a tough time finding a crankset for it. I know the surly OD would work well but knew I didn’t want the 39/26t rings. I noticed you swapped them for 36/22t rings. Is there a way I can purchase this set up without having to buy it stock and replace the rings? I hate waisting money on those unwanted rings. Also, can I get the replacement rings in Black from surly instead of bare? This would help me out a lot, thanks.

  • Yeah, you can order it from any QBP dealer with the 36/22 combo. the outer ring (36) is black and the 22 is stainless steel (which is why it’s raw… bit it will last forever). Or, here it is at Treefort:

  • Whoops, maybe not. Sorry about that. That was the 100mm crank.

  • If you get the 39/26 and a 11-42t cassette (like the SUNRACE CXMS3) you should be alright when it comes to gearing though. I ran a 1×11 on a 29+ in Kyrgyzstan (lots of climbing) with a 26t chainring up front and 11-42 in the back… plenty of climbing gear.
