Product Information

Charlie says... these are excellent bikes, and what i choose to ride. Big wheels keep on rolling. And just like in surfing or skateboarding, if youare going fast, everything is easy, and its all more fun.

Weird pricing on Large and XL... yes, some of these bikes have been on expensive journeys to get here. We believe these are the only XLs and Large's  left in the UK and Europe. And we only have one of each.


There is no need to for us to immerse you once again in the bath that is the Krampus, or 29+ for that matter. Go here if you really need the meat and potatoes of what this bike is all about. There's plenty of info there to get you up to speed. But you probably know that already, don't you?

The "Ops" in Ops here at Surly is short for "Optional" and to us that means that this build doesn't just have some fancy new trim package, but is spec'd and in this case designed a bit differently to offer the user "optional" utility. Other utility. The Krampus Ops comes with a Surly OD crank, giving you far more possibilities for drivetrain (you can convert it to an off-set double by adding one of our chainrings and then using a direct mount standard front derailleur and an adapter to give you optimal tire clearance). So a few more options there.

The Krampus Ops also features our Modular Dropout System (MDS), allowing you to change up your drivetrain according to needs. Frames ship with MDS dropouts in 10mm track end singlespeed, standard vertical with derailleur hanger and a 142 x 12mm thru-axle versions. So, you may do what you will. Again, with all these options how will you ever get out of your house? You'll manage.

Krampus hub spacing is standard 100mm front and 135mm rear. It's got clearance for disc rotors up to 185mm and is designed to run a high direct mount standard front derailleur. For best chain/tire clearance, we recommend either a Surly O.D. 2x crank (which comes on the complete)(oh the options) or a 1x system. Other brands 2x cranks will work but may cause some chain-on-tire rub in the easiest gear combo.

Enough options for you? Probably not, but we're not machines. Now go get on and get off.

Duncan - Reading
Love this bike! I was looking for something different...and I've found it. This gets used for commuting, bridleways and single track riding...and gets used most days of the week. Possibly the most comfortable bike I've ridden. Excellent grip on the trails. With more weight and the bigger tires it did take a few rides to get used to it and focusing on maintaining momentum is rewarding. Good solid components and the bike feels like it will last a long time. Great service from Charlie, received the bike a couple of days after I ordered it and my email queries were responded to promptly.

Damn you Jack, this has taken over my life! Long overdue a review... Big wheels, big tyres, big momentum. And then some... Charlie, sell more!! Everyone must have one!!!! A bike that can finally conquer my local limited trails that have been destroyed by excessive use, horses and heavy rain. I thought only a fatbike would cope with the local bad bits but, no, this has achieved and gives yet more flexibility for other stuff over a full fat! It's a dream downhill (fast), a dream uphill (in the right gear) and pretty damn acceptable on Tarmac even with a bit of squish in the tyres (it's just so cool I'm not even fussed about speed)! I'm a heavy chap and the stock wheels are taking it (I usually build my own 36 spoke, top quality hubs, bolt thru on all mountain rims) The chief troublemaker from surly told me that this bike will happily take 400 pounds of fully loaded abuse so if you want a strongun... Buy it! Also, heavily loaded, there's no wobble! I have commuted, off roaded, shopped on it, ridden to the pub (obviously.... Has to be shown off) and am sorting it eventually with Rohloff rear and Schmidt Dynamo front for a trip planned next year to South America (my half Colombian mate is gonna Sancho Panza alongside on the family donkey Shakira as I explore that part on my planned travels) I'm dead chuffed and this sits proudly next to my Specialized Stumpjumper FSR Expert Carbon as it rests in its bedroom in the garage. Little to go wrong and it's actually refreshing in its simplicity riding such a well designed and bomb proof rigid! I do look forward to a decent sus fork for interchangeable hi jinks tho! My only quibble is the Avid BB7's as I've always had top of the range hydro's. As a heavy rider on a fully loaded steed tanking downhill I feel it's prudent to put on some decent modulating, fin cooling hydro's but I will keep the BB7's for off grid expeditions where, in a worst case scenario, they are easily repairable or for the cable to be removed and used to suture a flesh wound in a Johnny Rambo stylee! Check out the below link if you need convincing! I found it damn inspirational and informative. Proof that this bike is the best for everything (an expedition trail test in, none other than, South America)...
