With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Surly Krampus Ops 29+ Mountain Bike Black Information

Brand : Surly - Bikes/Frames

Code : 5SUKR1K

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.

Note: Krampus Ops Bikes come fitted with standard vertical dropouts ONLY

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.
