Surly Krampus Ops 29+ Frameset 2015

There is no need to for us to immerse you once again in the bath that is the Krampus, or 29+ for that matter.

The Krampus Ops 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.
