The Surly Krampus was the start of the 29+ bikes! The Ops comes in flat black and is made with 4130 CroMoly steel main triangle, TIG-welded, custom butted with a sweet CS yoke. The fork is also made with 4130 CroMoly and is 100–120mm suspension corrected. The fork is a straight 1-1/8˝ steerer tube with 203mm disc brake clearance.

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. 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 while complete bikes ship with the 10mm vertical chip. 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 MDS rear chips allow you to choose either 135mm or 142 x 12mm thru-axle hubs. 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.
