The bike that started it all — the plus-size movement that is. The Krampus Front Sus takes it a step further with the addition of front suspension and a dropper post, providing more traction, more control, more fun. And as you'd expect, the frame features Surly’s Gnot-Boost rear hub spacing of 145mm; compatible with Boost 148 x 12mm thru-axle, 142 x 12mm thru-axle and 135mm quick-release hubs. Rolling on 29” x 2.6” tires, this bike can get you over just about anything you point it at.


  • 100% Surly Chromoly steel frame; double-butted main triangle and 44mm headtube
  • RockShox 35 Gold RL A2, 120mm travel Suspension Fork
  • Surly custom trumpet frame tubes for greater stiffness and durability
  • Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru-axle, as well as 135mm with 10/12 washer
  • Internal dropper seatpost routing

  • Clearance for 29 x 3" tires

I thought everything was great. The bike arrived quickly, nashbar stocked exactly the type of bike I was looking for, and it was a decent price. I am a bit miffed as to why I didn’t get a t shirt though. Oh well. The bike’s enough entertainment to keep my mind off of the heartache.
