Surly Krampus Front Suspension
Details
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.
