This bike is what happens when you go into the Internet and find the most expensive, capable, dirt clod-crushing, rock-spitting machine in the MTB phylogenetic tree. The Spark Limited is built like a smart weapon that never explodes. It is all carbon, except for the seat, which is Kevlar, the rear shock, which is precision-cut by a Swiss machinist and only 240 grams anyway, and some of the highly customizable gear and chain parts. The bottom line: this bike is light, only 20.26 lbs, as shown. And it’s strong like a missile, a smart missile that destroys mountains but never blows up. Your skull on the other hand…  this bike will give you confidence, but it won’t protect your head.
