Scalpel-Si Carbon 4

BUILT FOR XXC

The ultimate race bike for the rough and tumble realities of modern XC. It’s the lightest, stiffest XC dually on the planet, with radical new XC geometry to own the climbs, rule the descents and decimate the competition.

TO SUM IT UP 

The lightest, stiffest, best climbing, descending, all-around fastest XC race bike ever made. The new XC gnarly. The new Scalpel-Si is gnarlier.
