Overview
About this bike
Fast as lightning! The Thunderbolt is our vision of a perfect XC-trail bike. With the Thunderbolt we’ve designed an all-new carbon frame that pushes the rear travel to 130mm, increases stiffness, lowers the rate curve slightly, and gives the frame a host of next-generation features—but keeps its playful geometry and wide range of RIDE-9 adjustments. The Thunderbolt is at home on technical climbs, powering through rough stuff, and popping off every trail feature you lay eyes on.
