Details

With the Thunderbolt Carbon 70, Rocky Mountain reveals 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. Fox keeps your tires gripping the course with a DPS EVOL shock and 34 Performance Elite fork, lightweight hardware that can damp with the heavyweights.

Speed becomes a natural extension of your body as you crank up the SRAM GX Eagle 12-speed drivetrain, with a broad gear range that offers impressive climbing prowess and a fast top-end with minimal componentry. Maxxis DHR II tires keep you glued to the trail with race-winning traction and are wrapped around Race Face ARC rims for the winning advantage in lightweight strength. Your white-knuckle descents are no sweat for Shimano XT brakes, giving you peace of mind that braking is under control so you can focus on carrying speed all the way to the finish line. The Fox Transfer dropper post gives you an edge on both ascents and descents, ensuring your body is always in the right position for the job.

The RIDE-9 adjustment system allows riders to quickly fine-tune their geometry and suspension with a pair of Allen keys. Nine configurations are possible thanks to two interlocking chips. Position 1 geometry configuration shown below.
