Rocky Mountain Thunderbolt Carbon 90 BC Edition

With the Thunderbolt Carbon 90 BC edition, Rocky Mountain reveals an all-new carbon frame and long-stroke shock that push the rear travel to 140mm, 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 BC excels as a trail bike and on today’s increasingly rowdy XC courses. Fox keeps your tires gripping the course with a DPS EVOL Performance Elite shock and 36 Performance Elite fork, both ready to take on terrain that would far exceed the capabilities of most XC bikes.

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 Minions deliver unheard-of traction that lets you carve your most aggressive lines, and they’re wrapped around Race Face ARC rims for the winning advantage in lightweight strength. Your white-knuckle descents are no sweat for Shimano XT brakes with Ice Tech rotors, 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 Race Face Turbine dropper post gives you an edge on both ascents and descents, ensuring your body is always in the right position for the job.
