All Box One forks are engineered and crafted using our Oversized Technology. These forks are the single most important component in the quest for bike control. We’ve moved carbon from areas of low stress to areas that handle high load. Those muscular shoulders aren’t just for looks as they are integral to achieving superior steering stiffness. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: This particular model fork is tailored for larger-sized racers and therefore includes a lightweight 1-1/8 inch 7000 series aluminum steerer tube and 10mm cold-forged dropouts.

Once again, SRAM pushes the envelope with their Powerdome X XG-1090 10-Speed Cassette. Light, stiff, quick, and quiet thanks to the ultra-strong, hollow, one-piece design and StealthRing elastomers, this cassette is worthy of even the nicest road machines. SRAM has added elastomer rings between every cog to provide a 'bed' where the plates of the chain interface with the cog. These elastomer StealthRings make for whisper-quiet operation. It's light, too, with the small 11T cog separate, and the remaining 9 cogs milled from a solid block of tool-grade steel pressed onto a single aluminium cog (the largest one). And, to REDuce even more weight, excess material in the space between each cog is milled away.

The SRAM Rival 22 Mechanical Shifters are modeled after the phenomenal RED shifters. SRAM not only trickled down 11-speed compatibility, but ErgoFit elements such as a slightly longer brake lever to enhance control, independent reach adjustment for brake and shift levers, and a smaller diameter hood with a taller top shape to increase rider control and improve finger wrap. Because you're able to shift from the hoods, drops, and even when sprinting, the Rival levers offer a competitive advantage that can't be touched. The single-lever-shifting design allows for faster, smoother shifts while being completely independent of the brake levers, eliminating the possibility of engaging the brakes when you shift. Plus, the forged aluminum brake lever and shift paddle offer a beautiful balance of low weight and impressive durability.
