Component / MTB Wheelset RS-M402-CB MTB Wheelset The RS-M402-CB represents the evolution of mountain bike wheel engineering — combining carbon precision with the proven strength of alloy rims. Designed for riders who demand responsiveness, control, and reduced weight, it is built to perform across the most demanding trails and terrains. Its carbon-reinforced hub trims rotational mass while improving torque response, and sealed bearings keep it rolling smoothly through harsh off-road conditions. Key Features ▪ Hybrid Carbon-Alloy Hub — aluminum body with carbon fiber reinforcement for enhanced stiffness and reduced rotational mass. ▪ Double-Wall Alloy Rims with reinforced rivets for impact resistance and long-term durability. ▪ Sealed RS Bearings (F2 / R4) for smooth, maintenance-free performance even in harsh off-road conditions. ▪ Boost & QR Compatibility — Boost (F15×110 / R12×148mm) and Quick Release (F100 / R135mm) for wide frame support. ▪ 8–13 Speed Freehub — slotted-drum tower ready for modern Shimano/SRAM-type drivetrains. ▪ Lightweight 1.97kg (pair, 29") with 25mm internal width for responsive trail performance and optimal tire support.
