Shimano XTR M9220 Disc Brake Pair Upgrade Kit (4-Piston) 2026

SHIMANO XTR M9220 - Hydraulic Braking Kit (Upgrade Kit) - the ultimate braking power for Enduro, technical Trail, and E-MTB: Control, Heat Management, and Reliability.

This Shimano XTR M9220 brake kit is the high-performance choice for Enduro, aggressive Trail, and Electric Mountain Bike (E-MTB) riders. Designed for those who tackle long, steep descents with high inertia, this Upgrade Kit delivers massive stopping power without compromising on precision. The 4-piston calipers combined with ergonomic levers ensure a consistent brake feel and superior heat dissipation, even under extreme conditions or on heavier bikes. Whether you're racing against the clock or exploring technical mountain terrain, the M9220 provides the confidence of a perfectly modulated and ultra-powerful braking system. The J-Kit technology integration simplifies the assembly process, making it ideal for frames with internal cable routing.
