Overview
Rear Wheel Reynolds A309 XC PRO 29" 148x12 6-Bolt XD / Micro Spline
Reynolds A309 XC PRO is a high-performance 29-inch mountain bike rear wheel engineered for the demands of modern cross-country riding. Combining excellent stiffness, rapid power transfer and long-lasting durability, it delivers precise handling and efficient pedalling on technical trails, fast climbs and demanding XC courses.
The rim is constructed from high-strength 6069 aluminium alloy, featuring a welded joint and a sandblasted matte black finish. Its 30 mm internal width provides optimal support for modern wider XC tyres, improving traction, tyre stability and overall riding control. Reinforced rim sidewalls help resist impact damage, including dents and pinch flats, when riding over rough terrain.
The Tubeless Ready rim profile allows the use of tubeless tyre systems, supporting easy inflation and secure tyre retention even at lower pressures. The wheel is built with Wheelsmith DB14 double-butted Straight Pull spokes and lightweight aluminium nipples, providing an excellent balance of strength, low weight and precise wheel stiffness.
At the centre of the wheel is a fully CNC-machined Ringlé SBX rear hub, featuring an exceptionally fast 4° engagement angle. This ensures almost immediate power transfer when pedalling resumes, making it especially advantageous during technical climbs, rapid accelerations and challenging trail sections.
The rear wheel comes complete with two interchangeable freehub bodies – SRAM XD and Shimano Micro Spline. Both are included in the package, allowing the wheel to be used with SRAM XD and Shimano Micro Spline cassette systems without purchasing an additional freehub body. Simply select the appropriate freehub body for your drivetrain configuration.
Designed for 148x12 mm Boost thru-axle rear spacing, the Reynolds A309 XC PRO features a 6-bolt disc brake mounting interface. Its 28-spoke construction and approximately 947-gram weight make it a durable and performance-oriented choice for demanding cross-country mountain bikers.
