Don't waste another watt. The WH-R9370-C36-TL is SHIMANO's newest RACE wheelset for highly dynamic situations encountered primarily on climbs. Playful by design, leveraging the inherent properties of carbon spokes, a dedicated front/rear layout (18 front / 21 rear spokes) combined with a purpose-designed hub achieves overall system weight reduction while ensuring the stiffness required for responsive power transfer. An optimized rim layup reduces overall system weight to 1,172 g (178 g lighter than the previous WH-R9270-C36 model). Despite its low 36 mm profile, the rim shape enhances aerodynamic performance, delivering sustained speed and snappy acceleration through gradient changes and pace increases.

Features
Rim depth: 36 mm (Front & Rear)
Designed with 28-30C tires in mind: 23 mm internal rim width lowers rolling resistance and preserves tire stiffness
Aerodynamically optimized rim: Despite its low 36 mm height, 2 million shape simulations delivered a 7% aero improvement compared to the previous model
Carbon spokes: Carbon spoke design optimized for aerodynamic efficiency, stiffness balance in race environments
Spoke pattern — Front 18 / Rear 21: A dedicated layout that pursues low weight while providing the stiffness needed for responsive acceleration
Hooked tubeless rim: Supports a broad range of tire compatibility
Cup & Cone bearings: Excellent serviceability and precise adjustment deliver both speed and durability
Rear wheel — DIRECT ENGAGEMENT: Superior drive stiffness for maximum power transfer
