Shimano Dura Ace WH-R9370-C36 Tubeless Disc Carbon Front Wheel

Shimano DURA-ACE WH-R9370-C36-TL Wheelset – Lightweight Speed for Climbing

Shimano DURA-ACE WH-R9370-C36-TL – a lightweight carbon road bike wheelset designed for mountainous courses and frequent changes of pace. Its responsive performance helps riders use their power efficiently when climbing, attacking or accelerating as the gradient changes, while the balanced construction maintains the precision and stability required for racing.

Key Features:

• 36 mm-deep rims: a lightweight and versatile design developed for mountainous terrain.
• Wheelset weight: 1,172 g – the front wheel weighs 523 g and the rear wheel 649 g.
• 178 g lighter wheelset: compared with the previous WH-R9270-C36 model.
• Improved aerodynamics: two million shape simulations resulted in a 7% improvement in aerodynamic efficiency.
• Carbon spokes: optimised for low weight, aerodynamics and the stiffness required for racing.
• Dedicated spoke layout: 18 spokes are used at the front and 21 at the rear to balance low weight with efficient power transfer.
• 23 mm internal rim width: optimised for 28–30C tyres.
• Lower rolling resistance: the rim width helps maintain a stable tyre profile and lateral stiffness.
• Hooked tubeless rims: suitable for tubeless tyres and compatible with a wide selection of road bike tyres.
• Cup & Cone bearings: a precisely adjustable and easy-to-maintain system ensures smooth, long-lasting performance.
• Direct Engagement rear hub: provides high drivetrain stiffness and rapidly transfers the rider’s power to the rear wheel.
• Intended use: mountainous road races, fast climbs and dynamic courses with frequent changes of pace.
