Shimano Dura Ace WH-R9370-D Tubeless Disc Carbon Rear Wheel

Shimano DURA-ACE WH-R9370-DISC-TL-R Carbon Rear Disc Wheel – Maximum Aerodynamic Performance

Shimano DURA-ACE WH-R9370-DISC-TL-R – a full carbon rear disc wheel designed for time trials and triathlon racing. It helps riders maintain a high pace more efficiently and conserve energy throughout long, high-speed sections. Paired with the C99 front wheel, it creates an aerodynamic wheel combination developed for top-level time trial and triathlon competition.

Key Features:

• Full disc construction: reduces aerodynamic drag and helps maintain high speeds for longer.
• Weight: 987 g.
• Advanced aerodynamic profile: developed using more than 30 billion computer simulations.
• 23 mm internal rim width: optimised for 28–30C tyres.
• Lower rolling resistance: the rim width helps maintain an optimal tyre profile and lateral stiffness.
• Hooked tubeless rim: 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 hub: provides high drivetrain stiffness and efficiently transfers the rider’s power.
• Pairs with the C99 front wheel: designed to create a highly aerodynamic racing setup.
• Intended use: time trials, triathlon and long courses where aerodynamics and maintaining a consistent speed are the main priorities.
