Shimano’s latest Dura-Ace WH-R9370 wheel series marks a significant evolution in high-performance cycling technology. This new lineup introduces carbon spokes, wider rims, reduced weights, and a specialized time trial configuration featuring a 99mm front wheel paired with a rear disc.<\/p>\n
Comprehensive Wheel Range<\/strong><\/p>\n The WH-R9370 series encompasses the following models:<\/p>\n These wheels have been developed in collaboration with professional cyclists, including teams like Alpecin-Premier Tech and Fenix-Premier Tech, as well as athletes such as Kat Matthews and Mathieu van der Poel. The lineup is fully tubeless-compatible, aligning with modern tire standards.<\/p>\n Weight Reduction and Carbon Spokes<\/strong><\/p>\n A standout feature of the WH-R9370 series is the incorporation of carbon spokes, contributing to notable weight savings compared to the previous Dura-Ace R9270 wheels:<\/p>\n This reduction is achieved through the use of carbon spokes in two profiles: Aero (4.0 x 1.1mm) for the C36, C50, and C60 models, and Super Aero (5.2 x 0.8mm) for the C99 front wheel. The C99 front wheel features 16 Super Aero spokes, enhancing its aerodynamic performance.<\/p>\n Rim Design and Tire Compatibility<\/strong><\/p>\n The rims have been designed to accommodate modern tire sizes, with internal widths of 23mm, suitable for 28-30c tires. Shimano’s testing at 48 km\/h with 30c tires demonstrated up to 2.7 watts less drag compared to the previous generation. The C50 and C60 models also feature front- and rear-specific external widths, with the C60 measuring 31.5mm wide at the front and 32.3mm at the rear.<\/p>\n Hub System and Sealing<\/strong><\/p>\n Maintaining Shimano’s preference for cup-and-cone hubs, the new system includes replaceable bearing cups, improved waterproof sealing, and reduced friction. Shimano claims that this revised setup exhibits 30% lower rotational torque compared to typical cartridge bearings in their own testing.<\/p>\n Pricing and Availability<\/strong><\/p>\n The pricing for the WH-R9370 wheelsets is as follows:<\/p>\n Shimano has announced that these wheels will be available starting September 2026.<\/p>\n The introduction of the WH-R9370 series signifies Shimano’s commitment to advancing cycling technology, offering riders a range of high-performance wheels tailored to various disciplines and preferences.<\/p>\n\n
