Rear Wheel Shimano Ultegra WH-R8170-C50-TL-R 11/12-Speed 12x142 mm

Shimano Ultegra WH-R8170-C50-TL-R is a high-performance carbon rear wheel combining excellent aerodynamics, low weight and outstanding rigidity. Part of the Shimano Ultegra R8100 series, the C50 with its 50 mm deep rim profile is designed for performance road cycling, delivering an ideal balance of speed, efficient power transfer and riding comfort. It is an excellent choice for racing, intensive training and long-distance road rides.

The full carbon rim shares its aerodynamic profile with Shimano Dura-Ace R9200 series wheels. Its 50 mm depth helps reduce aerodynamic drag at higher speeds while maintaining predictable handling in different riding conditions. Low rotational inertia and a rigid construction provide responsive acceleration and efficient power transfer on flat roads, climbs and descents.

With a 21 mm internal width and 28 mm external width, the rim is optimised for modern, wider road tyres. The Tubeless Ready construction supports both tubeless and conventional clincher tyres with inner tubes. The wider rim profile provides improved tyre support, helping achieve an excellent balance of rolling efficiency, grip and riding comfort. Recommended tyre sizes range from 25-622 to 32-622.

The rear wheel features 24 stainless steel spokes with Shimano's OPTBAL spoke arrangement, designed to optimise spoke tension balance and improve wheel rigidity under drivetrain loads. This contributes to efficient power transmission and a stable, responsive riding feel, even during powerful acceleration.

The lightweight aluminium rear hub features a Shimano HYPERGLIDE HG freehub body compatible with Shimano 11- and 12-speed road cassettes. Labyrinth and contact seals help protect the hub bearings from dirt and moisture. The CENTER LOCK disc rotor interface provides compatibility with suitable disc brake systems, while the 12x142 mm E-THRU axle standard ensures secure attachment to the bicycle frame.

Weighing approximately 872 grams, the Shimano Ultegra C50 rear wheel is an excellent upgrade for riders looking to improve their road bike's aerodynamic efficiency, acceleration and power transfer without unnecessary weight.
