Shimano’s WH-RX830 wheelset is the perfect compliment to Shimano’s R785 road hydraulic disc brakes With 10 and 11-speed compatibility, a wide 17C tubeless, carbon laminate rim, and Centerlock rotor mounting the WH-RX830 is optimized for miles and miles of reliable, lightweight performance Shimano is here with a road disc wheel that is competitively priced and offers excellent features for the enthusiast. It is disc only so there is no braking surface in the outer carbon fiber laminate shell. But there still exists an aluminum skeleton for strength and solid tubeless compatibility It is 11-speed compatible but it will still work 10 speed clusters. The internal rim width is wide at 17c, allowing the tire to sit better for more volume and cornering traction. And finally, the rim is a little deeper and the wheel is very stiff, following the Acceleration Concept technology of Shimano which maximizes stiffness while minimizing weight And finally, high quality ball bearings and races, are used on these wheels for the best durability while still providing drag-free performance. Sealed bearing and expensive ceramic types are interesting for design and axle compatibility is concerned. But for drag-free and wobble-free performance for years to come, the Shimano cup and cone bearing system fits the bill Features: Acceleration concept, 17C, carbon laminated tubeless rim Ultegra level 10 and 11-speed compatible freehub 135mm OLD 140mm Centerlock rotor compatible High quality sealing Cup & Cone bearing system Quick release onlyA 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products) Buy Shimano Wheels from Chain Reaction Cycles, the World’s Largest Online Bike Store.
