This is the Shimano WH-RS81 C24 Clincher Wheel Set. The rims on the WH-RS81-C24-CL wheels feature a proprietary, in-house construction where carbon is laminated to a thin aluminum rim. Giving you the best of both worlds. The carbon portion is light and stiff does an excellent job of dampening the ride while enhancing the strength of rim at the same time. The alloy braking surface is far superior to carbon and is incredibly durable reducing the risk of carbon wheel failure from overheating.
The WH-RS81-C24-CL is 11-speed compatible and comes with a 1.85mm spacer so it will work with 10, 9, 8-speed and SRAM too. The hubs are based on Dura-Ace design featuring angular contact bearing and labyrinth seals. The flanges are super wide increasing the distance of the spokes between the flange creating a wider footprint for a far stronger and more stable wheel. The front wheel is 16-hole with a radial lace, while the rear is 20-hole with a 2X lacing pattern.
Many factory wheels have a stiff ride quality because they use fewer spokes at a higher tension. Shimano builds the RS81-C24 to ride like a bomb-proof hand-built wheel that handles the rough stuff with no problems and still remains stiff and compliant in your sprints and high speed corners. You also get a particular amount of built in durability with the hubs, because of the design - they will last many seasons with no required maintenance. Over the past few years this carbon-hybrid rim design has proven to be an ideal blending of both materials strong suits, while not inheriting any of their weaknesses. Includes skewers, rim tape, and spoke wrenches.
