Shimano WH9000 C24 Wheelset

Description

Shimano’s lightest Dura-Ace wheel has been completely redesigned, boasting a brand new hub and improved rim. Best of all they’re now compatible with Shimano’s 11-speed system.

The C24 wheels use a carbon/aluminum hybrid rim where the carbon is actually structural rather than a fairing as used by some wheel manufacturers. The standard aluminum braking surface leads into a half millimeter thick alloy rim, which is then reinforced with a carbon fiber layer on the exterior. Like carbon cranks that use an alloy skeleton, this hybrid leads to a light yet incredibly stiff wheel.

The 9000 rim has also been updated with a wider profile, resulting in an improved tire contact patch and more aerodynamic performance. The low profile 24mm depth means they spin up fast, won’t slow you down on the climbs or handle poorly in cross winds.

Another place where this new wheel stands out is the 9000 Dura-Ace hub. Top quality angular contact ball bearings roll as smooth as ever, and they’ve been made even easier to adjust thanks to the tool-free “digital click” system, so you can put the cone wrenches back in the tool box. Over-sized A7075 Alloy axles are incredibly rigid yet lightweight, and a wider rear flange spacing furthers stiffness even more. The addition of a full Titanium 11-speed compatible freehub body shaves a few more grams while offering great wear resistance.

The WH-9000-C24-CL features stainless double butted and bladed spokes. 16 spokes laced radially front with 20 spokes laced 2 cross in the rear. Off-set rear rim decreases “dish” for higher non-drive side spoke tension and increased durability. Black Rim/Spokes with alloy spoke nipples.

The Dura Ace WH-9000 C24 CL Wheelset is compatible with traditional inner tube-type clincher tires. Dura-Ace quick release skewers are included. For use with Shimano/SRAM 8/9/10/11-speed cassettes. Claimed weight: 1356 grams per wheelset.
