WHEELS: Shimano Dura-Ace Wheels 7800

The NEW WH-7800 wheel set is the first to earn the DURA-ACE pedigree and adds yet another performance advantage to the overall superiority of the new system. With a focus on speed, the rim profile of 24mm yields a substantial reduction in weight while maintaining the aerodynamic shape of the rim and its race-tested advantages (less subject to crosswinds and enhances precise steering). A 16-spoke front wheel with an oversize 15mm aluminum axle helps counter the flex that occurs in contemporary super-light fork designs. The 20-spoke rear wheel, centered on a lighter weight aluminum freehub body creates the delicate balance -- so crucial to acceleration and speed -- between light weight and rigidity. The WH-7800 has the feel and speed of a super-light tubular carbon wheel, yet less subject to treacherous crosswinds and taking on the most challenging turns, even in the drops or the aero-bar. 10-speed compatible only.
