3T Mercurio 60 LTD Tubular Rear Wheel. Part of 3T's flagship Mercurio tubular range, the Mercurio 60 LTD rear wheel is a no holds barred medium deep aero race wheel optimized for speed, speed, and more speed. The 63mm deep all carbon fiber rim is not only stiff, aerodynamic, and feather light, but 3T's engineers have pushed the performance envelope with their unique spoke design. Spoke pockets are molded into the rim sidewall where the non nipple end is anchored, while the nipple end is placed at the hub. This design reduces the inertia of the rim which equates to better acceleration. The 24 Sapim CX Ray spokes themselves are aerodynamic, too, and perfect for achieving the high tension needed for a stiff, high performance wheel. The race ready package is topped off by 3T's titanium skewer that keeps the weight low plus a set of SwissStop brake pads that deliver stellar stopping power and wet or dry conditions. Pair this wheel with the 3T Mercurio 60 LTD Tubular Front Wheel YW M60F to complete the set.
