The 3T Mercurio 40 LTD Carbon Tubular Rear Wheel is a medium-low profile race wheel in 3T's flagship Mercurio tubular range. Deploying the full range of 3T's new-generation technologies, it is ultra-light, spins up quickly, rolls fast, and brakes hard in wet or dry. The all carbon fibre rim is 43 mm deep x 23 mm wide, and has spoke pockets moulded in to the rim sidewall to capture the non-nipple end of the straight Sapim CX -Ray spokes. By putting the nipples at the hub end cuts inertia at the rim, so you can accelerate faster. The rear hub supports Campagnolo 10/11 speed, Shimano 10/11 speed, and SRAM cassettes by using a Multisys freehub body. This 3T Wheel is supplied with custom brake pads made by SwissStop.
