overview

MERCURIO 40 LTD is a medium-low profile race wheel in 3T's flagship MERCURIO tubular range. Deploying the full range of 3T's new-generation technologies, this wheel is characterized by ultra-light weight, aerodynamic stability, and highly-effective, predictable braking in wet, dry, and transitional conditions. The wheel is immensely strong and rigid despite its relatively low profile (43 mm) and can be selected with confidence for general-purpose racing as well as climbing stages, to which it is particularly suited. Like other MERCURIO models, the innovative, all-carbon-fiber rim, 23 mm in width, has spoke pockets molded in to the rim sidewall to receive the non-nipple end of the straight Sapim CX-Ray spokes (18 front, 24 rear). The wheel's inverted-spoke design means nipples add no weight at the perimeter, promoting rapid spin-up. This design has the added convenience of making it possible to effect repairs to damaged spokes without removing the tubular tire. Hubs can be specified with ceramic bearings, and feature 3T-exclusive freewheel spline accepting both Campagnolo and Shimano/SRAM cassettes with no adapter.
