700c, 27-Inch & 650c

The 1/Fifty is a wide, deep profile, full carbon aero rim that successfully blends crosswind stability, stiffness and handling while delivering superior heat dissipation and braking performance by utilizing the same ultra high Tg resin and brake pads as the TwentyFour series wheels. The semi-automated carbon lay-up, rim construction and raw materials proven through the TwentyFour series wheels are exemplified in the 1/Fifty rims. By utilizing components optimized for more efficient production, we are able to deliver a performance wheelset at an aggressive price.

Get some extra speed in criteriums, time trials, and triathlons on Profile's 38/TwentyFour wheels. Their 38mm-deep carbon rims slice through the wind, yet are not so deep that they get pushed around in crosswinds. For extra stiffness, hi-flange hubs are paired with handbuilt construction, and bladed spokes.

There are no compromises on race day, and Profile Design knew that when they designed their 58/TwentyFour tubular wheels. The 58mm-deep rim, 24.5mm rim width, and super stiff carbin layup provide uncompromising go-fast performance. And, the aero shape of the rim slips easily through the breeze, increasing your efficiency and speed. Match these rims up with your favorite tubular tires (sold separately) and experience a ride that clinchers just can't offer, with high-traction cornering and a supple road feel you need to ride to believe. The hubs feature sealed bearings for high-mileage durability and the freehub body is Shimano/SRAM 9, 10, and 11-speed compatible so you can use the drivetrain of your choice.
