The 45 Disc Carbon Clinchers


Clear selection

More than just a one-hit wonder, The 45 Disc carbon clinchers are a perfect mid-depth, lightweight carbon tubeless-ready rim with a modern, 21mm internal rim width. We designed the rim specifically for use with a disc brake, which allows us to truly maximize wheel performance without having to consider design elements specific to rim brakes. The 45mm rim depth blends light weight with aerodynamics for a balanced approach to your faster-paced rides. This makes them ideal for all road rides and races, as well as for gravel rides at higher speeds, where aerodynamics play more of a factor. Thanks to HiFi’s Anti-Flutter technology and toroidal rim shape, crosswinds have a less of an impact, and you’ll be even faster at a larger range of wind yaw angles.

Fidelity R36 Hubs

The 45 Anti-Flutter Disc wheel sets spin on the latest iteration of our Fidelity R36 Disc centerlock hubs, which use a 4-pawl system engaging with a 36-tooth ring. The R36 Disc hubs offer quick and reliable engagement, light weight, and dependability. They’re also easy to service when the need arises, with bearings that are easy to access and no proprietary tools required. We lace up The 45s with top-tier Sapim bladed spokes for their ideal blend of lightweight, aerodynamics, high strength, and sublime ride quality.
