Description

Our new rim brake specific The 45 SL carbon clinchers hit the sweet spot for those looking for a wheel that blends light weight with some significant aerodynamic advantages. They build into a lightweight carbon tubeless-ready wheel set with a modern, 19mm internal rim width. For the rim brake specific The 45 SL design, we of course prioritize the heat dissipation and braking performance at the brake track. Braking is excellent with the HiFi Stellar carbon brake pads, as well as other popular aftermarket carbon pads. But The 45 SLs aren’t about slowing down; they’re about cranking up the pace! The light weight, mid-depth carbon rims will spin up to speed super quickly and their aerodynamics will help you stay there with less effort. 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. The extremely high-grade carbon fiber we use is stiff for accelerations but is also good at dampening bumps and chatter.

Fidelity R36 SL hubs

The 45 SL Anti-Flutter wheel sets spin on the latest iteration of our Fidelity R36SL non-disc hubs, which use a 4-pawl system engaging with a 36-tooth ring. The R36SL 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.
