A fast time trial wheelset seamlessly integrates aerodynamics, weight optimization, power transfer efficiency and stability to help riders achieve their fastest times against the clock. 2024 is going to be the year of the time trial, as many of the major tours and Olympic gold will be decided in these individual efforts. Reserve paved its way into the Pro Tour with one of the fastest time-trial wheelsets ever designed in the 77|Disc, and it was used by Team Visma – Lease a Bike’s Jonas Vingegaard in both 2022 and 2023 to win the most famous races on the calendar, the Tour de France.

Mixed Profile

The mixed depth front and rear of the 77|Infinity Disc is designed to provide a perfect balance between stability and aerodynamics. A lower profile front reduces reaction to cross winds, while the disc minimizes drag.

Race tested at the highest levels of competition: Team Jumbo Visma's Wout van Aert wins Stage 20 of the Tour de France on the Reserve 77|Disc wheelset and Yellow Jersey holder Jonas Vingegaard finishes 2nd.

Bonded Rear Hub

The Infinity Disc rear wheel is disc-brake only, with a bonded-in rear hub, that is available for either SRAM XDR or Shimano HG drivers. Both front and rear are 22 inner width, designed for use with tires up to 28c.

FAQ

What is the maximum pressure for your rims?

Road rims: 100 psi (6.9 bar). Gravel rims: 80 psi (5.5 bar).

Always defer to the tyre manufacturer's stated maximum if it is lower than the rim's — the lower of the two figures is the one to run.

Can you build me a wheelset if I send you my hubs? Do you sell rim-only?

Yes. We offer a full wheelbuilding service at Legend Bikes — send us your hubs, or choose hubs with us, and our workshop will build them to your Reserve rims. We also sell rim-only options if you'd prefer to have the wheels built elsewhere. Get in touch and we'll talk through spoke count, lacing and hub compatibility for your bike.

Where can I find more tech spec information?

The full technical specification for this wheel — ERD, rim widths, spoke count, hub spacing, freehub and rotor options — is listed in the Details section further down this page. If you need a figure that isn't there, contact us and we'll get it for you.
