Reserve 34|37 SL Tune Hubs - Carbon Spoke Road Wheelset - Shimano HG + XDR Freehubs incl

New | The Climber's Wheelset

Thanks to the latest advancements in our carbon layup process, 34|37 SL wheels are lighter than ever without sacrificing any strength. Designed for Team Visma Lease-a-Bike, these wheels are made to lead the peloton up the world’s steepest, most unrelenting climbs.

Made for efforts like Jonas Vingegaard’s assault on Bola del Mundo in the 2025 Vuelta a España.

Our SL wheels come with carbon spokes and are only available together with our lightest hubsets.
