The Lún HYPER D45 are our best all-round disc-brake wheels. Carbon spokes, ceramic bearings and a filament-wound rim make them the ultimate performance wheelset. The super-lightweight construction makes them climb and accelerate like no other wheel. Carbon spokes produce a wheel that is both light and stiff giving you wheels you can rely on for the hardest sprints or toughest climbs, day-in, day-out.

Wider Range
In reviews and comments alike, the same few comments kept coming up. “I wish there was an even shallower option.” said the climbers. “I wish there was a deeper option.” bemoaned the speed lovers. We listened. The shallowest wheel is now shallower than ever (35mm), and the deepest is deeper than ever (68mm!)

Stability Meets Speed

F-RAPID Design
The R33 and D33 wheels are designed for all-out climbing performance. However, our 45 and 67 series wheels put aerodynamic efficiency first. They’re the first wheels to feature our F-RAPID Design. The Front and Rear Aero Profiles are Individually Designed to meet their unique demands. The front wheel is optimized for its leading edge performance giving speed and stability in a variety of conditions with a more rounded rim profile. The rear wheel profile is taller and is optimized for lower yaw angles with an emphasis on trailing edge performance.

28% Increase in Drive Spoke Angle
Spoke angle has a huge impact on the performance of a wheelset. While there’s no “perfect” angle, after feedback from our professional athletes and weekend warriors alike we increased the drive-spoke angle by 28% leading to greater torsional stiffness and more direct power transfer. This led to a 15.7% increase in torsional stiffness
