The Lún HYPER D33 are our best climbing 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.

In late 2019 Winspace debuted Lún HYPER wheels to great fanfare. It seemed we’d cracked the code on what road cyclists wanted in a wheelset: Fast, light, stiff and a characteristic snappy acceleration like no other wheel out there. The word spread, so we built more…and more, and more. 50,000 wheels later and Lún HYPER wheels were being ridden in over 75 countries on six continents. They rode people to personal bests, KOMs, podiums, and state and national championships.
We didn’t rest on our laurels. We knew we had a challenge ahead of us: How do you improve on the greatest? We quadrupled our R&D budget, got some of the greatest minds in the industry and custom-built a plethora of wheel-testing lab equipment. However, in addition to these, we had one ace up our sleeves: You.
The feedback from our customers was invaluable. You people know bikes, and you know exactly what you want from a wheelset. Every YouTube review, every forum post, every Instagram hash-tag, every comment… we read them all. The consensus was clear. People wanted a wider rim; that was easy enough. But people also wanted Lighter, Stiffer, and Faster. That got the engineers scratching their heads. They rose to the challenge and came back with a series of wheels that is on average 15% Stiffer, 6% Lighter and ready to make you faster.
21mm Internal Rim Width
The optimum rim width for different yaw angles and riding speeds can be debated. However, one thing that was overwhelmingly clear was that you guys wanted a wider internal rim width for riding with wider tires. The wider 21mm internal width rim gives a better aerodynamic performance with a 25mm wide tire compared to our previous model Lún HYPER due to the better transition from the tire to the rim. 21mm internal rim width is perfect for either 25mm or 28mm tires but can take tires all the way up to 47mm.
Stability Meets Speed
The R33 and D33 wheels are designed for all-out climbing performance. However, The Lun 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.
Every Gram Counts
While most the improvements for Lún HYPER 2023 are incremental, they add up to measurable gains. In a sport where sprints are won or lost by fractions of an inch, every gram, every millimeter, every small detail makes a difference. It took us countless carbon layup iterations to hit our weight and strength targets but the results were worth it. On average we shaved over 50g from each wheelset compared to the wheelset it replaces.

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)
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.
Rim or Disc:
The choice is yours
Race-day Performance Every Day
When updating the Lún HYPER wheels to 2023 spec it was important to retain the essence of what made the Lún HYPERs hyper. The Lún HYPERs is known for bringing huge performance to an affordable price point, and that didn’t change.
We kept the filament-wound rim to keep the weight down and the acceleration fast. The butterfly weave finish reinforces the rim at the spokes while keeping weight down across the entire rim.
The carbon spokes remain an essential part of the formula. Carbon spokes are lighter and stronger than their traditional steel counterparts and offer great ride characteristics of snappy acceleration and greater wheel stiffness during sprints.
We’re Hooked on Tubeless
We think tubeless is great, but if you’re not convinced we still support regular clincher tires and tubes. For those running tubeless we made small tweaks to the rim which should make the tubeless setup just that little bit easier.
The hub is the heart of any wheelset. It can make or break the best of designs. The Lún HYPER 2023 hub’s internals remains mostly unchanged: A strong over-sized 17mm axle is able to cope with the forces of any sprint effort. Large 6903 and 6803 bearings placed in reinforced bearing seats help improve bearing life and lower rolling resistance.
Tested by Pros, Approved by the UCI
Pro cyclists are the ultimate test for bike equipment. They only want the best performance, and they demand reliability. All our new products are tested extensively in both lab conditions and out in the real world.
