Lún HYPER
Wheels
The reviewer tested the Lún HYPER wheels, which are Windspace D45 wheels, on a mountain climb and descent. He found them to be noticeably stiffer than previous wheels, which improved climbing performance, and he set personal records on several segments despite not pacing perfectly. However, he felt less confident during cornering on the descent due to the wider internal width stretching his tires, and he noted a ringing sound from the carbon spokes when braking. Overall, he considers them high-quality and good value for the price.
AI Summary
Pros
- The wheels are noticeably stiffer, feeling like one solid piece of carbon fiber, which improves responsiveness and climbing ability.
- The stiffness made steep sections and switchbacks feel easier to handle.
- The reviewer set personal records on several climbing segments despite lower power output and not being fully fresh.
more pros in the video
Cons
- The wider internal width stretched his Continental GP5000 tubeless tires, making him feel less planted and confident in corners during the descent.
- The carbon spokes produce a ringing sound when braking, which he noted but did not find bothersome.
- He was skittish on the descent because the wheels were new and he didn't know their limits, so he didn't take risks and was slower than on his previous wheels.
more cons in the video
Key Points
- The wheels are Windspace D45, with a depth of 45mm (though he mentions 55-40-46, likely a misstatement) and a 21mm internal width.
