Updated (August 2022) - We have upgraded the UFO-C21 full disc from non-pro to pro series to make it more capable of tackling the challenges in training and racing. The latest version is ultra-lightweight - the carbon structure (without hub) weighs only 840g, achieving a weight loss of 160g. The complete wheel comes in at an astonishingly low weight of sub-1100g.
Bring your aero bike to a new level with our full disc wheel! The UFO disc wheel fills the gap in our aero-optimized products with a new Tri/Track specific wheel. Let’s learn more about this speed weapon.
An aero upgrade under $1000
Disc wheels offer unparalleled aerodynamics with the spokeless design, which greatly reduces aero drag and turbulence. If you are a professional triathlete, track cyclist, or time trialist, disc wheels provide an obvious competitive edge.
Optimized for race performance, our UFO-C21 offers unbeatable value with our in-house engineering and direct-to-consumer model. This may be the most budget-friendly upgrade you can make to your aero bike in 2022.


What does it weigh?
Traditional disc wheels are usually much heavier and more expensive than spoked wheels, but the UFO full disc structure (excluding the hub) featuring paintless tech is down to 840 grams, which is ~250 grams lighter than competitive counterparts. How did we achieve this?
The UFO is made of equally sized high-quality T800 carbon and ultra-thin PMI foam plates. The high-density foam significantly reduces the risk of delamination while adding torsional and lateral stiffness which is required during high intensity sprints. The hollow construction also makes it easier to evacuate the air sneaking from the tire into the rim, increasing safety.


A modern disc wheel from every aspect
The UFO disc wheel is available in both disc brake-specific and rim brake track versions, at the same price.
The clincher disc wheel also keeps tubeless compatibility in mind, just like other clincher rims we offer. Its wide profile, 21mm inner 28mm outer, is suitable for 25c to 38c tires. The hooks provide excellent tire retention up to 130psi (based on a 25c tire). More comfort or more speed – the choice is yours.
The valve opening is equipped with a carbon cover to reduce turbulence and keep out debris. The UFO disc wheel is not only going to make you faster, but it will last for years.

Weave: UD & Sunflower
The UFO-C21 is available in two weave styles: UD (uni-directional) and “Sunflower”. The innovative Sunflower weave consists of twenty-three carbon strips per side, handcrafted by our most experienced layup technicians. Unlike many strip surfaces in the market, the Sunflower weave features continuous fibers from rim edge to edge, which adds to the strength of the wheel. The strips display a dynamic look, similar to spoked wheels in motion.
