Introducing the UFO-C21 Full Disc Wheel: Ready to Attack the Course

Updated (2022/03/17) - 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 newer version is more scratch-resistant while being lightweight.

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 1000 grams, which is ~100 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.

Hi Lightbicycle team! I am interested in your rear disc wheel for my previous generation trek speed concept rim brake (the most recent one before they switched to disc this year). I was wondering if the disc will have enough clearance for my rear chain stays. I believe it known to be tight because of the built in doutrap in the non drive side. for reference I have an older generation Zipp tubular disc which fits fine right now. Thanks for the help.

Hi Joe, Thanks for your inquiry! The UFO full disc wheel 700C is 28mm wide. Is it your bike wide enough for 28mm wide? Or you can check with your bike supplier whether your bike is wide enough. If not, we also have 25mm rear full disc wheel. We are on Chinese New Year vacation from Jan 29th~ Feb 7th, will be back to work on Feb 8th. I can send you more specs of 25mm wide wheel if you like. Thanks, Lightbicycle
