At only 475g with an aerodynamic 45mm deep profile, the U45 is our jack-of-all-trades rim. Whether you are chasing KOMs on the mountain or racing your buddies to the next checkpoint, this wheel is for you.
With a 45mm depth, this wheel offers all the aerodynamic benefits of a much deeper profile in a lighter package that’s easier to control in crosswinds. If there’s climbing to do, these could be your best choice.

WHAT IS IN THE BOX
Florian: After a life on alloy wheels, I finally decided to upgrade to carbon. After a long time researching the topic I luckily ended up getting Light Bicycle wheels. The order process was super smooth with lots of customizing options. Support thereafter was amazing and the manufacturing and building process was 100% transparent. Even more importantly, the quality of the wheels is superb and it's pure joy riding them! Thanks Light Bicycle family!!!
Tim: R45 - light, aero, fast
Mohsin: R45 wheelset. This is my second purchase from LB. I'm very happy with the wheels as well as the helpful service I received from everyone at LB.
Les: Excellent wheel set. Quick shipping. When I took them out of the box I was amazed at the quality of the build. Used the Bitex hub configuration and they spin forever. I can definitely notice an increase in speed over my stock wheels.
Sam: There's a common theme across all my bikes... They all roll on Lightbicycle Wheels, quite simply the best value performance wheels on the planet.

I'd recommend Lightbicycle to anyone based on that experience and the quality of the rims!
