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
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.
Victor: RRU45C02d 24H UD satin Without Holes hook Disc RRU45C02d 24H UD satin Without Holes hook Disc HUB-F DT SWISS 240 EXP 12 / 100mm straight pull Center lock Black 24H HUB-R DT SWISS 240 EXP 12 / 142mm Shimano Road 11S straight pull Center lock Black 24H EXP 36 SPOKE Black straight pull Sapim CX Ray NIPPLE Sapim Aluminium Black glossy black decals nonremovable The wheels are mounted on a Xelius SL Pro FDJ 2017, 7.0 kg with pedals, bottle cages etc. I exchanged my ultegra 37mm wheels for this incredible wheelset: my bike has been really transformed: not only it is lighter by 300g but the wheels are incredibly stiff and responsive, and I do feel the significant improvement in the flat of the 45 mm rims. I'd recommend Lightbicycle to anyone based on that experience and the quality of the rims!
Emacdo: Bought a set of 35MM and 45MM rim brake rims and built them up over the winter with a pair of Campy Electron hubs (completely rebuilt). The 35/45 configuration is a great all-rounder setup - climber in the front, aero in the back. They were fantastically easy to lace up due to their very tight construction tolerances. Finally have been able to take them on a couple of shorter rides in the last couple weeks (now that Spring is here where I live) and they were fabulous. Rode 90+ miles today on chip seal and washboard roads and the rims handled really well. These are now my favorite wheels. I can't say as much about the Conti 5k tires, but that has nothing to do with the rims (switching to a set of Vittoria Corsas after today's ride). The roads around here are passable at best, so I have done my best to beat these rims around and they have responded perfectly. I can't wait to put many more miles on them.
Roger: Rims: R45/R65 Mixed Combo Non-Disc Hubs: Acros Nineteen RD 24/32 Frame: VPACE T1R Titanium I ordered the rims separately according to my own wishes (3K twill vertical no decal) and built them by myself. The wheels perform very well under all conditions. It's always a pleasure to ride with them.
