TECH

As one of our widest road rims designs, the WR45 is the answer for the gravel rider trying to squeeze out every aerodynamic advantage from their setup.

Designed with racing in mind, the WR45 features a deep U-shape profile that cuts through crosswinds and decreases lateral resistance. With a 45mm deep and stiff profile, the WR45 is designed for experienced bike handlers looking for an aero edge or larger riders.

Camilo : Both bikes feature a WR rim, one with 45mm depth and the other 65mm. Awesome handling in crosswinds due to the ultra wide rim profile and the 25mm internal makes the wheels very comfortable.

Tomas : I have been researching a carbon wheelset for 2 years until I finally pulled a trigger on these WR45. Since my frame can take up to 35mm tires, 32mm external width is a great way to future-proof your bike. The bike feels way different compared to alloy wheels, it accelerates way faster, it holds its line when descending and honestly looks way cooler. It is though sensitive to wind but still very bearable. I would not recommend pairing it with 28mm tire. GP5000s were really hard to mount and I had to use tire levers. I have just switched to 32mm and it is way different story, no levers needed. Huge benefit is being able to customize these wheels with spokes and hubs, I opted for dt swiss 240exp and sapim cx rays for wide availability of spare parts. Customer service was flawless and wheels arrived approx. 4 weeks after placing the order.

Daniel : I recently added the WR45 Wheels to my Cannondale SuperX - fantastic set of wheels and great value. I weigh almost 100kg and take this bike most places including some great MTB trails in Singapore - overall I highly recommend it! I am about to order a second pair so I can set it up for road rides.

Miguel : The wheels are built like a tank. They're light and stiff, but can take a great deal of beating. I'm sure I'll have them for a long time. :)

Hi there! For the WR45, would you be able to specify the diameter of the spoke nipple access holes, at the rim bed? The ones that get covered by rim tape. Thanks!


LightBicycle 2022/12/12

Hi Nick, The spoke access holes are 8mm for standard 14G spokes and nipple wrench. Is there a reason why you like to know about this? We can customize the diameter if you request it. Thanks, Lightbicycle

Hi, Just wondering the advantages of the hookless version of your WR45 disc rims? I am 73kg and looking at the flyweight rims and wondering if the hookless rim would be stronger? Thanks


LightBicycle 2022/03/08

Hi Sir, - Hooks provide more stability and tire retention, especially at higher tire pressures. There's no obvious difference in strength for hook and hookless. For road rims, vertical strength is the main factor in your riding experience. Given the fact that the rim depth is the same. The vertical stiffness/strength is the same. - If you are running wider tires, lower pressures, or are riding on rougher roads, you may be a good candidate for hookless 700C road disc. You will benefit from a more comfortable ride due to the higher volume and increased impact protection. Gravel riders and cyclocross riders are often in this situation. But it has a tire pressure limit. If you want to run more than 70psi. I would recommend hook rims for safety concerns. Thanks, Lightbicycle

How stable are those rims in high speed descents and windy conditions? Planning on upgrading from 30mm deep to this one and wondering what the difference will be. Thanks!


LightBicycle 2021/06/15

Hi Paolo, The 700C rim disc shape design of WR45-32mm wide/45mm deep performs very well on both crosswinds and in no wind conditions. The stability depends on many things like rim design, speed. yaw angle, etc. So not sure what's the current rim you are using at the moment. Thanks, Lightbicycle

Hello, is there a reason why the WR rims (including the WR45) do not have an asymmetrical profile? (As you probably know, the asymmetry offers the advantage of more even spoke tensions.) Thanks


LightBicycle 2020/12/02

Hi Julian, The main reason why we don't make an asymmetric version of WR rims wide 700C road is out of aerodynamics consideration. A symmetrical rim would gain more aero benefits. Thanks, Lightbicycle

Hi there. does the hookless variant of this rim comply with the new ETRTO standard? specifically the dimension of the bead seat diameter?


LightBicycle 2020/11/17

Hi Tom, For hook and hookless, they share the same rim mold. So, the ETRTO is the same on these WR45 road disc rims. Thanks, Lightbicycle

As a 15yo 65kg road and cross rider trying to build a super light aero wheelset do you think the flyweights would be strong enough? Thanks


LightBicycle 2020/03/26

Hi Matthew, The WR45 road disc rim with flightweight version is strong enough for 65KG rider.Do you like rims only or complete wheelset 700C? Thanks, Lightbicycle
