FAQ

Which freehub body should I choose?

It depends on your drivetrain. Choose Shimano HG if you're running an 11-speed Shimano or compatible road/gravel groupset. Choose Shimano Microspline if you have a 12-speed Shimano groupset (such as GRX 12-speed). Choose SRAM XDR if you're running a SRAM 12-speed road or gravel drivetrain (such as SRAM Rival, Force, or Red AXS). If you're unsure, check your cassette's compatibility specs or contact us before ordering.

What is the difference between the ROL CLD and White Industries hub options?

The ROL CLD hub is ROL's own precision hub, offering great performance and reliability at a lower price point. The White Industries hub is a premium upgrade - made in California, fully serviceable, and widely regarded as one of the best hubs available for long-term durability and engagement quality. If you plan to ride these wheels hard for years and want the best possible hub internals, the White Industries option is worth the upgrade.

What does "Wide" mean in the GP 45W (Wide) Carbon name?

The "Wide" designation refers to the internal and external width of the carbon rim. A wider rim supports modern high-volume tires more effectively, improving the tire's shape, contact patch, and overall performance. This is especially beneficial for gravel riding, where tire volume and stability are critical on loose or rough terrain.

Can I use a non-standard axle with this wheelset?

Yes. If your bike uses an axle standard other than the listed 12x100mm front / 12x142mm rear, simply select "Other Axle" when configuring your order. The ROL team will reach out to confirm the specifics before building your wheels.

Are these wheels tubeless compatible?

The product listing does not explicitly state tubeless compatibility. We recommend contacting us before purchasing if tubeless setup is a requirement for your build, so we can confirm current specs directly with the manufacturer.
