Race Face ARC Offset Rim

The asymmetrical design offsets the nipple bed, which allows for more balanced spoke tension between the drive and non-drive sides of the wheel. This results in a stiffer, stronger wheel build that holds its true shape better under heavy riding loads.

Yes, the ARC Offset is built from 6069 aluminum, which provides the high strength-to-weight ratio necessary to handle the increased torque and weight demands of modern eMTB riding.

While the rim features a tubeless-ready profile designed for easy, reliable tubeless setups, it is fully compatible with standard inner tubes if you prefer that setup.

The 40mm internal width is quite wide, making it ideal for high-volume tires, typically ranging from 2.5 inches up to 3.0 inches, depending on your preferred tire profile and clearance.

Because of the asymmetrical drilling, you should ensure your wheel builder is aware of the offset to select the correct spoke lengths. Standard J-bend or straight-pull spokes work fine, but precise measurement is key for a proper build.

No, this rim is designed exclusively for disc brake systems. It does not have a machined braking surface on the sidewall.
