Race Face ARC Offset Rim

The asymmetric profile shifts the spoke holes slightly to one side, which helps equalize the spoke tension between the drive and non-drive sides of the wheel. This results in a stiffer, more durable wheel build that handles lateral forces better than a traditional symmetrical rim.

Yes, the ARC Offset is designed to handle the extra torque and weight of eMTBs. Its 6069 aluminum construction is specifically engineered for high-impact gravity riding, making it a robust choice for electric mountain bikes.

A 30mm internal width is widely considered the sweet spot for modern trail and enduro tires, typically ranging from 2.3 to 2.6 inches. This width provides a stable base that minimizes tire squirm during aggressive cornering without squaring off the tire profile.

Race Face offers a comprehensive lifetime warranty on this rim that explicitly includes damage sustained during crashes. It is designed to give you peace of mind when pushing your limits on technical terrain.

The rim features a robust bead profile designed for standard tubeless tape and valves. While any high-quality tubeless rim tape will work, ensure you use a width that matches the 30mm internal dimension for the best seal.

While these rims are built for gravity and enduro, they are surprisingly efficient due to the high-strength 6069 alloy. However, if you are strictly focused on lightweight XC racing, you might find lighter, less robust options better suited to your needs.
