Frequently asked questions
Can I easily install tire inserts like Cush Core?
Absolutely. The AR Offset rims are designed to be user-friendly, and riders have reported trouble-free installation of tire inserts like Cush Core, allowing you to enhance your ride quality and puncture protection without a hassle.
What spoke count do these rims support?
These rims are designed to support a 32-spoke count, providing a strong and reliable wheel build for various mountain biking needs.
What diameter and width options are available?
The Race Face AR Offset Rim is designed to be versatile, offering a variety of configurations to suit different riding styles and tire preferences:
- Diameters: Available in both 27.5” and 29” versions.
- Internal Rim Widths: Offered in 25 mm, 30 mm, 35 mm, and 40 mm options.
All models feature a robust 32-spoke count and a high-performance asymmetrical profile, which helps improve spoke tension balance for a stiffer, more responsive wheel build. Regardless of the size you choose, you benefit from their impact-resistant 6061 aluminum construction and a reliable, tubeless-ready design.
Is the asymmetrical profile purely for weight savings?
Not just for weight—the new asymmetrical profile is primarily engineered to provide optimal spoke tension balance. This results in a wheel that is laterally stiffer and more durable, giving you a more responsive feel on the trail.
Where can I find the correct ERD for my build?
Because the Effective Rim Diameter (ERD) can vary by specific model and production batch, it is essential to verify your exact measurements before purchasing spokes. Please consult the official Race Face Rim Dimensions Sheet to ensure you have the precise data for the specific diameter and width you selected.
Does the asymmetrical design improve stiffness?
Yes, the asymmetrical profile is a fundamental design feature engineered to significantly enhance the rim’s structural integrity and performance. This offset geometry ensures the rim is:
- Stiffer and Stronger: Built from durable 6061 Aluminum with improved extrusion for superior resistance against hard impacts.
- Optimally Balanced: The asymmetrical profile helps equalize spoke tension between the drive and non-drive sides, resulting in a more stable, durable, and balanced wheel.
