Reserve - 28 XC - 29" Carbon Rim

Reserve - 28 XC - 29" Carbon Rim

The Reserve 28|XC Carbon Fibre Rim is the foundation of a World Cup-winning wheelset, offered here for custom builders and riders looking to upgrade their existing hubs.

This ultralight rim is the culmination of years of elite-level competition data, engineered to be stiff, strong, and highly compliant where it matters most on modern Cross-Country and 'Downcountry' race tracks.

At a mere 385 g (nominal), this rim features a 28 mm internal width, providing optimal support for contemporary XC tyres (from 2.2" to 2.5"). This wide stance increases tyre volume and improves the tyre's profile, leading to enhanced stability and cornering grip at lower pressures. The innovative, shallower profile and Asymmetrical Design (with a 2.8 mm offset) are key to its strength, balancing spoke tension for a stiffer, more reliable build. At the same time, the low depth adds vertical compliance to absorb trail buzz.

Key design details include externally reinforced spoke holes and a redesigned 'Step-in' rim bed, which dramatically eases the notoriously fiddly process of tubeless tyre installation and ensures secure bead retention. When building your dream wheelset, you can rest assured knowing the Reserve 28|XC rim is backed by Reserve’s market-leading, transferable Lifetime Warranty with no rider weight limit. This rim is your starting point for a professional-grade, custom-built wheel.
