The Reserve 30|SL AL Rim brings the performance and design excellence of Reserve's highly-regarded carbon wheels to a more accessible high-performance aluminium package.
Designed for Cross-Country (XC), Trail, and All-Mountain riding, this rim offers a fantastic blend of low weight and robust durability for the custom wheel builder.
The 'SL' (Super Light) designation reflects its weight-conscious construction, utilising 6069 alloy to minimise mass while maintaining Reserve's renowned strength. The 30mm internal width is perfectly optimised for modern trail tyres (from 2.2" to 2.5"), providing excellent support, tyre profile, and enhanced traction.
Build your dream custom wheelset with the Asymmetrical Rim Design, which improves bracing angles and equalises spoke tension for a stiffer, stronger, and more reliable wheel build. As a testament to its quality and durability, the rim is backed by Reserve's industry-leading, transferable Lifetime Guarantee against damage while riding, giving you complete confidence to push your limits.
