CARBON RIM M3030 ( 29" )

The ROLLCii M3030 is a lightweight carbon rim built for modern trail and enduro riding. Designed around high-volume mountain bike tires, it delivers the stability, support, and durability needed for demanding terrain while maintaining a responsive ride feel on climbs and flowing trails.

Constructed from T24/T30 unidirectional carbon fiber with reinforced spoke hole construction, the M3030 balances low weight with the strength required for aggressive riding. The wide 36mm external width and 30mm internal width provide excellent tire support, helping larger tires maintain a stable profile through corners, rough sections, and technical terrain.

Whether you're building a lightweight trail bike, an aggressive downcountry machine, or a capable enduro wheelset, the M3030 is designed to offer predictable handling and reliable performance across a wide range of riding conditions.

Tubeless-ready and compatible with both tubeless and clincher tires, the M3030 works especially well with modern 2.4"–2.6" mountain bike tires, providing the support and confidence needed when trails become rough and demanding.

Designed to work naturally with modern 2.4"–2.6" mountain bike tires.
