When the trail narrows and traction matters, the Bola 27.5" Superlight Carbon MTB Rim is built to help you accelerate, corner and recover faster. Optimized for trail, cyclocross and all-mountain use, this rim's combination of ultra-low mass and a wide 30mm inner profile improves tire support and responsiveness where grip and confidence count.

27.5" Superlight Carbon MTB Rim, 30mm Inner - Designed for trail, cyclocross, and all mountain riding

The rim's 370g (±10g) superlight build reduces rotational weight to sharpen acceleration and handling on technical terrain, while the 30mm inner width increases tire air volume for improved contact and stability. Its U-channel profile and 30mm height are compatible with tubeless setups and a range of tire sizes, delivering a balance of agility and control across diverse conditions.

Riders will notice a more composed feel in corners and better traction on loose or off-camber surfaces thanks to the wider bead seat and optimized tire shape. The rim's disc-only design and robust strength ratings allow confident riding when pushing speed or negotiating rough features.

Why it fits your routine

• Lightweight performance: Superlight 370g (±10g) construction lowers rotational mass for faster accelerations and more responsive handling.
• Wide profile for traction: 30mm inner width supports 2.25"–2.6" MTB tires and 35–42mm cyclocross tires to increase contact patch and cornering stability.
• Tubeless-ready: Hookless-compatible U-channel profile supports tubeless setups (recommended 45–65 psi) for improved puncture resistance and ride comfort.
• Strength & durability: Compressive strength >300kg and lateral torsion >50kg provide robust resistance to impacts and torsional loads common on trails.
• Materials: High-modulus carbon fiber (T700/T800 equivalent) offers a favorable strength-to-weight ratio.
• Compatibility: Designed for 27.5" (650b) wheel builds with an ERD of 540mm and disc-specific brake systems.
• Tested & certified: ISO4210 and EN14766 material tests, 100% ultrasound and dynamic stress QC testing ensure consistent quality.
• Warranty: 3-year manufacturing defect warranty provides manufacturer-backed coverage for typical service life concerns.
• Rider limit: Manufacturer testing recommends up to 100kg maximum rider weight.

Technical riders and competitive teams specify this rim for its blend of low weight, wide bead support and proven testing standards, making it a focused choice for riders who prioritize traction, responsiveness and reliable structural performance on varied off-road courses.
