BOLA 32er Asymmetric Carbon MTB Rim — 30mm Inner Width, 30mm Height, Tubeless-Ready (696mm BSD)

Take a confident line on steep, technical trail sections or push harder on big-feature enduro tracks with a rim engineered to balance strength, tire support, and modern tubeless performance. The BOLA 32er Asymmetric Carbon MTB Rim is purpose-built for 32-inch (696mm BSD) wheel platforms used in aggressive trail, enduro, and freeride riding, offering two carbon layup options so builders can prioritize lower weight or greater durability.

BOLA 32er Asymmetric Carbon MTB Rim - Designed for trail, enduro and freeride

Riding with predictable handling and secure tire seating changes how a bike feels under load: the asymmetric U-shaped profile and 30mm inner width improve tire support across the contact patch while the 30mm rim height contributes to overall wheel stiffness. The rim’s hookless, tubeless-ready architecture lets you run lower pressures for traction and compliance without sacrificing sidewall protection when the terrain gets rough.

Why it fits your routine

• Optimized tire pairing: Engineered for 2.3–2.8" mountain bike tires so you can spec wider rubber for traction on loose or rocky lines while maintaining stable sidewall support.
• 32er compatibility: Built for 32-inch (696mm BSD) wheels and compatible 29+ setups, giving riders who prefer larger wheel platforms a dedicated rim shape and fitment.
• Lightweight or robust layups: Two carbon layup choices—superlight at 350g or standard at 450g—allow custom builders to select a balance between minimal rotating weight and added strength depending on riding style.
• Asymmetric U-shaped profile: Improves rim stiffness and tire seating symmetry for more predictable cornering and consistent tire contact across varied terrain.
• Tubeless-ready, hookless design: Supports modern tubeless tires and allows lower inflation pressures for better grip, while the profile reduces the chance of pinch flats during aggressive hits.
• Proven strength and quality control: Each rim undergoes forward compressive strength testing to greater than 300kg, spoke tension validation above 280kg, flatness tolerance under 0.15mm, and dynamic balance within 3g deviation per unit to ensure consistent performance.
• Builder- and OEM-friendly: Available for custom and OEM spoke counts, layup weights, and finish options so wheelbuilders and manufacturers can tailor wheels to specific hub standards and riding demands.
• Warranty coverage: Backed by a 3-year limited warranty covering structural defects under normal riding conditions as detailed in BOLA’s warranty policy.

Compared with common competitor rims, the BOLA 32er delivers a 30mm inner width and 30mm rim height on a 696mm BSD platform, with Toray-grade UD plus woven carbon construction and tested maximum compressive strength exceeding 300kg while offering lighter weight options than many typical carbon MTB rims. These characteristics make the rim an option for riders and builders seeking larger-diameter, high-strength carbon rims for demanding trail, enduro, and freeride applications.
