MTB Carbon Rims

Bola Carbon Mountain Bike Rims (29er & 27.5")

Engineered for high-impact durability and razor-sharp handling, Bola carbon MTB rims cover every off-road discipline from lightweight cross-country climbing to World Cup downhill lines. Featuring precision hookless bead walls, asymmetric spoke triangulation, and wave profile geometries, these rims optimize modern 2.2"–2.6" tubeless tire casings for maximum traction at lower pressures (20–30 PSI).

Engineering & Manufacturing Highlights

  • Reinforced Hookless Sidewalls: Up to 3.5mm bead lips absorb rock strikes, eliminate pinch flats, and provide seamless tubeless tire seating.
  • Asymmetric Spoke Bed Offsets: Offsets spoke drilling up to 3mm to equalize drive and non-drive spoke tension, building stiffer wheels that stay true longer.
  • Modern Inner Channels (27mm–34mm): Cradles 2.2"–2.6" tires with a wider contact patch, preventing tire squirm during aggressive cornering.
  • Toray High-Modulus Carbon Fiber: Hand-laid Toray T700 and T800 unidirectional carbon matrix with CNC directional spoke-hole drilling.
  • Global Warranty & Service: Backed by Bola’s 3-Year Global Warranty, 30% Crash Replacement Discount, and Free Worldwide DDP Shipping.
