Bola 700c Carbon Road Rim 45mm Profile — 34mm Outer, 28mm Inner, Tubeless Ready

Take on long days on pavement or stretch onto mixed surfaces with a rim built to balance aerodynamics, comfort, and modern tire volumes. The Bola 700c 45mm carbon rim supports 25–32mm tubeless tires and is engineered to deliver consistent builds and dependable performance for riders who mix endurance, racing, and gravel use. Precision manufacturing and verified weights across build grades make it straightforward for builders and teams to specify and trust.

Bola 700c 45mm Carbon Road Rim - Designed for road and gravel riders

The rim’s 34mm outer width and 28mm inner channel increase air volume and stabilize wider tires at lower pressures, which improves comfort and traction without sacrificing aerodynamic benefit. Disc-brake compatibility and a hooked U-profile provide compatibility with contemporary wheel builds and tubeless setups.

Why it fits your routine

• Versatile tire support: Engineered for 25–32mm road and gravel tires so you can run tubeless setups that favor lower pressures and better comfort.
• Balanced aero and control: The 45mm profile offers aerodynamic assistance on pavement while maintaining stability in crosswinds for mixed-terrain riding.
• Modern width for better handling: 34mm outer and 28mm inner widths support contemporary tire shapes for improved grip and rolling efficiency.
• Precision build quality: Verified rim weights by build grade (370–445g) and tight flatness and roundness tolerances (<0.15mm) reduce headaches during wheel building and promote long-term reliability.
• Wheelbuilder friendly: ERD 548mm, 6.5mm valve hole and 4.5mm spoke hole standard sizes are customizable to match hub and spoke choices for custom builds.
• Durability and compliance: Constructed from high-modulus carbon fiber with UV-cure resin and tested for forward compression >300kg, lateral torsion >50kg, and spoke tension >280kg.
• Disc-brake ready: Designed for disc-brake wheelsets to suit modern road and gravel bikes used in competition, training, or daily riding.
• Low dynamic imbalance: Dynamic balance <3g supports smooth high-speed rotation when correctly built and trued.
• Warranty: Covered by a 3-year warranty from purchase for manufacturing-related issues.
