Bola 700C Carbon Road Rim for Disc Brake — 28mm Wide, 45mm or 50mm Depth, 20/24-Spoke, Tubeless Ready

Ride with confidence on varied courses: these Bola 700C carbon road rims are built for disc-brake road bikes that demand a blend of aerodynamics, tire support, and strength. Choose 45mm for greater crosswind stability and climbing versatility or 50mm for maximized aero performance on flat and rolling roads. Available in multiple weight tiers, these rims suit racers chasing every gram as well as riders prioritizing durability.

Bola 700C Carbon Road Rim - Designed for high-performance road and endurance riding

The broad 28mm outer / 22mm internal U-shaped profile improves tire support and handling when paired with recommended 28–32mm tires, while tubeless-ready compatibility reduces pinch-flat risk and allows lower pressures for greater comfort. Constructed from high-modulus Toray-grade carbon with UD and woven layup options, the rim delivers the stiffness needed for responsive accelerations and the compliance that benefits long efforts.

Why it fits your routine

• Tailored aero vs stability: 45mm depth balances aerodynamic gain with better crosswind control for climbing and mixed terrain, while 50mm depth prioritizes aerodynamic efficiency for flat and rolling courses.
• Multiple weight tiers: Choose from Extreme Light (from 360g) through 380g, 410g, to 440g to match racing ambitions or daily durability needs, with ±15g manufacturing tolerance.
• Disc-specific construction: Designed exclusively for disc brake systems, removing brake-track compromises and optimizing rim shape for contemporary road disc frames and brake calipers.
• Tubeless ready and tire support: 22mm internal width and tubeless compatibility support 28–32mm tires for improved ride comfort, rolling resistance, and puncture protection.
• Spoke and hub compatibility: Available in 20 or 24 spoke drillings to suit lightweight race wheels or stiffer endurance builds and compatible with standard 24-hole disc hubs.
• Proven strength tolerances: Engineered and tested to industry tolerances including >300kg compressive strength, >280kg spoke tension, <0.3mm roundness, and <0.15mm flatness.
• Practical specifications: ISO 622 (700C), standard 6.5mm valve hole (custom options available), and recommended tire pressures between 100–125 psi within the stated rider weight limits.

Application and compatibility are explicit: these rims are intended for competitive racing, endurance rides, and bespoke OEM wheel builds on 700C disc brake road bikes using tubeless or clincher tires 28–32mm wide. Maximum rider weight is specified at 120 kg, and the rims are manufactured to documented testing tolerances that support reliable performance under load. Whether you specify a lighter 360g rim for race day or a heavier 440g rim for everyday resilience, the Bola design prioritizes tire support, consistent roundness, and spoke tension capacity to maintain wheel integrity over time.
