Bola 700c 50mm Carbon Road Rim, 23mm Inner Width, Tubeless Ready, Disc Brake Compatible

On fast group rides, long gran fondos or a focused hill session, the Bola 700c 50mm carbon rim lets you combine stability, aerodynamic benefit and tubeless-ready versatility. Built with a 23mm inner width and a deep 50mm profile, these rims are designed to perform across training, club racing and endurance events while supporting customizable builds for professional teams and OEM applications.

Bola 700c 50mm Carbon Road Rim - Designed for road racing, endurance and training

The 50mm profile (30–34mm outer width depending on configuration) balances aerodynamic efficiency with crosswind stability. With a hookless-compatible UV rim shape and a 6.5mm valve hole (customizable), the rim is tubeless-ready when paired with appropriate rim tape and tubeless valves. Disc-brake-only construction eliminates a machined braking surface and focuses material and layup where it improves stiffness and ride quality.

Riders will notice a confident feel on sustained efforts and improved tire support for wider road tires; the rim’s 23mm internal width supports recommended tire widths of 25–32mm and suits the trend toward broader, lower-pressure road setups while meeting structural testing standards for robustness and reliability.

Why it fits your routine

• Versatile sizing: 700c (ISO 622mm BSD) with 50mm profile and 23mm inner width supports 25–32mm tires for training, racing, and endurance riding.
• Tubeless-ready: Designed for tubeless setups using compatible tape and 6.5mm valves; rated tire pressure range is 100–125 psi for clincher specification while tubeless setups typically run lower pressures per tire guidance.
• Aerodynamic and stable: 30–34mm outer width options reduce the tire–rim shoulder gap on wider tires to improve aero efficiency at speed while maintaining stability in crosswinds.
• Strength and durability: Structural test results include forward compressive strength >300 kg, lateral torsion resistance >50 kg, and spoke hole tension >280 kg with flatness tolerance <0.15mm and roundness <0.3mm.
• Weight grades to suit goals: Available in Standard, Superlight, and Ultralight grades with rim weights tuned for training, endurance, or climbing-focused race builds and a three-year warranty on all grades.
• Customization and OEM-ready: Spoke hole count, hole diameters, and nipple angles are customizable; private label and OEM branding are offered for teams and brands.
• Wheel build compatibility: ERD 538mm supports common spoke and hub selections; compatible with all standard road groupsets at the wheel-build stage via cassette body choice.
• Rider limit and fit: Rated for riders up to 120 kg when built to specification and tested under production tolerances.

Key technical details: ERD 538mm, valve hole 6.5mm (customizable), spoke hole 4.5mm (customizable), assembly hole 7.5mm (customizable), front nipple angle 7° and rear nipple angle 5° or 7°; recommended tire pressure and setup should follow tire manufacturer guidance and intended use.
