# 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.
