34mm external width carbon rims for all-road and gravel

Bola's 700C 34mm external width rims pair a 25–28mm internal width with profiles tuned for high-volume all-road and gravel tires. The wider bed supports 30c–45c tires with a smooth aerodynamic transition from tire sidewall to rim, improving sidewall support and cornering stability on mixed surfaces.
