BOLA 120mm Aero Carbon Rim 700C – Hooked Tubeless, 28mm Wide, Time Trial & Triathlon

When every second counts on a flat time trial or triathlon course, the BOLA 120mm Aero Carbon Rim is built to translate power into sustained high speed. Its 120mm deep UV-shaped profile and tubeless-ready hooked bead deliver aerodynamic advantage and reliable tire retention when paired with 700x25c or 700x28c tires. Riders seeking maximum straight-line performance will find this rim balances low drag with structural strength for competitive conditions.

BOLA 120mm Aero Carbon Rim 700C - Designed for time trial & triathlon

Ride with confidence at race pace: the combination of a high-modulus carbon composite layup, a 28mm external width and a 21.5mm internal width provides a modern tire platform that improves tire shape and aerodynamic interaction. The rim’s tubeless-ready, hooked bead supports higher road tire pressures and secure seating to meet the demands of competitive road racing.

Why it fits your routine

• Maximum aero performance: 120mm deep UV-shaped profile reduces aerodynamic drag for flat, straight courses and high-speed efforts.
• Modern tire compatibility: 28mm outer and 21.5mm inner width supports 700x25c and 700x28c tubeless or clincher tires for optimized tire profiles.
• Hooked tubeless bead (ETRTO): Tubeless-ready certification ensures secure tire retention and compatibility with higher pressures.
• Race-ready strength-to-weight: High-modulus carbon fiber construction delivers a claimed weight of 655g ±15g while supporting riders up to 125kg.
• High pressure rating: Designed for tire pressures in the 100–125 psi range typical of race setups on narrow, high-performance tires.
• Certified standards: ETRTO tubeless-ready certification indicates compliance with established safety and compatibility protocols.

Performance trade-offs are clear: the 120mm depth gives the highest aerodynamic advantage on straight, flat courses but can be more affected by crosswinds than shallower sections such as an 88mm rim, so selection should match course profile and handling preferences.
