BOLA 88mm Hooked Tubeless Aero Carbon Rim 700C — 27mm Outer / 20mm Inner, ETRTO Certified for TT & Triathlon

When every second matters and aerodynamics decide outcomes, the BOLA 88mm Hooked Tubeless Aero Carbon Rim is built to deliver measurable speed and confidence on the clock. Designed for time trialists and triathletes who want a deep, stable aero rim without premium brand markup, this rim balances a full 88mm U-shaped profile with practical tire compatibility and tested load limits.

BOLA 88mm Hooked Tubeless Aero Carbon Rim 700C - Designed for time trial and triathlon racing

The deep 88mm U-shaped profile is focused on reducing drag at race pace while a 27mm external width and 20mm internal width accommodate modern 25–32mm tires for a smoother aerodynamic footprint and predictable handling. Hooked tubeless bead and ETRTO certification make setup straightforward for riders choosing tubeless or standard clincher systems, and the rim's tested 100–125 psi pressure range supports the higher pressures often used in TT setups.

Riding on an 88mm rim changes how a bike feels at speed: riders experience reduced aerodynamic penalty when holding an aero position and gain the reassurance of a rim engineered to accepted safety standards. For athletes and builders, the combination of a cost-effective factory price position and industry-standard certifications offers practical value without compromising essential performance characteristics.
