The BOLA 700C carbon gravel rim offers a 45mm deep, 30mm wide, offset V-shape profile. Weighing 360–435g (depending on layup), it is designed for competitive gravel racing and endurance cycling. The rim supports both hooked (24mm IW) and hookless (25mm IW, ETRTO 2023) tire setups, allowing for versatile tire choices. Maximum rated tire pressure is 125 psi. Recommended for riders up to 120 kg.

Frequently Asked Questions (FAQ)

What are the advantages of a carbon rim for gravel racing?
Carbon rims deliver weight savings (as low as 360g), enhanced lateral stiffness, and increased fatigue resistance per ISO 4210-7 testing, improving acceleration and day-long handling.
Should I choose hooked or hookless for my setup?
For tire pressures above 70 psi or standard clincher tires, choose hooked. For tubeless gravel tires (28–50mm), hookless (ETRTO 2023) offers wider inner width and lower pinch-flat risk.
What tire width is ideal for this rim?
For gravel racing on a 30mm outer/24–25mm inner rim, 35–45mm tires maximize comfort, grip, and fit.
Is a 45mm deep rim stable in crosswinds?
Deeper rims (45mm) improve aerodynamic efficiency on open terrain but may require advanced handling in gusty crosswinds.
