Bola 700c Carbon Tubeless Road Rim — 35mm Deep, 28mm Outer / 21mm Inner (Hooked)

Race-ready depth with practical everyday performance: this 35mm-deep 700c carbon rim balances aerodynamic benefit and ride compliance for road training, racing, and mixed-surface riding. Tubeless-ready from the factory and offered in multiple weight grades, it lets you tune a wheelset for durability, all-round racing, climbing, or weight-optimized race builds.

Bola 700c Carbon Tubeless Road Rim - Designed for road racing and performance training

The U-shaped 35mm profile with a 28mm outer width creates a continuous aero profile with wider tires while the 21mm inner width (hooked) or 23mm inner width (hookless) lets you choose air volume and pressure characteristics that suit your tires and riding style. The rim is tubeless-ready out of the factory, compatible with standard road hub spacing, and available with customizable valve, spoke, and assembly hole diameters for tailored wheel builds.

Ride comfort improves with increased air volume when using the hookless 23mm option and appropriate tires, while the hooked 21mm variant preserves broad compatibility with clincher and tubeless tires that are not hookless-certified. Structural tolerances and balance specs help ensure consistent handling and reliable performance across training and competition conditions.

Why it fits your routine

• Versatile depths and aerodynamics: 35mm rim depth and 28mm outer width reduce the aerodynamic "light bulb" effect with 28–32c tires for faster rolling at speed.
• Choice of inner bead design: Hooked 21mm inner width maintains broad tire compatibility; hookless 23mm inner width increases air volume and ride compliance when used with ETRTO-approved hookless tires.
• Tubeless-ready out of the box: No conversion tape required on the rim bed, simplifying setup for tubeless tires and sealant use.
• Multiple weight grades: Select Standard (415 ±15 g), Super Light (370 ±10 g), Ultra Light (350 ±10 g), or Extreme Light (330 ±10 g) per rim to prioritize durability, all-round racing, climbing, or weight-optimized race builds.
• Clear structural performance: Forward compressive strength >300 kg, lateral torsion resistance >50 kg, and spoke hole tension rating >280 kg support reliable wheel builds.
• Precision fit and finish: Dynamic equilibrium <3 g, flatness tolerance <0.15 mm, and roundness tolerance <0.3 mm for consistent balance and trueness.
• Pressure and load limits: Min/max tire pressures listed at 100/125 psi for rated configurations and maximum rider weight of 120 kg (264 lb).
• Hub and rotor compatibility: Works with standard road hubs (100mm front / 130mm or 142mm rear) and supports center-lock or 6-bolt disc configurations when specified at build.
• Customizable build options: Valve hole, spoke hole, assembly hole diameters, and nipple angles can be customized on request to match specific hub and spoke choices.

Hooked rims (21mm inner) are recommended when you need full compatibility with clincher and non-hookless tubeless tires or higher-pressure setups, while hookless rims (23mm inner) are intended for lower-pressure, higher-volume setups with ETRTO-approved tires and optimized aero interaction. ERD measures 568mm and the default valve hole diameter is 6.5mm, with spoke hole diameter 4.5mm and assembly hole diameter 7.5mm available as standard sizes or customizable on request.
