Bola 700c Carbon Tubeless Road Rim — 50mm Depth, 28mm Width, Hooked or Hookless

When you push for speed on a rolling race course or settle into a long gran fondo, the Bola 700c Carbon Tubeless Road Rim delivers an aerodynamic 50 mm profile and modern tubeless fitment that help you ride faster and ride longer. Choose a hooked 21 mm inner width for broad clincher and tubeless compatibility or a 23 mm hookless inner width to pair with wider tires at lower pressures for added compliance.

Bola 700c Carbon Tubeless Road Rim - Designed for road racing, gran fondos, and endurance rides

The 50 mm U-shaped carbon rim and 28 mm outer width are engineered to integrate with contemporary tire profiles, improving aerodynamic performance while supporting tire volumes that enhance ride comfort on long days. Tubeless-ready construction means no conversion tape is required, simplifying a modern road setup whether you prioritize speed, comfort, or durability.

Why it fits your routine

• Aerodynamic advantage: 50 mm depth and 28 mm outer width optimize tire integration for road racing and sustained-speed efforts.
• Tire and pressure flexibility: Hooked (21 mm inner) supports 25c–32c tires up to 125 psi; hookless (23 mm inner) pairs with 28c–35c ETRTO-approved hookless tires at recommended 72–87 psi for lower-pressure comfort.
• Selectable weight grades: Four layups from 370 g to 470 g per rim let you prioritize lightweight climbing performance or extra durability for training and rough roads.
• Reliable tubeless fit: Tubeless-ready rim bed built to ETRTO 2023 standards so you can run modern tubeless road tires without conversion tape.
• Build-friendly dimensions: 540 mm ERD, 6.5 mm valve hole, 4.5 mm spoke hole, and 7.5 mm assembly hole with customization options for valve, spoke, assembly-hole, and nipple-angle specs.
• Durability and safety margins: Structural test results include forward compressive strength >300 kg, lateral torsion resistance >50 kg, spoke-hole tension rating >280 kg, and measured tolerances for dynamic equilibrium (<3 g), flatness (<0.15 mm), and roundness (<0.3 mm).
• Weight-bearing capacity: Rated for riders up to 120 kg (264 lb), accommodating heavier riders and loaded setups within stated limits.
• Warranty: Three-year manufacturer's warranty covering structural defects under normal riding conditions, excluding crash damage and use outside weight or pressure limits.

Recommended use cases include road-racing builds seeking aerodynamic gains with 28c–32c tires, gran fondo or endurance wheelsets using the wider hookless inner width for lower-pressure comfort, lightweight climbing builds with the Ultra Light or Extreme Light layups, and training or rough-road wheels using the Standard layup for added impact resistance.
