Bola 700c Carbon Tubeless Road Rim – 60mm Deep, 28mm Wide

Bola 700c Carbon Tubeless Road Rim — 60mm Deep, 28mm Wide

High-performance 700c carbon rim engineered for road racing, endurance and lightweight builds. The U-shaped 60mm deep profile with a 28mm outer width balances aerodynamic efficiency with stability across crosswinds while offering increased tire volume for improved compliance and rolling resistance.

Key Specifications

• Wheel size: 700c
• Rim profile: U-shape, depth 60mm
• Outer width: 28mm; inner width: 21mm (hooked) or 23mm (hookless)
• ERD: 518mm
• Valve hole: 6.5mm (customizable); spoke hole: 4.5mm (customizable)
• Assembly hole: 7.5mm (customizable); nipple angles: 7° front / 5°–7° rear (customizable)
• Recommended tire pressures: 100–125 psi max; max rider weight: 120 kg (264 lb)

Weight Grades

• Standard: 535 ±15 g — training and durability-focused builds
• Super Light: 485 ±10 g — all-round racing
• Ultra Light: 455 ±10 g — climbing and lightweight builds
• Extreme Light: 435 ±10 g — weight-optimized race builds

Performance & Tolerances

• Forward compressive strength: >300 kg; lateral torsion resistance: >50 kg
• Spoke hole tension rating: >280 kg; dynamic equilibrium <3 g
• Flatness tolerance <0.15 mm; roundness tolerance <0.3 mm

Hooked vs Hookless

Hooked (21mm inner) is compatible with standard clincher and tubeless tires and suits mixed-surface use or higher-pressure needs. Hookless (23mm inner) increases air volume and ride compliance and is recommended with ETRTO-approved hookless-compatible tires at lower pressures (typically 72–87 psi).

Compatibility & Build Notes

Rims are tubeless-ready from the factory and work with standard road hubs (100mm front / 130mm or 142mm rear). Supports center-lock or 6-bolt disc options and accepts custom hole diameters on request.
