Bola 700c Carbon Tubeless Road Rim — 55mm Depth, 28mm Outer Width (Hooked or Hookless)

Roll into long efforts, breakaway sprints, or steep climbs with a rim engineered to balance aero performance, tire volume, and structural strength. The Bola 700c Carbon Tubeless Road Rim pairs a 55mm U-shaped profile with a 28mm outer width to create a stable aero platform for modern road tires.

Choose hooked or hookless bead options and a range of weight grades to match race, training, or lightweight climbing builds.

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

The rim’s wider 28mm outer width and U-shaped 55mm profile deliver an aerodynamic shape that integrates smoothly with 28–32c tires for reduced aerodynamic drag. With tubeless-ready construction straight from the factory and selectable inner widths (21mm hooked or 23mm hookless), the rim supports lower pressures for improved compliance while maintaining compatibility with standard road hub spacing and disc configurations.

Why it fits your routine

• Versatile compatibility: 700c sizing with options for hooked (21mm inner) or hookless (23mm inner) beads to match your tire choice and riding conditions.
• Aerodynamic advantage: 55mm depth and 28mm outer width provide a continuous aero profile with wider road tires to reduce the light-bulb effect when paired with 28–32c tires.
• Tubeless-ready out of the box: No conversion tape required on the rim bed, simplifying setup for modern tubeless road tires.
• Range of weight grades: Select from Standard (515±15 g), Super Light (465±10 g), Ultra Light (445±10 g), or Extreme Light (425±10 g) per rim to prioritize durability or climbing performance.
• Structural performance: Forward compressive strength >300 kg, lateral torsion resistance >50 kg, and spoke hole tension rating >280 kg for durable builds.
• Precision tolerances: Dynamic equilibrium <3 g, flatness tolerance <0.15 mm, and roundness tolerance <0.3 mm to support balanced high-speed performance.
• Pressure & load limits: Recommended tire pressures vary by setup; listed min/max tire pressures are 100/125 psi for appropriate tube/tire combinations, and the rim supports a maximum rider weight of 120 kg (264 lb).
• Customizable details: ERD 528 mm with customizable valve hole (6.5 mm), spoke hole (4.5 mm), and assembly hole (7.5 mm) diameters plus adjustable nipple angles for build optimization.
• Hooked vs. hookless guidance: Hooked 21mm inner width fits a broad range of clincher and tubeless tires and suits mixed-surface or higher-pressure needs; hookless 23mm inner width increases air volume, improves ride compliance, and works with ETRTO-approved hookless-compatible tires at lower recommended pressures (typically 72–87 psi).
• Hub and rotor compatibility: Compatible with standard road hub spacing (100mm front; 130mm or 142mm rear) and supports center-lock or 6-bolt disc configurations when specified at build.

Technical riders and wheel builders will appreciate the clear ERD, spoke and valve hole specs, selectable bead design, and the multiple weight options that let you tune a wheelset for durability, all-round racing, or ultra-light climbing-focused builds.
