Bola 700c 45mm Asymmetric Carbon Tubeless Rim, 28mm Outer, T700/T800 UD, Disc & Rim Brake Compatible

Take a technical edge on endurance rides, club events, and gravel adventures with a rim built for balanced stiffness, low weight, and aerodynamic stability. The Bola 700c 45mm asymmetric carbon tubeless rim is designed to deliver predictable handling whether you’re pushing tempo on paved roads or linking fast gravel tracks.

Bola 700c 45mm Asymmetric Carbon Tubeless Rim - Designed for road and gravel riders

Made from premium T700/T800 unidirectional carbon fiber, this 45mm U-shaped rim blends aerodynamic depth with a wide 28mm outer profile to support modern, higher-volume tires. The asymmetric internal profile re-centers spoke tension for improved lateral stiffness and wheel durability, a real benefit when using disc brakes or carrying higher loads on endurance rides and custom wheel builds.

The rim’s tubeless-ready construction follows ISO 622 / ETRTO standards and supports both hooked and hookless beads, giving you flexibility for tubeless setups or traditional inner tube use. Available in multiple weight options—Extreme-Light (375g), Ultra-Light (380g), Super-Light (405g), and Standard (460g)—it fits a range of priorities from racing-focused lightness to durability-focused builds.

Why it fits your routine

• Balanced performance: 45mm depth for aerodynamic gains without the extreme crosswind sensitivity of deeper profiles.
• Modern tire support: 28mm outer width and recommended tubeless tire range of 25–32mm improve comfort and rolling efficiency on mixed surfaces.
• Asymmetric design: Equalized left/right spoke tension enhances lateral stiffness and long-term wheel durability, especially beneficial for disc brake setups.
• Material quality: Constructed from T700/T800 UD carbon fiber to combine strength and weight savings for endurance and competitive use.
• Compatibility: Supports disc and rim brake hubs, Center Lock or 6-bolt disc interfaces, and fits standard spoke types through 4.5mm spoke holes for common J-bend and straight-pull spokes.
• Bead and tubeless readiness: ETRTO/ISO 622-compliant tubeless-ready rim available in hooked or hookless bead options to match your tire and tire insert choices.
• Weight choice: Four weight variants let builders prioritize lowest possible rotating mass or enhanced impact resistance depending on intended use.
• Quality assurance: Dynamic balance tested to under 3g, flatness tolerance below 0.15mm, and roundness under 0.3mm for reliable wheel building and ride quality.
• Certifications and warranty: ISO 622 and ETRTO compatibility with a 3-year warranty covering manufacturing defects.
• Rider limits and fit: Recommended for riders up to 100kg and optimized for 700c (ISO 622) wheel systems.

Compared to many mid-tier and premium models, the Bola rim offers a competitive combination of Toray-grade carbon material, modern rim width, and asymmetric engineering while avoiding premium brand markup by supplying factory-direct quality and a standard three-year warranty.

Recommended uses include lightweight road wheel upgrades, endurance and long-distance riding where comfort and tire volume matter, custom race and gravel wheel builds, and OEM or workshop projects requiring ISO-certified carbon rims that accept both tubeless and tube setups.

Technical specifications include 700c (ISO 622) diameter, 45mm asymmetric U-shape depth, 28mm outer width with 21mm or 23mm inner options, 4.5mm spoke holes, tubeless-ready bead compatible with hooked or hookless configurations, recommended tire range 25–32mm, multiple weight variants from 375g to 460g, and a manufacturer-backed 3-year warranty covering material and workmanship defects.
