BOLA 55mm Offset Carbon Road Rim 700C — 30mm Wide, Tubeless, UCI Certified

When the road narrows and every watt and aero advantage matters, the BOLA 55mm offset carbon rim delivers measurable gains for competitive riders and endurance racers. Built for high-speed road events and purposeful training days, this tubeless-ready 700C rim combines aero engineering with practical versatility for varied terrain and race conditions.

BOLA 55mm Offset Carbon Road Rim — Designed for competitive road and endurance riding

Ride with confidence: a 55mm V-shaped aerodynamic profile and 30mm external width smooth airflow around the tire-rim junction, while an asymmetric 2.8mm offset balances spoke tension and improves lateral stiffness. The result is a stable, predictable feel at high speed and improved handling when you push the pace or corner aggressively.

The tubeless-ready 30mm outer / 24mm inner width supports 25–32mm tyre choices, enabling lower pressures for greater comfort and grip without sacrificing rolling efficiency. That combination reduces vibration and rider fatigue over long days in the saddle while retaining responsive power transfer for sprints and climbs.

Why it fits your routine

• Aerodynamic advantage: 55mm rim depth with V-shaped profile reduces drag for high-speed efforts and time trial conditions.
• Asymmetric offset: 2.8mm offset improves spoke tension balance and wheel durability under load.
• Tubeless-ready versatility: Optimized for 25–32mm tubeless road tyres to enhance grip, puncture resistance, and ride comfort.
• Pro-level compliance: UCI certified for international competition; suitable for professional and elite racing environments.
• Weight options: Available in tiers from approximately 440–515g per rim (±15g) so riders can prioritise climbing efficiency or added durability.
• Compatibility and limits: Fits standard 700C frames and Presta valves; recommended tyre pressure range 100–125 psi and maximum rider weight 125kg.
• Custom build support: Valve and spoke drilling options allow hub- and tyre-system-specific configurations for bespoke wheel builds.

Engineered from unidirectional carbon fibre, the rim balances stiffness for efficient power transfer with the compliance needed for real-world road surfaces. The wider profile supports modern tyre volumes that improve rolling resistance and stability in crosswinds compared with narrow rims, giving riders confidence when accelerating, descending, or holding a paceline.

Technical specifications include a 700C rim diameter, 55mm rim height (V-shape aero) with a 30mm outer and 24mm inner width, asymmetric 2.8mm offset, and a verified UCI certification for 2023–2024 event use. Weight varies by production tier (approximately 440–515g per rim with ±15g tolerance). The rim accepts 25–32mm tubeless tyres, uses Presta valve fitment, supports tyre pressures of 100–125 psi, and is rated for riders up to 125kg. Custom valve and spoke drilling options are available to match specific wheel builds and hub standards.
