Bola 700c Carbon Rim 80mm Deep × 34mm Wide UV (Toroidal) — Triathlon & Ironman Racing

On a flat triathlon course the Bola 700c 80mm Deep 34mm Wide Carbon Rim helps you hold speed and composure when every watt and gust matters. Built with a wind-optimized UV (toroidal) profile and Toray carbon construction, this rim is aimed at riders who need aerodynamic stability and race-ready stiffness for long, high-speed efforts such as Ironman and time trials. Its 34 mm outer width and 23 mm internal width pair with modern 25–28 mm tyres to smooth airflow and improve crosswind performance.

Bola 700c 80mm Deep 34mm Wide UV Rim - Designed for triathlon and time-trial performance

The deeper 80 mm section and toroidal shaping reduce drag across a range of yaw angles while a durable UV-cure resin finish preserves layup integrity under repeated race use. With compatibility for tubeless, clincher and tubular systems, this rim adapts to different tyre preferences and pit strategies, and each rim is individually tested for flatness, spoke tension and lateral torsion to ensure consistent quality.

Riders experience a confident, stable feel in variable wind thanks to the wider 34 mm profile and the rim’s aerodynamic tuning; weight remains competitive at 580–610 g per rim while structural testing supports everyday race demands up to a 120 kg rider limit.

Why it fits your routine

• Race-focused aerodynamics: UV (toroidal) profile engineered to reduce drag and manage airflow for sustained speed on flat and rolling courses.
• Modern tyre pairing: 23 mm internal width optimized for 25–28 mm tyres to balance comfort, rolling resistance and sealing performance with tubeless setups.
• Stiffness and power transfer: Toray carbon construction delivers the stiffness required for sprint finishes and steady high-power intervals.
• Durability and validation: Multi-stage QA with flatness <0.15 mm, spoke tension >280 kg and lateral torsion testing, plus a 3-year warranty on structural/material faults.
• Versatile compatibility: Designed for tubeless, clincher and tubular tyres and a customizable 6.5 mm valve hole to suit different wheel builds.
• Practical weight range: 580–610 g per rim (±15 g) strikes a balance between low mass and structural reliability for multi-day events and endurance race use.
• Performance limits: Rated for riders up to 120 kg and tyre pressures in the 100–125 psi range when using recommended tyre sizes.
• Options for tuning: Available in a main 34 mm outer width and a 30 mm variant to match handling preferences or discipline-specific setups.

Designed for triathlon, Ironman and road time trial builds, the Bola 700c 80mm UV rim pairs aerodynamic efficiency with tested structural performance to support riders seeking reliable speed and stability during long, high-intensity efforts.
