BOLA 700c Carbon Rear Disc Wheel | 28mm Wide, Center Lock

Race-day focus meets confidence on every course with this 700c carbon rear disc wheel built for triathlon and time trial riders. Its 28mm external rim profile and Center Lock disc interface deliver aerodynamic stability and reliable braking, while tubeless or tubular options let you tailor rolling resistance and weight to the demands of your event. ISO 4210 certification and a 12×142mm thru-axle fit mean this wheel integrates with most modern race frames.

700c Carbon Rear Disc Wheel - Designed for triathlon and time trial racing

Choose the tubeless clincher for easier roadside repairs, improved puncture protection, and the ability to run lower pressures with reduced rolling resistance, or select the tubular version for a lighter race-day package aimed at marginal gains. The UD matt carbon construction balances stiffness and impact durability to keep power delivery direct and predictable through high-load efforts.

The wheel's 28mm external and 21mm internal rim widths are optimized for 25–38mm tires, improving tire support and aerodynamics while enhancing crosswind stability compared with narrower rims. A 36-tooth hub engagement design provides secure drivetrain response and effective power transfer under hard accelerations.

Why it fits your routine

• Aerodynamic stability: 28mm external rim profile reduces drag and smooths airflow around modern wide tires for time trial and triathlon speeds.
• Tire system flexibility: Available as tubeless clincher (approx. 1,150 ±30g) or tubular (approx. 1,060 ±30g), letting riders prioritize puncture resilience or minimal weight.
• Disc brake compatibility: Center Lock interface with 12×142mm thru-axle fits most contemporary triathlon and road frames for consistent braking performance on technical courses.
• Durable carbon layup: Unidirectional or marble carbon fiber construction offers a balance of stiffness for sprinting efforts and impact tolerance for race conditions.
• Pro-level certification: ISO 4210 compliance ensures the wheel meets recognized safety and performance standards for road racing applications.
• Responsive hub design: 36T deeper teeth deliver solid engagement and dependable power transfer during surges and time trial intervals.
• Weight profile: Engineered to sit within race-oriented ranges—tubeless and tubular options accommodate athlete preferences and course strategies.
• Warranty: Two-year limited warranty provides manufacturer-backed coverage for typical race and training use.

Technical specifications include a 28mm external / 21mm internal rim width optimized for 25–28mm tires, compatibility with tubeless clincher or tubular tire systems, 12×142mm thru-axle rear axle, Center Lock disc brake interface, UD matt carbon construction, and a hub with 36T engagement. The wheel is ISO 4210 certified and covered by a two-year warranty, making it a purpose-built choice for riders seeking aerodynamic efficiency and modern drivetrain and brake compatibility for competitive events.
