Full Carbon Tubular Road Bike Rims 25/28/30mm Wide – EN Certified, 120psi, 125kg Rated

Full Carbon Tubular Road Bike Rims — 25 / 28 / 30mm Internal Width

Bola Sporting Goods carbon tubular rims are engineered for road, gravel, and cyclocross (CX) cyclists who demand a measurable performance-to-weight advantage. Available in three internal widths — 25mm, 28mm, and 30mm — these rims are constructed from full unidirectional carbon fibre and meet EN standard certification, supporting up to 120 psi maximum tire pressure and a maximum rider weight of 125 kg. Backed by a 3-year manufacturer warranty and over a decade of OEM production experience.

Technical Specifications

Choosing the Right Rim Width

• 25mm — Optimized for narrow road tires (23–25mm), low rolling resistance on smooth tarmac, and maximum aerodynamic efficiency in competitive road racing.
• 28mm — A versatile crossover width suited to endurance road riding and light gravel use with 28–32mm tires, balancing aerodynamics and comfort.
• 30mm — Designed for gravel and cyclocross applications using 32–40mm tires, prioritizing cornering stability and compliance on mixed terrain.

Why Carbon Tubular for Performance Road Riding?

Carbon rims offer a lower rotational mass and a stiffer rim bed compared to aluminium clincher counterparts, translating to faster acceleration and more precise handling in race conditions. Trade-off to consider: Tubular tires require gluing or tape bonding and are less convenient to change roadside compared to clincher or tubeless-ready systems. They are most appropriate for competitive race day use, time trials, and criteriums where weight savings and stiffness are prioritised over convenience.

Frequently Asked Questions

Q: Are these rims compatible with disc brake or rim brake systems?

A: Please contact Bola Sporting Goods directly to confirm brake compatibility for a specific rim profile, as configurations vary by model.

Q: Can a 125 kg rider safely use these carbon tubular rims for road racing?

A: Yes. These rims are rated to a maximum rider weight of 125 kg under normal road cycling conditions. Riders near the weight limit should ensure tire pressure does not exceed 120 psi and inspect rims regularly for stress indicators.

Q: What is the difference between 25mm and 30mm wide carbon rims for road cycling?

A: A 25mm rim pairs with narrower tires for lower aerodynamic drag on smooth roads; a 30mm rim accommodates wider tires for improved grip, comfort, and stability on gravel or rough tarmac. Width selection should match your primary tire size and terrain.

Q: Do these rims support tubeless tires?

A: These are tubular-specific rims. They are not configured for tubeless or clincher tire systems. For tubeless options, contact Bola Sporting Goods to discuss available rim profiles.

Q: What certifications do these rims carry?

A: These rims are manufactured to EN standard certification. Contact us for full test documentation if required for team or regulatory compliance.
