Full Carbon Tubular Road & Gravel Bike Rim – 25/28/30mm Width, 700C, EN Certified

Full Carbon Tubular Rim for Road, Gravel & CX Bikes – 25/28/30mm Inner Width

A high-performance, full carbon fiber tubular rim engineered for road, gravel, and cyclocross bicycles. Available in 25mm, 28mm, and 30mm outer widths, it supports tire pressures up to 120psi and riders up to 125kg — making it a reliable choice for competitive racing and endurance cycling. Certified to EN standards and backed by a 1-year manufacturer warranty.

Key Specifications

Which Width Should You Choose?

• 25mm outer width: Optimized for road racing. Reduces aerodynamic drag at speed and pairs well with 23–25mm tubular tires for low rolling resistance on smooth tarmac.
• 28mm outer width: A balanced all-rounder suited to endurance road riding and light gravel. Accommodates 25–28mm tires for improved comfort on mixed surfaces.
• 30mm outer width: Best suited for gravel and cyclocross riding. Provides a wider tire bed for 28–32mm tubulars, improving traction and stability on loose terrain.

Performance & Design Notes

Full carbon fibre construction delivers a high stiffness-to-weight ratio, reducing rotational mass compared to alloy equivalents. The tubular design bonds the tire directly to the rim bed, eliminating the bead seat used in clincher rims — a setup preferred by competitive road and CX racers for its flat-resistance properties and superior ride feel at race pressures.

Known tradeoff: Tubular rims require a dedicated tubular tire and specialized gluing or tape installation. They are not compatible with clincher or tubeless tires. Riders transitioning from clincher setups should factor in tire cost and installation time.

Frequently Asked Questions

What are the best full carbon tubular rims for road and gravel bikes?

This rim is purpose-built for road, gravel, and cyclocross applications. The 25mm width suits road racing; the 30mm width is better suited to gravel performance. All widths use full carbon fibre construction and are EN-certified.

Can a carbon tubular rim safely handle 120psi for long rides?

Yes. This rim is rated to a maximum tire pressure of 120psi (8.3 bar), which covers the full operating range of standard road tubular tires. Do not exceed the rated pressure as specified by the tire manufacturer.

What is the difference between tubular and clincher carbon rims for racing?

Tubular rims bond the tire directly to the rim using glue or tape, removing the mechanical bead seat. This results in a lighter overall wheelset, a smoother ride at high pressures, and improved flat-ride-out safety. Clincher rims are easier to service but are generally heavier and require an inner tube or tubeless setup.

Is a 25mm or 30mm wide carbon rim better for gravel cycling?

For gravel, the 30mm outer width provides a wider tire contact patch, supporting larger volume tires that improve traction and vibration damping on loose or uneven terrain. For pure road or mixed-surface endurance riding, the 28mm is a strong compromise.

Are these rims available for OEM or private label orders?

Yes. OEM and custom branding options are available including surface finish, decal design, spoke hole count, and rim depth. Contact us directly for minimum order quantities and production timelines.
