Carbon Cyclocross & Gravel Rim 700C | 35mm Height, 30mm Outer / 24mm Inner Width, Tubeless Ready, 330–400g

Carbon 700C Tubeless-Ready Rim — 35mm Height, 30mm Outer / 24mm Inner Width

This V-profile carbon rim is engineered for 700C cyclocross and gravel race bikes. It ships in four validated weight tiers — from a standard 400 g to an extreme-light 330 g — allowing riders to select the stiffness-to-weight balance that matches their discipline. The 24 mm or 25 mm inner width accommodates tubeless tires from 33c to 50c at pressures between 100 psi and 125 psi (max), suiting everything from hardpack CX circuits to loose gravel stages.

Why 35mm Height for Gravel and Cyclocross?

At 35 mm, this rim sits in the crossover zone between an aero advantage and handling stability in crosswinds — shallower than the 40–50 mm rims favoured on road or gravel ultra-distance bikes, yet deeper than 25–28 mm climbing-specific rims. The V-shape profile centres tyre support directly under the contact patch, which reduces rolling resistance on loose or mixed surfaces. Riders who regularly switch between CX mud circuits and gravel events will find the 35 mm depth the most versatile single-rim choice without the crosswind sensitivity of deeper sections.

24 mm vs 25 mm Inner Width — Which Should You Choose?

The 24 mm inner width meets the ETRTO-recommended minimum for 33c–40c tubeless tires and suits most UCI-legal cyclocross setups. Selecting 25 mm inner width provides a slightly wider tyre profile, improves air volume at equivalent pressure, and is better suited to 40c–50c gravel tires. Both options are tubeless-compatible with no rim tape required beyond the standard tubeless strip.

Compatibility Notes

• Fits standard 700C / 622 mm hubs with 100 mm front and 130/135/142 mm rear spacing
• Compatible with both centre-lock and 6-bolt disc brake systems (rim brake version not applicable — this is a disc-brake-only rim)
• Works with standard 6.5 mm tubeless valves
• Maximum rider + kit weight: 120 kg

Frequently Asked Questions

Q: What is a good rim weight for ultralight carbon cyclocross wheels under 400 grams?

A: This rim is available at 370 g (Superlight), 350 g (Ultralight), and 330 g (Extreme Light) — all under the 400 g threshold often cited as the benchmark for competitive CX wheel builds. The Ultralight (350 g) tier is the most popular balance of durability and low rotational mass.

Q: Are 35mm carbon rims better for gravel racing than 40mm or 50mm?

A: For mixed-surface and off-road gravel, 35 mm rims offer lower crosswind sensitivity and a more compliant ride feel than 40–50 mm deep-section rims. They sacrifice a small aerodynamic advantage on long flat gravel stages but recover that time in technical or windy sections.

Q: Can I run this rim tubeless without tape?

A: The rim is tubeless-ready, meaning the hook-bead channel is shaped to seat tubeless tires without additional rim tape in most cases. A standard tubeless strip over spoke holes is still recommended for airtight reliability.

Q: What tire sizes are compatible with a 24mm or 25mm inner-width carbon rim?

A: The 24 mm inner width is optimal for 33c–42c tires; the 25 mm inner width is recommended for 38c–50c tires. Both fall within the 2× internal-width rule of thumb for maximum tyre-to-rim width ratio.

Q: What warranty does this rim carry?

A: The manufacturer offers a three-year warranty covering manufacturing defects under normal riding conditions.
