29er Carbon MTB Rim 23mm Inner Width | 295g Superlight | Cyclocross & All-Mountain

29er Carbon MTB Rim — 23mm Inner Width, U-Shape Profile

A 23mm inner width, U-shape carbon rim engineered for 29-inch cyclocross and all-mountain (AM) riding. Available in two weight options — Standard (355 ± 10 g) and Superlight (295 ± 10 g) — it delivers a measurable weight advantage over comparable alloy rims (typically 450–550 g) without sacrificing structural integrity. Maximum rider weight: 100 kg. Recommended tire pressure: 45–65 psi.

Core Specifications

Performance by Riding Discipline

• Cyclocross: The low 23 mm rim height reduces wind resistance during technical, high-cadence course sections. The U-shape profile provides predictable tire seating for rapid pressure changes between mud and hardpack surfaces.
• All-Mountain (AM): A 23 mm inner width supports trail tires from 2.2″ to 2.6″, optimizing casing spread for improved cornering contact patch and reduced pinch-flat risk at lower pressures.
• Small & Medium Cycling Brands / OEM: Custom hole diameters, nipple angles, spoke counts, and finish options available. Contact us for MOQ and lead-time details.

Weight Tradeoff: Standard vs. Superlight

The Superlight variant (295 ± 10 g) offers a 60 g reduction per rim — approximately 120 g per wheelset — which is measurable in timed climbs and acceleration. The Standard variant (355 ± 10 g) is the recommended choice for riders prioritizing long-term durability under sustained loads or frequent impacts, without a significant performance penalty.

Warranty & Quality Assurance

Every rim is backed by a 3-year manufacturer warranty. Produced by a carbon fiber rim specialist with over a decade of supply experience to professional cycling teams and brands across Europe and North America.

Frequently Asked Questions

What is the best lightweight carbon 29er MTB rim for cyclocross?

This rim's 23 mm height minimizes aerodynamic drag in variable cyclocross conditions, while the Superlight option at 295 g delivers one of the lowest weight-per-strength ratios in this rim class. The U-shape profile ensures consistent tubeless or clincher tire seating across surface transitions.

Is a sub-300 g carbon 29er rim worth it?

At 295 ± 10 g (Superlight), the weight saving versus the Standard (355 ± 10 g) is 60 g per rim. For competitive XC or cyclocross riders where rotational weight directly affects acceleration, this is a meaningful gain. For AM riders prioritizing impact resilience, the Standard variant offers the better durability-to-weight balance.

What inner rim width is best for 29er trail or all-mountain riding?

A 23 mm inner width is compatible with 2.2″–2.6″ tires, the most common range for trail and AM riding. This width optimizes tire casing spread, improving cornering traction and lowering the effective minimum pressure before pinch-flat risk increases.

Carbon vs. alloy 29er rims for cyclocross — which is better for the price?

Carbon rims in this category typically weigh 295–380 g versus 450–550 g for quality alloy equivalents. The weight and stiffness advantages favor carbon for competitive use. This rim is manufactured at scale with direct OEM pricing, closing the traditional carbon-to-alloy cost gap for brands and team buyers.

What specs should I look for in a 29er carbon rim for all-mountain riding?

Key specs for AM use: inner width ≥ 23 mm for tire support, spoke hole tension tolerance > 250 kg for build durability, dynamic equilibrium < 3 g for smooth high-speed rolling, and flatness tolerance < 0.2 mm for consistent brake track performance. This rim meets or exceeds all four thresholds.
