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

Discover the 29er Superlight Carbon MTB Rim for Peak Performance

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.

Lightweight Design Enhancing Speed and Agility

The 29er superlight carbon MTB rim stands out with its incredibly low weight of just 295 grams. This featherlight rim minimizes rotational mass, making acceleration faster and handling more responsive on technical trails. Crafted from high-quality carbon material, it balances toughness with lightness, allowing riders to enjoy swift climbs and nimble descents without compromise. The lightweight nature reduces rider fatigue, enabling longer rides with improved energy efficiency, making it an indispensable upgrade for serious mountain bikers.

Optimized 23mm Inner Width for Optimal Tire Support

With a 23mm inner width, this MTB rim provides an ideal platform for wider tires commonly used in cyclocross and all-mountain biking. The width offers enhanced tire stability, reducing the risk of pinch flats and improving cornering grip. This helps riders confidently take on varying terrains and technical maneuvers, maintaining control and traction even at high speeds. The rim geometry perfectly complements tubeless tire setups for better performance and fewer flats on rugged trails.

Durability Tailored for Cyclocross and All-Mountain Challenges

Designed for demanding cyclocross and all-mountain rides, this carbon rim delivers excellent strength without added weight. Advanced manufacturing techniques ensure the rim withstands impacts and rough terrain while maintaining its shape and integrity. Its robust construction makes it resistant to cracking and deformation, providing long-lasting reliability. This strength combined with superlight weight means riders don’t need to sacrifice durability for performance, making it a trusted choice for competitive and recreational mountain bikers alike.
