29er Hookless Carbon Tubeless MTB Rim – 20mm Profile, 29mm Inner Width, Offset, 325–370g (XC/AM)

Discover the Performance of the 29er Hookless Carbon MTB Rim

A hookless, tubeless-ready 29er carbon rim weighing 325–370g per piece, built for cross-country (XC) and all-mountain (AM) riding. The 29mm inner width accommodates 2.3–2.6" tires at recommended pressures of 45–65 psi, and the asymmetric (offset) spoke bed improves tension balance on the drive side by evening spoke angles across the wheel.

Key Specifications

Structural Strength Testing Results

• Forward Compressive Strength: >300kg
• Lateral Torsion Resistance: >50kg
• Spoke Hole Tension: >280kg
• Dynamic Equilibrium (imbalance): <3g
• Flatness Tolerance: <0.15mm
• Roundness Tolerance: <0.3mm

Ride Discipline Fit

• Cross-Country (XC): The superlight 325g option and low 20mm profile minimize rotational weight, reducing energy cost on climbs. Pairs well with 2.2–2.4" XC tires at 50–65 psi.
• All-Mountain (AM): The 29mm inner width supports high-volume 2.4–2.6" casings for better cornering stability and compliance on technical terrain. Recommended tire pressure: 45–52 psi.

Hookless vs. Hooked Rim — Key Tradeoffs

Note: Hookless rims require tubeless-compatible tires. Always verify tire manufacturer's hookless approval before mounting. Maximum tire pressure is 65 psi; exceeding this risks bead failure.

Offset (Asymmetric) Rim Design

The spoke holes are laterally offset (Left 5° / Right 7°) rather than centered on the rim centerline. On a rear wheel, this reduces the tension differential between the drive-side and non-drive-side spokes, producing a more evenly tensioned, laterally stiffer wheel. This is particularly beneficial on 12-speed drivetrains where the cassette forces a steeper drive-side spoke angle.

Frequently Asked Questions

Q: Is a 29mm inner width carbon rim suitable for all-mountain riding with 2.4" tires?

A: Yes. A 29mm inner width is well within the recommended range for 2.4" MTB tires (ETRTO recommends an inner width 25–35% of the tire's nominal width). The wider bed improves tire casing support and cornering stability compared to a 25mm rim.

Q: What tire pressure should I run on a hookless rim?

A: This rim is rated for 45–65 psi. Most AM/XC tubeless setups run 38–55 psi depending on rider weight and terrain. Do not exceed 65 psi on this hookless rim.

Q: Can I use a tube with this hookless rim in an emergency?

A: Hookless rims are not designed for inner tubes. In a field emergency, some riders briefly use a tube at very low pressure to reach safety, but this is not manufacturer-approved and carries a risk of bead unseating.

Q: How does the offset spoke pattern help on a 29er rear wheel?

A: The asymmetric hole position shifts the rim's spoke flange reference point, reducing the tension imbalance between drive and non-drive sides. This results in fewer broken spokes and improved lateral rigidity under load.

Q: What is the difference between the standard (370g) and superlight (325g) versions?

A: The superlight variant uses a refined carbon layup with tighter tolerances (±10g vs. ±15g), reducing weight by approximately 45g per rim (90g per wheelset). For weight-focused XC racing, the superlight option is recommended; for heavier AM use, the standard version offers a more conservative safety margin.

Lightweight Design and Tubeless Compatibility

The 29er hookless carbon MTB rim offers an ultra-lightweight solution for serious riders, weighing between 325 and 370 grams depending on size. Its tubeless-ready design allows for easy setup with modern tubeless tires, reducing weight and improving traction on rough trails. The hookless rim profile eliminates the traditional hook bead, resulting in a smoother tire mounting experience and better compliance with tubeless tire standards. This rim's cutting-edge carbon fiber construction ensures durability while shaving off unnecessary weight, making it ideal for cross-country (XC) and all-mountain (AM) riders seeking performance gains.

Optimal Width and Offset for Stability and Control

Featuring a 29mm inner width and a 20mm profile, this rim provides an optimal balance of stiffness and flexibility needed for modern mountain biking demands. The offset design improves tire alignment, enhancing cornering stability and traction, especially on technical sections. The wider rim inner width supports a broader tire footprint, allowing riders to run lower tire pressures without compromising rim protection. This boost in stability translates to greater confidence on challenging terrain, making it a perfect upgrade for XC racers and AM enthusiasts aiming to enhance their bike's handling and reliability.

Durability and Versatility Tailored for XC and AM Riding

Crafted from high-quality carbon fiber materials, the 29er hookless carbon MTB rim strikes a perfect balance between lightweight performance and robust durability. Its design accommodates a broad range of tubeless tires and withstands the rigors of aggressive trail riding. Whether tackling rocky descents or navigating technical climbs, this rim delivers consistent performance with reduced risk of damage. The weight range between 325 to 370 grams also means riders can tailor the choice based on their riding style and terrain, making it versatile enough for cross-country races or all-mountain adventures.
