The 700C 38mm hookless carbon disc rim internal width is 21mm, outer width is 25mm. Its asymmetric is 2.6mm. And this 38mm deep carbon hookless and tubeless ready road rims provides improved tire profile. As well as performance for wider, more aggressive CX and gravel tires. While also provide 38mm aerodynamic profile for increased speed time to improve efficiency. In addition, the 2.6mm asymmetric profile has created a stiffer, strength and more reliable disc wheel.

Moreover, the hookless design is easy to make with the carbon fiber. The most important is it is easy to install tires. This has solved the biggest problem of the amateurs riders. However, it is better to use a hookless rim at a lower tire pressure. The recommend tire pressure of the rim is 80psi. Furthermore, the mid-depth 38mm carbon rim profile has a reassuring rigidity. And it has built a confidence through rutting and railing corners. It is suitable for long-distance riding, especially for cyclocross and all-day gravel riding.

The feature of 700C 38mm Hookless Carbon Rims Asymmetric 2.6mm：

• The 38mm deep 25mm width carbon hookless rim is lightweight. The material is premium Toray T700 & T800 full carbon fiber.
• The wider and hookless carbon rims are suitable for off-road applications, especially for gravel bikes. Because wider tires increase support and reduce air pressure. Then it has improved overall traction and comfort.
• This rim is tubeless ready rim base profile. Kicking up to the shoulder of the tubeless step. And it has helped to create an excellent rim well seal for first installation and easy sealing of tubeless tires. Once seated, the hookless profile can also lock the beads in place more firmly. This is especially important when running off-road at lower pressures.
• The hookless rim has made with a simpler but superior manufacturing process. Which can achieve better carbon compaction, better resin distribution in the rim. As well as tighter bead seat tolerances, less waste and less scrap.

Why choose our 38mm carbon hookless road disc rim？

The hookless design is not very common on the road. Mainly because the tubeless tire standards are not uniform at all. So it is a risk for the tire to fall off the rim-especially at higher pressures.
Our hookless design offers the best airflow transition from the tire to the rim sidewall. Reducing aerodynamic losses compared to standard hook beads. The design and construction maximize aerodynamic performance and durability. The significant reduction in front and rear resistance ensures that these wheels are extremely fast. But remain stable when the wind changes.

The 38mm carbon gravel disc hookless rim is stiffness and strength. This carbon rim internal width is 21mm. These ultra-wide rims optimized for wide tires. You can drive confidently on severely rugged roads at high speeds.

This strong and super lightweight hookless rim with unidirectional Toray T700 & T800 carbon fiber. Besides the 3K braid to strengthen the spoke holes. The wide aerodynamic profile provides excellent handling and speed.The evolution of the disc-specific structure allows a substantial reduction in weight compared to equivalent rim brake rims. Removing the braking force on the rim can design a sturdy. But very light rim that can focus on the main role of supporting the tire and spoke force.

The features of the 38mm carbon gravell disc hookless rims:

• The carbon hookless rim is 38mm depth with 25mm width. And the material is Toray T700 & T800 full carbon fiber.
• This rim use hookless technology. The hookless rims have manufactured without bead hooks. And the inwardly protruding edges at the top of the rim bed help keep the clincher under pressure. Besides, the inner rim wall of the hookless is flat and straight.
• This hookless carbon rim has stronger rim construction. Moreover it is light weight carbon rims. The aerodynamic profile of the overall system (rim and tire combination) is slightly more.
• The hookless rim have lower manufacturing costs which can benefit the rider if they have passed on. In addition, have less waste generated in the production process.
• The rim is 2-3 years warranty from the data of the original purchase. All of our carbon rims have 100% checked and inspection before shipping. Then have recorded in the data base. Every carbon fiber rims have its series number, to make sure we can check for the after-sale service.

Who is the hookless rim for ?

The carbon Hookless rims have been widely accepted in the mountain area. And have also been applied to gravel bicycles. With the legalization of disc brakes in road races, the rims and the tires are more and more wider. So the hookless brakes have become a real choice for the road market.

If you want wider tires, lower pressure, or ride on rough roads, then the hookless version will be a good choice for you. You will benefit from a more comfortable ride experience due to greater volume. Besides it will enhance impact protection. Gravel riders and off-road riders are often in this situation.
