This bicycle rim is centered on full carbon fiber material, integrating innovative design and practical performance, specially crafted for users pursuing high-quality riding experiences. It features a unique wave rim design, combined with the optimal dimensions of 35mm height and 28mm external width. This not only ensures aerodynamic efficiency but also enhances tire support and grip, making flat-road sprints, cornering, and riding on complex road conditions more stable and effortless.

The rim is equipped with a disc brake system, which delivers strong braking force with precise control. Unaffected by weather conditions, it provides reliable safety guarantees for various riding scenarios. In addition, the rim offers two designs: hookless and hooked. The hookless design is suitable for tubeless tires, featuring convenient installation and maintenance, as well as both shock absorption and puncture resistance. The hooked design is compatible with various tire types, providing stable fixation under high pressure, making it ideal for users who pursue traditional configurations and high-speed performance.

Meanwhile, this rim supports personalized customization - you can choose the original carbon fiber appearance or custom painting as needed, and the number of spoke holes can also be flexibly adjusted to meet the individual needs of different users for appearance and performance.

Product Features and Advantages

High-Quality Carbon Fiber Material:

Crafted from high-quality full carbon fiber, it is lighter than ordinary metal rims. This allows the rim to rotate flexibly, ensuring smooth acceleration and less effort when climbing. Meanwhile, the carbon fiber material is sturdy and durable, resisting deformation and damage even on bumpy gravel roads or with minor collisions. Its unique woven surface texture offers both a high-end visual appeal and a pleasant touch.

Wave Design:

The wave-shaped design is not only distinctive in appearance but also highly practical. The wave structure on the rim can disperse impact force when encountering road bumps, reducing vibrations transmitted to the human body. After long rides, the fatigue in the arms and waist will be alleviated. Moreover, while ensuring rigidity, this design enables direct power transmission during intense riding without a weak feel; the rim remains stable when turning, making it easy to handle.

Optimal Size Combination:

The 35mm height and 28mm external width are reasonably matched. The 35mm height helps reduce air resistance, making the rim more energy-efficient during flat-road rides and maintaining speed well. The 28mm external width provides sufficient support for the tire, which remains plump after inflation and has a larger contact area with the ground. Whether sprinting on asphalt roads, turning on mountain bends, or riding on slippery muddy ground, it can offer strong grip, enhancing riding confidence.

Reliable Disc Brake System:

The disc brake system performs reliably with strong and stable braking force. A light squeeze on the brake lever can achieve effective deceleration, and it can ensure braking performance even on long downhill sections. In addition, the disc brake is not affected by weather conditions; its braking performance remains stable in rainy days or muddy environments, improving riding safety. The rim comes in two designs: the hookless design is suitable for tubeless tires, facilitating installation and maintenance while reducing the risk of punctures; the hooked design has strong compatibility, compatible with ordinary clincher tires, tires with inner tubes, or tubeless tires, and can firmly fix the tire after inflation to prevent deviation.

Enhanced riding efficiency：

It supports personalized customization to meet different needs. You can retain the original texture of carbon fiber for a low-key and stylish look; you can also choose different color coatings or even add personalized patterns to enhance uniqueness. The number of spoke holes can be adjusted according to needs: increasing the number for better rim sturdiness or reducing it for lightweight, fully adapting to personal preferences.

Strict Quality Control:

KOBIKE do 100% tire pressure(150 PSI), flatness(＜0.2mm) and roundness(＜0.2mm) inspections before shipping, also offering 2 years warranty for our carbon rims.

Product Structure

Material Composition:

The entire rim is constructed from high-quality full carbon fiber. This material forms the core structure, leveraging its high strength and low density to achieve the rim's lightweight and durable properties. The carbon fiber is woven into a specific pattern, creating a sturdy framework that underpins the rim's overall performance.

Wave Rim Structure:

The outer surface of the rim features a unique wave design. This undulating structure is integrated into the carbon fiber framework, with each wave segment evenly distributed around the rim. The wave shape is precisely engineered to disperse impact forces, adding both functional and structural characteristics to the rim.

Size-Based Structural Design:

With a 35mm height, the rim's vertical structure is designed to optimize aerodynamics. Its 28mm external width gives the rim a wider profile, providing a stable base for tire mounting. The internal structure corresponding to these dimensions ensures sufficient support for the tire while maintaining the rim's overall rigidity.

Disc Brake Integration Structure：

The rim is designed to accommodate a disc brake system. Specific mounting points and structural reinforcements are incorporated at the appropriate positions on the rim to securely attach the disc brake components. This integration ensures that the braking force is effectively transmitted and distributed, without compromising the rim's structural integrity.

Hookless and Hooked Structural Variations：

 For the hookless design, the inner edge of the rim is a straight sidewall without a hook. This simplified structure is tailored to fit tubeless tires, with the sidewall providing a tight seal and secure hold for the tire.

The hooked design features inward-curving lips along the inner edge. These lips form a groove that firmly grips the tire bead, ensuring stable mounting for various tire types, including clincher and tubeless options, even under high pressure.

Application Areas

Application areas for the W35X28TL carbon bicycle rim:

• Road Cycling:

The 35mm height of the rim, optimized for aerodynamics, and the 28mm external width that enhances tire grip make it an excellent choice for road cycling. Whether it's a flat road sprint or a long-distance ride, the lightweight carbon fiber material reduces energy consumption, allowing riders to maintain speed easily. The disc brake system ensures reliable braking even during high-speed descents, providing a safe riding experience.

• Mountain Biking:

The wave rim structure, which can disperse impact forces, and the durable full carbon fiber material enable the rim to withstand the bumps and vibrations of mountain roads. The 28mm external width offers good tire support, ensuring stable grip on rough and slippery surfaces. The hookless design, compatible with tubeless tires, reduces the risk of punctures, making it suitable for mountain biking in complex terrains.

• Commuting: 

For daily commuting, the rim's practicality is highlighted. The lightweight design makes it easy to maneuver in urban traffic.
