Product Features and Advantages

Outstanding advantages of carbon fiber material:

Made of high-quality Toray carbon fiber from Japan, it weighs only 320g at the minimum. Compared with traditional metal rims, it is lighter, and at the same time, it has both high strength and excellent fatigue resistance. It can resist impact, maintain structural stability, prolong service life and reduce replacement frequency.

Strong adaptability and stable performance:

The precise design with 35mm height, 28mm external width and 21mm internal width is suitable for various tubeless tires, which can be stably installed without additional adjustment. Relying on the rigidity of carbon fiber and reasonable size, it can reduce shaking and deformation during high-speed riding and under complex road conditions, improve stability and controllability, and reduce the risk of air leakage.

Efficient supply ensures timeliness:

The factory has a large stock, which can quickly respond to various order demands and avoid waiting due to out-of-stock. With 10 years of professional production experience, it has formed an efficient operation system, and the process from order receiving to delivery is smooth, shortening the delivery cycle and ensuring that customers can get the products in time.

Rich and diverse customization services:

Various customizations are provided around carbon fiber materials, including the number of spoke holes, carbon fiber patterns, exclusive labels, as well as customized matching carbon fiber rims and spokes, so as to realize the personalized configuration of the whole wheel set and meet unique style and performance needs.

Professional production with reliable quality:

The factory has been focusing on the production of carbon fiber bicycle rims for 10 years, and has a good command of material processing technology and performance control. It strictly controls the quality during the production process, and the quality and craftsmanship of the produced rims have a good reputation.

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

Rim Body:

As the core part, it is crafted from layered carbon fiber sheets. These layers are meticulously arranged and bonded together, leveraging the high tensile strength of carbon fiber to provide robust structural support. The layered design not only enhances the rim's rigidity to withstand riding pressures but also contributes to its lightweight property, which is crucial for reducing overall wheel weight and improving riding agility.

Spoke Holes:

Precisely drilled at equal intervals around the rim body, these holes are engineered to ensure a secure and stable connection with spokes. The drilling process is carried out with high precision to maintain the integrity of the carbon fiber structure, preventing cracks or damage. By evenly distributing the tension from the spokes across the rim, they help keep the wheel in proper shape, ensuring smooth rotation and balanced weight distribution during rides.

Edge Lips:

Located on both sides of the rim's outer edge, these lips are specifically designed to work with tubeless tires. Their shape and dimensions are optimized to create a tight seal with the tire beads, effectively preventing air leakage and ensuring airtightness. Additionally, they firmly lock the tire in position—even during high-speed rides or sudden maneuvers—to avoid slippage.

Application Areas

Application areas for the D30X28TL carbon bicycle rim:

• Road Racing:

In competitive road racing, where every second counts, the ultra-lightweight property of this rim minimizes rotational mass, allowing for rapid acceleration and sustained high speeds. Its high rigidity ensures that every bit of pedaling force is efficiently transferred to forward motion, critical for sprints, breakaways, and maintaining pace in pelotons. The precise dimensions (35mm height, 28mm external width, 21mm internal width) also contribute to aerodynamic performance, reducing air resistance during high-speed rides.

• Time Trials and Triathlons:

 These events demand maximum efficiency over a set distance. The rim's lightweight design reduces fatigue for riders, who need to maintain intense effort for extended periods. Its stable structure, paired with tubeless tire compatibility, ensures consistent rolling resistance, helping athletes achieve their best times without worrying about tire-related disruptions.

• Long-Distance Road Riding:

For endurance rides, such as century rides or multi-day tours, the rim's durability and comfort come into play. The carbon fiber material absorbs minor road vibrations, reducing rider fatigue over long distances. Its lightweight nature eases the strain on legs during climbs and long stretches, while the secure tire hold from the edge lips ensures reliable performance even when covering hundreds of kilometers.

• Training and Recreational Road Cycling:

Even for non-competitive riders focused on training or leisure road rides, this rim enhances the experience. It makes the bike more responsive to handling, whether navigating winding country roads or urban thoroughfares. The reduced weight makes daily training sessions less strenuous, and the stable performance inspires confidence in riders of all skill levels.
