700C Best Carbon Rims for Road Bike 30mm Width 60mm Depth

Key Benefits of Carbon Fiber Road Bike Rims

Carbon fiber road bike rims are constructed from Japanese Toray T700/T800 carbon fibers, making them significantly lighter than traditional alloy rims. The reduced weight lowers rotational mass, improving acceleration and making climbing easier. The carbon fiber construction provides superior stiffness, giving riders more precise control and responsive handling during sprints, cornering, and high-speed descents. High-quality carbon materials ensure that these carbon road rims can withstand extended use and various road conditions, maintaining performance over time without compromising structural integrity. When paired with compatible brake pads, these rims offer consistent and reliable braking, enhancing rider safety and confidence on all road surfaces. With a 60mm depth and 30mm width, these rims are designed to minimize air resistance. The aerodynamic profile helps maintain higher speeds with less effort, ideal for racing and long-distance rides.

Performance Advantages of Carbon Road Bike Rims
Faster Acceleration
These carbon road bike rims use Japanese Toray T700/T800 carbon fibers, making them very light. Lighter rims help you start faster and pedal more easily uphill.
Better Aerodynamics
With a 60mm depth and 30mm width, these rims are designed to cut through the wind efficiently. The aerodynamic profile improves high-speed stability and reduces drag, providing a measurable performance advantage in racing and time trials.

Performance Testing of Carbon Rims Road

Rim UCI Impact Test
This test simulates the impact a rim may face during extreme riding conditions. With the rim set up without spokes, a vertical free-fall impact is applied directly to the spoke hole area, in accordance with UCI standards.
Result: The rim withstood the repeated impacts without cracks or structural damage, fully meeting UCI certification requirements.

Rim Positive Rigidity Test
Rigidity testing evaluates how the rim responds when subjected to vertical loads. In this test, the rim was mounted on a machine and subjected to increasing loads of 10 kg, 20 kg, and 30 kg. The corresponding deformation was measured at each stage, and the stiffness values were calculated.
Result: The rim achieved an average rigidity of 197.3 N/mm. The rim maintained stable stiffness across different loads, ensuring excellent responsiveness and stability for high-performance riding.
Walking Fatigue Test
The walking fatigue test simulates long-term riding conditions to evaluate rim durability under repeated impact. In this test, the rim was run at a constant speed of 40 km/h while the tire struck obstacles measuring 10 mm in height and 50 mm in width. The setup included a load of 64 kg, a swing angle of 5°, and tire pressure at 90% of the maximum rating. Over the course of the test, the rim experienced approximately 900,000 continuous impacts.
Result: After 12 hours and 58 minutes of testing, covering a distance of 535 km, the rim showed no abnormalities in its structure, tire mounting area, or outer circle. These results confirm the rim’s outstanding fatigue resistance and reliability for long-term cycling performance.
Rim Spoke Tension Test
Spoke tension testing ensures the rim can handle high spoke pulling forces during wheel assembly and real riding conditions. The rim was tested at multiple spoke tension levels up to 500–600 kgf.
Result: The rim withstood high spoke tension without abnormalities, proving its reliability in heavy-load and competitive environments.

Carbon Fiber Road Bike Rims Manufacturing Technology

Material Preparation
The process begins with selecting premium carbon fiber sheets. Each sheet is inspected for consistency, thickness, and fiber alignment before being precisely cut to size. This step ensures the structural integrity and performance of the final wheel.
Lay Up
Cut carbon sheets are carefully layered into molds according to a specific layup schedule. The fiber orientation is strategically arranged to achieve optimal strength, stiffness, and weight balance. Skilled technicians ensure every layer is placed without wrinkles or gaps.
Drilling
After preliminary shaping, precision drilling machines create accurate spoke holes and valve holes. This step demands high accuracy to ensure perfect spoke alignment and long-term durability under riding stress.
Molding
The mold is closed and heated under pressure. This bonds the resin and fibers together, creating the rim’s solid structure. The layered carbon is placed into a high-temperature, high-pressure mold. This molding process compresses the fibers and cures the resin, forming the wheel’s final structure while maximizing strength and minimizing weight.
Testing
Each molded rim undergoes rigorous quality checks. Dimensional accuracy, roundness, and structural integrity are tested by load and impact tests to confirm safety and performance.
Painting
A protective coating or custom paint is applied, giving the wheel its final look and extra protection against the elements. After passing tests, rims enter the painting and finishing stage. Here, protective coatings and custom graphics are applied. This not only enhances the aesthetic appeal but also provides UV and weather resistance.
QC Test
Every rim undergoes strict dimensional, strength, and balance testing. Wheels are carefully packed using protective foam and custom-fit boxes to prevent any damage during transport. This ensures they arrive at customers in perfect condition.
Packing
Rims are securely packed to prevent damage during shipping. Wheels are carefully packed using protective foam and custom-fit boxes to prevent any damage during transport. This ensures they arrive at customers in perfect condition.
Shipping
Finished carbon road wheels are shipped worldwide via air, sea, or land logistics, ready to deliver top-tier performance to cyclists across the globe.
