What are 700C Carbon Road Rims?
Carbon fiber road bike rims are bicycle wheel frames made primarily from carbon fiber composite materials. They are formed by arranging and curing carbon fiber tows (usually combined with resin) into a specific structure. They combine lightweight, high strength, and high rigidity. Custom sizes and specifications are available, and ODM and OEM options are welcome.

Features of Carbon Road Rims
Lightweight and Sturdy
Our carbon road rims are made from premium Japanese Toray T700/T800 carbon fiber, offering a perfect balance of lightness and strength. This helps you accelerate faster, climb easier, and maintain speed more easily.
Aerodynamic Design
The rim profile is designed to reduce air resistance, allowing you to ride more efficiently on flat surfaces and in crosswinds.
Long-Lasting Performance
Carbon rims resist corrosion and wear, so they stay in great shape for years. With proper care, they'll outlast many traditional options.
Consistent Performance
Each rim is meticulously crafted to ensure smooth handling and reliable braking.
You'll experience these key benefits on every ride:
Lighter weight for faster climbs.
Improved aerodynamics for more speed.
Strong construction for durability.
Smooth braking performance on both wet and dry roads.

Applications Of Carbon Rims Road Bike
● Road Racing
If you're a road racer, carbon fiber wheels will give you an advantage. Their lightweight design helps you climb faster and maintain speed on the flats. You can rely on them in races where the clock is ticking, such as criteriums, road races, and time trials.
● Endurance Racing and Training
These wheels are also perfect for long-distance rides. Their lighter weight reduces fatigue, making long training sessions easier. Riders can enjoy smooth handling and stable performance on long road rides.
How Are Carbon Fiber Road Bike Rims Produced?
Selected Materials
Premium Toray carbon fiber tows are chosen, and precisely cut and pre-impregnated according to the rim design specifications. Each fiber layer (0°/±45°/90°), weight, and thickness is accurately matched to the structural stress requirements.
Precision Layup
Experienced carbon fiber technicians hand-lay the prepreg material layer by layer onto a high-precision mandrel. Each layer is placed strictly according to the predetermined angle and sequence, assisted by laser projection to ensure a layup angle deviation of less than ±1°.
Autoclave Curing
The preform is placed into a high-precision autoclave and cured at 135°C and 0.6 MPa for 90 minutes under constant temperature and pressure. This ensures the resin fully impregnates the carbon fibers and crosslinks evenly, forming a dense structure without bubbles or delamination.
Demolding and Initial Finishing
After curing, the rim is carefully removed from the mold using a hydraulic system. Technicians manually remove flash and burrs with diamond grinding tools and perform coarse polishing on the surface to prepare for final finishing. The entire process is conducted in a Class 1,000 cleanroom to prevent dust contamination.
Precision Machining & CNC Forming
Five-axis CNC machines perform high-precision machining on the rim, including drilling spoke holes, valve hole positioning, and inner diameter finishing.
Surface Treatment & Customization
A multi-layer coating process is applied: first an epoxy primer for adhesion enhancement, followed by a high-performance polyurethane topcoat (available in matte, semi-gloss, or glossy finish). Customization can be done according to client requirements.
Comprehensive Quality Inspection
Each finished rim undergoes rigorous testing:
Coordinate Measuring Machine (CMM): Verifies rim geometry (radial/lateral runout ≤ 1.0 mm)
Dynamic Balancing Test: Ensures stability at high speeds
Hydraulic Burst Test: Simulates extreme conditions to check rim strength
Fatigue Test: Simulates tens of thousands of pedal cycles
Coating Thickness Measurement: Ensures uniform surface protection
Professional Packaging & Delivery
Qualified carbon road rims are packaged with anti-static foam padding and custom corrugated boxes for double protection, and delivered globally by a professional logistics team with full tracking to ensure safe arrival.
