Integrated Mounting Options: Designed with versatility in mind, carbon gravel frames include mounts for racks, fenders, top tube bags, and multiple water bottles - ideal for bike packing, commuting, or ultra-distance adventures.
Engineered Comfort & Compliance: Tuned carbon layups and flex-optimized seat stays and fork blades help soak up vibrations and bumps, delivering a smoother, fatigue-reducing ride on rough terrain.
Balanced, All-Terrain Geometry: Blending road-bike speed with off-road stability, the geometry offers agile handling for tarmac while staying confident and planted on gravel, descents, and climbs.
Clean Internal Cable Routing: Keeps brake and shift cables hidden inside the frame for a streamlined appearance, reduced maintenance, and better protection from dirt, water, and debris.
Lightweight and Strong: Full carbon construction is stiff and lightweight, allowing riders to efficiently transfer power without sacrificing ride quality.
Carbon Gravel Frames Production Steps
1. Design & Engineering Development
The geometry of each frame is carefully tailored according to the client's specific requirements, including key parameters such as head tube angle, chainstay length, and bottom bracket drop. Every measurement is optimized to deliver the best possible balance between performance, comfort, and terrain adaptability.
2. Carbon Fiber Cutting & Lay-Up
We use Toray carbon fiber prepreg materials, which are precisely cut based on lay-up schedules provided by our engineers. Skilled technicians then manually lay each carbon sheet into the mold layer by layer. Different grades of carbon fiber are applied strategically in various parts of the frame to achieve optimal stiffness, strength, and compliance.
3. High-Temperature Curing & Molding
Once lay-up is complete, the mold is placed into a high-pressure autoclave oven for thermal curing. Under controlled temperature and pressure, the epoxy resin within the carbon layers flows and hardens, bonding the fibers together and forming a seamless, high-strength monocoque frame structure.
4. Demolding, Sanding & CNC Drilling
After curing, the carbon gravel frame is carefully removed from the mold. Our technicians perform precise sanding to smooth out the edges, curves, and joints for a seamless finish and excellent tactile feel. All necessary holes-such as for the bottom bracket, headset, bottle mounts, and internal routing, are drilled with CNC equipment to ensure exact placement and tolerance.
5. Painting & Surface Finishing
According to client preferences, we apply custom paintwork, decals, and graphics to the frame. The finishing process is carried out in a dust-free, climate-controlled room to ensure even application and proper curing. From matte finishes to exposed carbon weave or custom colorways, we deliver premium-level visual presentation tailored to each brand's identity.
6. Quality Control & Testing
Each finished frame undergoes a full quality assurance protocol, including:
Geometry and dimensional inspection
7. Weight verification
Structural fatigue and impact resistance tests, simulating real-world riding stress
Internal cable routing checks to ensure smooth passage without burrs or obstruction
The geometry of a carbon fiber gravel bike frame is designed to provide a versatile, comfortable ride that is suitable for both road and off-road riding.
Longer Wheelbase: A longer wheelbase provides more stability at high speeds and on rough terrain. This helps maintain control when descending and traversing technical sections.
Slacker Head Tube Angle: A slacker head tube angle (usually around 70-71 degrees) improves front wheel stability and makes the bike more forgiving on descents and rough terrain.
Lower Bottom Bracket: A lower bottom bracket lowers the center of gravity, enhancing stability and control on uneven ground, especially on rough pavement.
Budget: First, choose the type of carbon fiber. T700 is durable and affordable, while T800 or higher grades are stronger and lighter, which improves efficiency.
Frame Size: Choosing the right frame size is crucial. The frame size should match your height, leg length, and riding position. The right size can improve riding comfort and efficiency, and reduce the risk of injury
Compatibility: Make sure the frame is compatible with your other riding equipment (such as wheels, gear systems, brake systems, etc.). Some frames may require specific accessories or adapters.
Geometry: Endurance frames have a more relaxed head tube angle and a longer wheelbase, providing greater comfort and control on rugged terrain
Built For Brands
Launching a new gravel line or upgrading an existing platform? Our OEM/ODM frames help you shorten development time with consistent sizing, reliable compatibility, and stable finish quality.
Customization Beyond Paint
Choose paint, logo placement, decals, and matte/gloss finishes. Frame kits can be configured with items like forks, seatposts, thru-axles, and clamps. For tire clearance, routing (mechanical/electronic), or bottle/rack mounts, share your build plan, and our engineers will confirm feasibility for mass production.
Clear Specs, Fast Quoting
Each model comes with a standardized spec sheet covering weight range/tolerance, axle standards, BB type, brake mount, and routing—making sampling and repeat orders easier.
Qc That Protects Your Reputation
We check appearance, key dimensions, threads/mounting points, and alignment before packing, and can provide inspection photos or records if needed.
Global-ready Delivery
Standard protective packaging is included, with reinforced export options available. Send your target market, volume plan, and timeline, and we’ll match supply to your launch schedule.
Test Of Carbon Frame
Why testing matters: A carbon gravel frame is only as good as its consistency. You want a frame that rides the same on day 1 and after thousands of rough miles.
Material & layup checks: We verify carbon fabric batches, resin control, and layup accuracy to reduce weak spots and uneven stiffness.
Dimensional inspection: Key interfaces—head tube, bottom bracket, dropout spacing, and brake mounts—are measured to ensure clean assembly and stable alignment.
Strength & fatigue focus: Frames are evaluated for impact resistance and long-term fatigue performance, not just “lightweight” numbers.
Final QC: Every frame receives a finish inspection to catch surface defects before packing, so you get a build-ready frame, not a surprise.
FAQ
Q: Does it support UDH? What does UDH mean for me?
A: If your derailleur/rear hanger setup prioritizes universal compatibility and ease of maintenance, UDH will be more convenient. You need to confirm compatibility with your specific model and rear derailleur system.
Q: What is the weight? Why do I see different weight data in different places?
A: Weight must be specified by "model + size + whether hardware is included." The page will clearly state the weight range and tolerance of the frame in the specifications table for each model to avoid confusion.
Q: Can I customize the paint and logo? What do I need to provide?
A: Yes. You typically need to provide the logo file (AI/PDF), color reference, surface finish (matte/glossy), and decal placement requirements. We will provide a rendering for your confirmation first.
Q: What tire sizes are suitable for this carbon fiber gravel wheelset?
A: Our carbon fiber gravel frame supports tires up to 700x45c or 27.5x2.1 inches, providing excellent grip and comfort on various road conditions.
Q: Is the frame compatible with UDH?
A: Yes. This frame is fully compatible with the Universal Derailleur Hanger (UDH), ensuring better drivetrain alignment and future compatibility.
Q: What is the weight of the frame?
A: The medium-sized frame weighs approximately 1050 grams (±30 grams). The exact weight depends on the surface finish process. It's light enough for racing and strong enough for adventures.
Q: What is the difference between T700 and T800 carbon fiber?
A: T800 carbon fiber is stiffer and lighter than T700, providing better power transfer and responsiveness. T700, on the other hand, offers greater comfort and durability.
