Features of Carbon Rims for Gravel Bike
Lightweight and Strong: The frame is made of aerospace-grade Toray T700/T800 carbon fiber, with a precision-engineered laminated design. During your full-throttle sprint, it provides surgical-like rigidity feedback, ensuring every bit of power is efficiently converted into driving force.
Shock Absorption Control: Carbon fiber itself possesses natural shock-absorbing properties, effectively filtering out rough road surfaces and minor vibrations as if it were "swallowing" bumps.
Optimized Aerodynamics: Through rigorous wind-tunnel testing and computational fluid dynamics simulations, we've sculpted a highly efficient drag curve. It cuts sharply through the air in straight lines, while its clever design maintains a stable handling trajectory when encountering crosswinds, allowing you to remain calm and composed in any environment.
Tubeless Tire System: Compatible with tubeless tire systems, it's the gateway to a superior riding experience. You can safely use lower tire pressures for a larger contact patch and "railcar-like" grip.

How to Choose Rim Width & Depth for Gravel Tires
Choose a Width Based on Tire Support
Start with the rim inner width. It controls how your tire sits and how stable it feels when you lean the bike. A rim that’s too narrow can make the tire feel tall and vague in corners. A wider rim gives the sidewalls better support, which helps when you run lower pressure on rough gravel.
Pick Depth Based on Your Terrain
Rim depth changes the balance between comfort, stability, and wind behavior. Shallower rims are a safe choice for rocky roads and mixed surfaces. Deeper rims can feel firmer and hold speed better on smoother sections, but they can react more in crosswinds.
Simple Selection Tips
Riding chunky gravel with bigger tires? Choose a wider inner width.
Want one wheelset for most rides? A mid-depth rim is usually the easiest fit.
Spend time on open, windy roads? Don’t go too deep unless you like how deep rims
handle.
Testing of Carbon Gravel Rims
UCI Impact Test: Simulates sudden impacts such as potholes or curbs to
verify impact resistance.
Road Fatigue Test: Applies repeated loads to replicate years of riding
stress and confirm long-term reliability.
Rim Longitudinal Stiffness Test: Measures the balance between
efficient power transfer and riding comfort.
Spoke Hole Tension Test: Checks each spoke hole's ability to
withstand high tension without deformation or cracking.

Carbon Gravel Rims OEM Customization Options
Drilling, ERD, and Build Compatibility
You can customize spoke hole count, drilling angle, and nipple bed details to match your hub and lacing plan. ERD can be confirmed for your build sheet, so spoke length calculations stay consistent across batches.
Rim Profile and Width Options
You can choose different inner widths and depths based on your tire targets and riding focus. If you’re building an all-round gravel line, we can help you map width/depth options into clear SKUs instead of overlapping models.
Rim Type and Tubeless Details
Hooked or hookless can be selected by project, along with tubeless-ready details like tape bed design and valve hole specs.
Finish and Branding
You can select UD, 3K, or other appearance options (model-dependent), plus gloss or matte clear coat. Branding can be added through decals or private-label marking, with placement matched to your design guidelines.
Labels, Packaging, and QC Alignment
You can request barcodes, model labels, and batch traceability marks to support your warehouse process. Packaging can be set up for bulk shipment or assembly-friendly packing to reduce handling marks. If you have an incoming QC checklist, we can align key inspection points before production.
FAQ
Q: What are carbon fiber0 gravel rims? How are they different from road rims?
A: Carbon fiber gravel rims are designed for mixed-terrain riding, combining the lightweight of road rims with the strength of mountain bike rims. They have a wider inner width (typically 24-28 mm) to accommodate gravel tires up to 50 mm, providing better grip and comfort on rough terrain.
Q: Are carbon fiber gravel rims durable enough for rough terrain and gravel roads?
A: Yes. Our rims are made from Toray T700/T800 carbon fiber and undergo rigorous shock and fatigue testing. They are carefully designed to withstand the vibrations, minor impacts, and uneven surfaces common in gravel riding.
Q: Can I use tubeless tires with carbon fiber gravel rims?
A: Absolutely. All our carbon gravel rims are designed for tubeless riding, meaning you can run at lower tire pressures for better traction and fewer punctures. This is a major advantage for off-road and endurance riding.
Q: Which tire width is best for carbon gravel rims?
A: The ideal range is 35–50mm. Narrower tires (35-38mm) are suitable for fast gravel or mixed road riding, while wider tires (45-50mm) provide extra stability and comfort on soft or rocky surfaces.
Q: Are carbon gravel rims compatible with disc brakes?
A: Yes. Most modern gravel bikes use disc brakes, and our carbon fiber rims feature reinforced sidewalls and spoke holes designed specifically for disc brake hubs.
Q: How should I maintain my carbon gravel rims?
A: After muddy or dusty rides, keep the rims clean, avoid using strong cleaners, and check spoke tension regularly. For tubeless systems, change the sealant every 2-3 months.
Q: What is the load limit for carbon gravel rims?
A: Our rims can safely support up to 120 kg of rider + gear total weight. For heavy touring or electric gravel riding, we recommend 32-hole rims for added strength.
Q: Do you offer OEM or branded customization services for carbon fiber gravel rims?
A: Yes. We offer OEM, logo printing, and custom sticker services. Rim depth, number of holes, and weave texture (unidirectional/triple/twill) can all be customized to match your brand image.
Q: Is there a risk of overheated brake pads on carbon fiber rims? Should I choose disc brakes or rim brakes?
A: For gravel bikes, choose disc brakes without hesitation.
Absolute safety: On long downhill sections, using rim brakes on carbon fiber rims does
pose a risk of overheating brake pads, resin carbon cloth failure, or even tire blowout
due to prolonged braking. Gravel roads are often accompanied by unpredictable, sharp
bends and steep slopes, and disc brakes (especially hydraulic disc brakes) can provide
a stable, powerful braking force that is unaffected by weather and road conditions.
