Since carbon fiber essentially does not fatigue as long as the carbon-and-resin matrix is not damaged, age alone is not much of a guide. What matters are impacts big enough to delaminate or crack. Appleman Bicycles can repair your damaged, broken, busted, or cracked carbon fiber frame. I've been fixing carbon fiber for over 10 years and have a deep understanding of advanced composite structure repair. I started my career building and repairing wind-turbine blades before moving on to aerospace and then bikes. What you’ll see is some small dots of resin passing through the perforated film. This is excess resin of the saturated carbonfiber cloth that is being absorbed by the breeder. Check for leaks, once you have full vacuum let the pump on for 15min than clamp of the hose and shut down the pump.

Carbon Frame Repair Review

'My Carbon bike frame got a hole in the seat tube from a bolt failure. Don's Bicycle did a great job repairing it. They were reasonable on cost and quick with repair. Thanks for great Service!'

-Chuck Horne

Can you fix a Carbon fiber bike that is cracked or broken?

Yes, you can! The process of repairing a carbon fiber bike frame that is cracked, damaged, or split is to lay new carbon fibers and epoxying them in the same direction as the original fibers. The end result is a stronger bicycle frame than the original build at a negligible weight gain.

We've helped tons of folks in our local and massive California cycling community (We're located in Rialto, CA) get back on the road after their bicycle frames sustained damage. Our customers were really excited about the quality of the work, on both the actual frame repair and the finish quality of the paint job. You can see example jobs below.

Carbon Fiber Bike Frame Repairs

Do you need to get your carbon fiber bike frame repaired? Are you wondering if it is possible to get that crack in your frame repaired?

Cracks Happen

Carbon Fiber frames offer so many upsides for biking. They're lightweight, stiff, and in many ways, super strong. They can crack, break or fail though if the frame gets dinged in the wrong place, or if you were just unlucky.

Recent Frame Repairs include:

Cracked Downtubes
Damaged Top Tubes
Cracked Seatstays and Broken Chainstays
Cracked Headtubes
Damage sustained due to Car Rack Snafus.

The price is determined by the type and severity of the break. and complexity of paint scheme.

How To Tell If A Carbon Fiber Bike Frame Is Cracked

We'll remove all components from your frame in order to complete the repair and then professionally build your bike after the repair is completed.
If you ship us just the frame, this fee will be waived.

How does Payment Work?

Great Question! When the work is complete on your bike, we will send an invoice via PayPal. Once the invoice is paid, we'll ship it back to you

How much weight will the repair process add to my frame?

We typically see negligible weight gain with an average of less than 12g of additional weight.

How will my bike ride when you're done?

We line up the carbon fibers in the same direction as your frame and keep the same shape as your frame thus leading to a ride that is the same as before the frame damage occurred.

What types of Frames and Brands can you fix?

If it's a Carbon frame and it's broken we can fix it. We routinely repair all types of frames (Mountain Bikes Road Bikes and Cyclocross bikes). We also repair all brands of carbon frames.

Do you repair Carbon Fiber Bike Parts?

That is another great question and the answer is no, we don't. We don't fix carbon fiber seat posts, cranks, wheels, and handlebars because the replacement cost of the part is often far lower than the cost of repair. We say go for the new part in that situation. We don't repair wheels (even though the replacement cost is higher than the repair) because the forces exerted on the rim and the need to get the wheel balanced perfectly preclude a carbon fiber repair.
