Matt Appleman Repairing a carbon fiber bike

Carbon Bike Repair

Appleman Bicycles can repair your damaged, broken, busted, or cracked carbon fiber frame! Nearly every carbon fiber frame can be repaired no matter how severe the damage.

I've been fixing carbon fiber for over 10 years and have have a deep understanding of advanced carbon structure repair. I started my career building and repairing wind-turbine blades before moving on to aerospace and then 🚲 !

It's a myth that carbon can't be repaired. In fact, carbon fiber is one of the most repairable materials and each Appleman repair is covered by a 10 year warranty! Repairs are slightly stronger than the pre-damaged frame, add no measurable weight, and don’t alter the ride of the bike.

Raw/No-Paint Finish
Ride that battle-scar proudly! I use only the best UV protected epoxy and carbon fiber. Appleman repairs are as durable as a painted repair, but won’t scratch and chip like paint will. Raw finishes require no maintenance.

To get you back on your bike as quickly as possible, repairs are left smooth with a nude carbon fiber finish with no paint.

A bit of background on this pic... Tobin and Team Donkey Label were racing at the North Star Grand Prix. Tobin crashed heavily in the road race and damaged the top tube. He didn't have an extra bike and repair was the only option. The team brought the bike to the Appleman shop and within 4 hours the bike was repaired and back in Tobin's hands for the crit that afternoon!

Repair FAQ's

How strong are repairs?
Repaired areas of the frame are stronger and tougher than the original frame. I use my expertise to evaluate each repair, rebuild it and improve upon the existing carbon fiber layups to maximize strength and durability.

How durable are repairs?
The repair will outlast the rest of the bike.

Do I need to remove all the components from my bike?
No! I need clear access around the entire damaged tube. Often, this is as simple as moving a cable, or removing the crank. Often times, nothing needs to be removed! I try and make it as simple as possible for you. When shipping your bike, I recommend removing as many components as practical to reduce shipping cost and minimize the possibility of damage.

What is your repair warranty?
Appleman offers a 10 year warranty on carbon fiber repairs. Work involving metal like adding cable stops or water bottle bosses are not covered under warranty.
