Our proven process removes the fear from carbon fiber repair

Assessment

Before we do anything to your bike, we'll assess the extent of the damage

Carbon Repair

Then we remove bad carbon and replace with new structurally perfect repair

Original Aesthetics

Lastly, we restore the bike to its original aesthetics in our custom paint shop

Damage Assessment

After we receive your frame we will assess the extent of the damage. We frequently run broken frames under our Ultrasonic Scanner to ensure that we fully understand the damage.

Once we understand the extent of the damage we will create a plan to repair the damage.

Engineering the repair

Not all carbon fiber damage is the same. We assess the damage and its impact on the structure, then engineer a repair to restore the structural integrity and appearance of your frame.

We make zero compromises in that work, even when it means acquiring new tools to get the job done right.

Repairing Carbon Fiber

We have been repairing carbon fiber for over a decade and we take great pride in bringing your bicycle back to its original condition. This means that the repair can’t just be strong but it has to look like it came from the factory too.

When TWCarbon repairs your frame, no one will ever know that there was damage in the first place.

TWCarbon Frame Painting

After the broken carbon on your bike is repaired, we send your frame over to our Custom Frame Paint shop.

With great care taken to the shape of the carbon fiber repair our paint team is able to color match your frame and restore the damaged area to the original appearance.

Our goal is that not even you will be able to spot the repair.

Ultrasound inspection of a cracked carbon fiber bicycle frame

Proof, Not Promises: Every Repair Can Be Verified by Ultrasound

The scariest thing about a repaired frame is what you can't see. That's why we use the same ultrasonic scanning technology used to inspect aircraft parts. Before the repair, the scan maps the true extent of the damage, including cracks and delamination hiding under paint that looks fine.

After the repair, the scan shows the new laminate is fully bonded to the original structure with no voids, no dry spots, and no damage left behind. You don't have to take our word that the frame is sound; the scan shows it.

Learn more about our ultrasound inspection service, also available as a stand-alone check for frames that haven't been repaired.

What a Carbon Repair Costs

Real prices, straight from the shop. Every repair starts with a $250 minimum, and full tube replacements start at the prices below.

Repair	Starting at
Minimum for any repair	$250
Full seat stay replacement	$850
Full chain stay replacement	$1,100
Full top tube replacement	$1,300
Full down tube replacement	$1,600
Quick-release rear dropout replacement	from $650
Thru-axle rear dropout replacement	from ~$1,000

What makes a repair cost more: Repairs that run into a corner (or involve the bottom bracket, headset, head tube, or seat clamp area) cost more than a straight mid-tube repair.

Every frame is different, so exact quotes come from photos and inspection. Send a few pictures of the damage and we’ll give you a real number.

Not Local? Ship Us Your Bike

Many of the frames we repair arrive by mail. If there’s no qualified carbon repair shop near you, shipping your frame to Kirkwood, MO is how riders all over the country get their bikes fixed.

1

Get your quote first

Send photos of the damage through the quote form. You’ll know the estimated cost before you box anything up, with no surprises after the frame is already in the mail.
2

Strip and pack the frame

Remove your components (or have your local shop do it), clean the frame, and pack it the way it shipped from the factory: padding around every tube, nothing loose in the box. A bike box from a local shop works great.

Ship with any major carrier and insure the package for the value of the frame. We’ll confirm the moment it arrives.
4

We check it in and keep you posted

On arrival we photograph and inspect the frame, confirm the plan against your quote, and send updates as the repair progresses.
5

It comes back ready to ride

When the repair is done and verified, we pack the frame the same careful way and ship it back to your door.

Carbon Repair Questions, Answered

Are carbon fiber bikes repairable?

Yes. In most cases a damaged carbon frame can be fully repaired. We remove the damaged fibers and rebuild the area with new carbon matched to the original layup. We’ve brought back everything from hairline cracks to fully broken-through tubes.

Is a repaired carbon frame safe to ride?

That’s the right question to ask, and we answer it with evidence instead of promises. Every structural repair can be verified with an ultrasound scan, which shows the new laminate is fully bonded with no voids or hidden damage left behind. You see the proof before the bike goes back under you.

How much does it cost to repair a carbon fiber frame?

Every repair starts at a $250 minimum. Full tube replacements run from $850 for a seat stay up to $1,600 for a down tube, and repairs into corners or around the bottom bracket, headset, head tube, or seat clamp cost more. Send us photos and we’ll quote your exact damage.

Is it worth repairing a carbon bike frame, or should I buy new?

Usually, yes. A repair is typically a fraction of the cost of a comparable new frame, and it keeps the bike you already know and love. When replacement genuinely makes more sense for your frame, we’ll tell you that up front.

How long does a carbon fiber repair last?

A properly executed repair becomes a permanent part of the frame: new carbon bonded and cured into the surrounding structure. It doesn’t wear out on its own schedule, and we can verify the finished repair with ultrasound before the frame leaves the shop.

How long does a repair take?

The carbon work itself usually takes 10–12 business days once your frame is in the shop. If the repair includes paint matching, plan on another 3–5 weeks. Most bikes are back on the road in 4–6 weeks.
