Frequently asked questions

Most cracks, crushed tubes, dropped-chain damage, delamination, and even fairly serious crash damage are repairable. What isn't repairable is a frame where the geometry itself has been bent or where damage is so extensive across multiple tubes that a rebuild would cost more than the frame is worth. When in doubt, send photos — we'll give you a straight answer, and it costs nothing to ask.

Cracks, impact damage, delamination, crushed tubes, dropped-chain and dropped-derailleur damage, bottom bracket shell damage, dropout damage, seat-stay and chain-stay breaks, head-tube damage, and more. If you're unsure whether your specific damage qualifies, send us photos and we'll tell you.

On its own, a structural repair will show some texture or a color difference where new laminate meets old, since we don't skip steps to hide it. If that matters to you, pair the repair with a refinish — we blend the repaired area into the surrounding paint so it disappears completely, whether that's a factory color match or a fresh custom finish.

Yes. We don't consider a repair finished until the laminate is rebuilt to match the original fiber orientation and layer count in that area — the same engineering logic used in aerospace composite repair. Every structural repair we complete is guaranteed, and in more than 2,000 repaired frames we have had zero structural failures.

Carbon forks, yes — fork damage is common and often repairable using the same process as frame repair. Handlebars, seatposts, and wheels are more case-by-case: some carbon components are load paths that are too thin-walled or too safety-critical to responsibly repair. Send photos of the specific part and we'll tell you honestly whether it's a candidate.

We work around it, not through it. Internal housing and wires are pulled clear of the repair area before we cut out damaged laminate, protected during the layup and cure, and re-routed before the frame ships back. If a repair sits directly on a cable port or guide, we rebuild that feature into the new laminate so routing works exactly as it did before.

Most manufacturer crash-replacement and warranty programs only cover the original defect or damage they define — a repaired frame typically isn't eligible for further manufacturer warranty claims on the repaired area regardless of who does the work. If your frame is still under an active manufacturer warranty for unrelated defects, check with the manufacturer before you have any repair done, by us or anyone else.

Yes. We spray matte or gloss finishes in any color, including custom color matching when the manufacturer doesn't publish the original color codes — common on older or discontinued frames. Multi-color schemes, fades, and logo or graphic reproduction are all part of the standard refinishing service.

In most cases, yes. We color-match from the existing paint on your frame or from clear reference photos, and we can reproduce factory graphics and logos. Exact metallic flake or pearl effects can vary slightly by lighting and viewing angle, which is true of any repaint on any material — but we aim for a match close enough that it isn't obvious which side got touched.

Box the frame — a bike shop can usually give you a free bike box — remove pedals, skewers, and anything easily lost or damaged in transit, and protect the frame with foam pipe insulation or similar padding at the tubes, especially near the damaged area. Ship via a trackable carrier to our Walworth, WI address. See the shipping page on this site for a full packing walkthrough.

Shipping to us is on the customer, and we'll confirm return shipping costs as part of your quote. We ship completed frames back well-packed and with tracking, and we're happy to advise on the most economical way to send a bike box if you're shipping for the first time.

Carbon fiber offers the best strength-to-weight ratio available for bicycle frames, and unlike a metal tube, its properties can be tuned ply by ply — engineers can add stiffness in one direction while allowing compliance in another. Done right, a carbon frame is lighter, stronger in its designed load paths, and rides better than a comparable metal frame.

A carbon frame is built up from multiple plies of carbon fabric, many of them unidirectional — meaning the fibers in that layer only run one way. Layers are stacked and oriented at specific angles, commonly around plus-or-minus 45° or 60°, chosen to control stiffness and strength in each direction the frame needs to handle load. Our repairs are done to respect that original layup, not just fill a hole with resin.

The large majority of damage we see is impact-related: crashes, a rock kicked up into the down tube, a dropped chain crushing the chainstay, shipping damage, dropped tools in the garage, or an over-torqued clamp on a seatpost or stem. Carbon is extremely strong along its designed fiber direction but is far more vulnerable to sharp, localized impacts perpendicular to those fibers — which is why a small-looking dent can hide a larger crack underneath.

Bicycle frames are the core of the business, but the composite repair expertise behind them isn't bicycle-specific — the shop's background spans marine, automotive, and aerospace composite structures, and we take on repair work for carbon components from those worlds as well. If you have a damaged composite part that isn't a bike frame, get in touch with photos and we'll tell you honestly whether it's something we can help with.

Email or call us with photos of the damage, or use the contact form on this site. For anything you're unsure about, shipping the frame in for a hands-on look gets you the most accurate answer. Either way, quotes are free and there's no obligation to move forward.

It depends entirely on the frame: the size and location of the damage, how many tubes are affected, and whether you're adding a refinish. Small, localized structural repairs tend to run in the low hundreds of dollars; extensive structural work or multi-color custom refinishing costs more. We give every customer a firm, written quote before any work starts — there are no surprise charges after the fact.

We'll send a quote once we've assessed your frame, and payment is arranged directly with us by phone or email — typically once you approve the quote and again before the frame ships back. We can walk you through the specifics when we send your quote.

It happens occasionally — usually when damage extends further than photos suggested, or the frame's geometry itself was bent in a crash. If that's the case, we'll contact you before doing anything further, explain exactly what we found, and either return the frame to you or dispose of it, whichever you prefer. You won't be charged a repair fee for a frame we can't fix.
