Look closely for scratches, especially anything deep or through the paint. With a dollar coin, tap on any suspect area and listen for a change in sound. A normal “tap” sound will become a dull thud when the carbon is broken. Gently push on the suspect area to feel if it’s softer than the surrounding area.
Can you ride a bike with cracked frame?
Riding on a cracked frame is risky as it could result in a catastrophic failure / injury / death. It looks like that’s probably a steel frame, so find a local frame builder ( not your buddy who’s handy with a welder ), and depending on the damage they may be able to repair it for you.
Is my carbon frame cracked?
If you can’t feel it with a fingernail, the crack probably isn’t in the carbon. Another trick is to whack the tube with a quarter over and around the crack. Do the same at a similar location that doesn’t have a crack. If there are any differences in sound, the frame has probably sustained damage.

Is a bike safe after a crash?
It’s not safe to ride a bike if the frame has been noticeably disfigured. Re-adjust the wheel to be aligned to the handlebars. The wheel tends to twist after crashes. Go through the final safety inspection you would normally go through, check the tyres, brakes.
Where do bike frames break?
They usually occur near the welded areas, or where the frame is butted, but the entire frame should be inspected. A common, and scary, place that frames crack is the underside of the down tube, just behind the headtube.
How does a bike frame crack?
Age is probably the main factor in a bike frame cracking. The older it gets, the weaker the material gets. The weaker the material gets, the more likely the frame is to crack.
What do you do with a broken bike frame?
Registered
- buy an inexpensive frame that will work with most (if not all) of the parts and build it up as a spare bike.
- take it apart and sell the parts or keep them around as spares.
- render the frame unuasable by sawing a chunk out of the frame donate the bike to a bike co-op.
Do carbon bike frames crack easily?
Carbon does not develop small cracks which could fail later like a steel or alloy frame might, by nature of it being a composite material.
How easy is it to damage a carbon frame?
Hansell says, ‘It’s quite hard to damage carbon “just a little bit”, so if it looks like a crack then chances are it is a crack. ‘Also, the elasticity of carbon fibre is usually less than the paint, so if the paint is cracked, there’s a high chance there’s been some kind of trauma to the carbon too. ‘
Can a cracked carbon frame be fixed?
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 epoxy 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.
