CARBON REPAIR SYDNEY
Theres alot of missconception around carbon repairs and its no surprise that safety is a big concern when youre flying down a hill at 90kph in a 60zone on a tringlular piece of carbon.
Colourfuel conducted over 100 carbon repairs in 2022 alone. So we asked our carbon guy some questions to find out more about carbon frame repairs.
What’s your background?
I have been in the cycling industry since 2001 with carbon repairs starting in 2006. This has given me the opportunity to see how the carbon fibre technology has changed from the very first carbon bike frames and components all the way through to what we see today.
In 2012 I made a move over to the defence sector working with composite ballistic armour. Since then I have worked designing, engineering and manufacturing various forms of composite ballistic armour systems. This has given me an incredibly advanced knowledge of the failure mechanisms of composite materials.
I also have been known to produce custom sporting equipment using carbon fibre such as time trial handlebar, frames, shoes along with support devices.
What can be repaired?
Are carbon repairs safe?
When repaired by someone with a high degree of knowledge performs the repair, I would argue that the repaired area would have a higher degree of workmanship than what comes out of the factory. Most frame these days are made by a handful of factories in either China or Taiwan, mass produced by relatively low skilled labour. Most production frames contain a certain number of manufacturing defects from voids in the laminates to resin heavy pockets. That’s not to say that these frame and components are unsafe, you rarely see catastrophic failures out in the real world, just a reflection on the manufacturing environment.
With my repairs, I use higher quality materials than is typical with 5500Mpa tensile strength carbon fibres along with graphene fortified resins. Aerospace rated adhesives are also standard. This results in a stronger than factory repair.

What tools do you use?
OEM Raw carbon with custom gold leaf logos.
Will the repair affect resale?
A repair shouldn’t affect the value but people and the markets are irrational at times as we have all seen with the ridiculous prices we saw under the covid shortages. With a highly skilled repairer, the repair quality will typically exceed the quality of the rest of the frame. Quite often, many repairs I see are, in part, a result of a manufacturing defect. An acute impact event, such as a crash or transport damage, will occur over a manufacturing defect that contributes to the damage due to the weakness caused by said defect. You only need to turn to the Youtube engineers that cover the cycling industry to see examples of the manufacturing quality standards on carbon frames.
When you sell a frame it loses most of its value because the warranty services in most cases aren’t passed on to the buyer.
The truth is, your bike is worth exactly as much as someone is willing to pay for it. But a repair shouldn’t play any roll in that evaluation.
