GIANT TCR SEATSTAY FRACTURE

The only reason I am showing this 1 example of the many seat/ chain stay repairs I do every day is that occasionally I will have a go at re-enstating the graphics. It’s good practice for me and the bike looks better for it.

FONDRIEST SEAT POST REPAIR

A poor design from a great bike company. The seat post bolt hole was far to big with not enough shoulder to stop a potential pull-through. I had to bore out what was left and re-build the area with my special CF/Colloidal paste. Job done. Happy customer.

CUSTOM VITUS 992 10 speed

Occasionally I will turn my hand to other materials such as aluminium and leather…OK there is some carbon in there as well. I looked like a blacksmith at the end but absolutely worth it!

CBR GOES INSIDE!

We can now go right inside the frame with a video scope! This will save on a lot of un-necessary cutting away of good carbon, something I hate seeing in CF repairs. More importantly we should be able to find the exact source of the fractures to ensure we get them all.

This month has been epic with all sorts of summer ‘breaks’ and de-laminations. Thanks again for trusting CBR with your precious bikes!

ARGON 18 MULTI FRACTURES

This poor TT bike came 2nd best to the tarmac. Especially the down tube, end bar and Zipp disc. The down tube fracture was extensive and took some work to re-build and profile but it came out perfectly in the end and saved on a replacement frame now out of warranty.

ZIPP 808 DISK PUNCTURE

As part of a larger bike repair this rear 808 disk needed to be repaired to ensure no de-lamination would occur at high speeds. The Zipp texture is interesting, at first I thought it was a fabric coat over the CF but it turns out that it’s only a mold texture. I think it adds additional structural stability across the surface and golf ball air resistance maybe? Anyway I applied a patch and profiled it as close as possible without damaging the surrounding surface.

COSMIC CARBONE SLR CRACKED RIM

This front wheel hit a pot hole and the customer was hoping this could be repaired considering the cost of such a tub. With a profiler to ensure the repair set true he now has his beloved wheel back and ready for a trip up the Alps before summer is out

CANNONDALE SIX SHEARED FRONT END

When a large frame for a specific size rider is damaged, the rider has few places to turn. This frame was structurally compromised when both top and down tube separated at the head tube. A fairly time consuming repair but worth it in the end. This one I also sprayed

FELT DA CRACKED SEAT CLAMP

Apparently this is an issue on this model. It’s a tricky repair because you can’t remove the bonded half that is cracked so the next best thing was to wrap it in a carbon blanket to bind it together. I don’t like this design because of the amount of flex under a moderate torque. We had to get this out fast for a race this week. Good luck Jack!

IS CARBON REPAIR WORTH THE COST?

Of course! If anyone wants a quality carbon frame but can’t afford a new one or indeed a 2nd hand one without damage (….) then the next best thing is to Ebay a damaged one of the right size.

Do the math. Recent example :

Felt F6 frame (14 months old) cracked seat stay – £155. New £800/900?

Half wrap repair (one side) £150. Good as new. Total – £350
