Not sure where you are getting this info from, they may be good guys and have lots of experience and know how, but they are thoroughly incompetent at fixing and refinishing carbon fiber frames. I know from very personal experience.

It’s been well documented on here by me and others:

Read through this and you will understand more.

I had a riding companion send a Colnago to Ruckus last year for a dropout replacement. It came back with some much excess on the inside chainstay. you couldnt use the smallest cog.

I fixed that, but...

Predator Cycling has a DIY carbon repair kit, I haven't used it, but its on my radar for use under the right circumstances. I'm sure there are similar kits out there from other companies as well.

I have personally used Henkel EA 9396, not for a bike application, but I can vouch for it. Its not cheap but it is strong.

Are you just going to patch it with woven? Is the crack on the length of the chainstay or the width? If its on the width there is a break in the fibers and while a patch will help it wont be as strong.

i do not buy into the internet alarmists who tell everyone that you have to get a "professional" to repair anything.

I just got finished using the cheapest Amazon kit to repair a crack in the down tube of my Carbon Trek Fuel.

Sanded a huge chunk out to ensure I got all of the damaged material and then put 4 layers of carbon fiber cloth of increasing size over the crack a layer at a time. I let it cure 24 hours or so between layers but that’s probably overkill. I was truly amazed how easy it was to repair so little cost.

Yeah, add me in for another Ruckus-absolutely-never-recommendation. Totally amateur-show at best. PM for further info if you would like.

Then you need to apply several layers, starting with a small patch and then extending the next layer another cm on each side, etc. Otherwise you create a stress riser and it will crack at the transition from the patch to the original chainstay. This won't be pretty, but it will probably work.

Definitely. As long as you scarf out each layer as muz said you should be fine. Just replace each layer that you remove and you'll be back close to new.

Hern Montenegro (MMFG) is on the East Side of LA. He used to work for Predator. Just did some shoes for KISS (seriously)
Makes a decent whip too.

One of my friends use GorillaCarbons a lot and highly recommends it.

I know what they mean by this in the product description but gotta laugh out of it. I always look for this when picking how to fix my bike:
“This kit was carefully created for lowest odor possible.”
