I'm looking for a shop or someone in the Canmore/Calgary area that could do a repair on a Santa Cruz cracked chain stay. Not 100% broken but a serious crack, still straight though.

I wouldn't trust carbon thats been repaired, even professionally. Once those fibres are broken its pretty difficult to get them back to their original strength/integrity. You would be better off replacing the rear triangle

I'm an aircraft technician and I work with a few structural fitters... And the aircraft I work on is 90% composite materials

Carbon repair is totally safe if done by a professional. It will add a little bit of weight (less than 20 grams) but will be just as strong. My buddy does a lot of carbon repair on bikes and he's never seen a frame break in the same place. Carbon fiber repair is awesome. I've seen almost entire top tubes and bottom bracket areas fixed. Get that carbon repaired!

Well if people have had good experiences with it then I stand corrected

Quite a few comments on here about not trusting carbon repair.

Coming from someone that’s repaired several hundred frames and I haven’t had a single one come back For warranty I’d trust it. I buy broken frames now and repair them and then buy old it up for my personal bike.

I am biased since I run a carbon repair shop.

I have not repaired carbon, but generally if you contact the manufacturer, they may have shops they use/recommend for carbon repair. I know Ibis has a few shops they recommend in CA.
