Questions about Safety of Carbon Repair.
Moderator: robbosmans
Hi, there.
A few days ago, seatstay of my bike is partially cracked, because i installed my bike on indoor trainer with the wrong way.
really like this bike and can't get it anymore, so I'm going to use it with carbon repair.
I will consult a carbon repair company to get repair and partial painting.
Carbon repair companies claim that small areas of carbon damage can be repaired and used safely.
Of course, Buying a new carbon frame is most safe, but if that isn't the case, I would like to ask you 'carbon repair is safe'?

What are we seeing in the pic?
Of all frame materials, carbon is the easiest to repair, and the repaired area can be easily stronger than new.

Focus on the part that end of wooden stick.
when i press that part with wooden sticks
, it sink easily with 'spliting sound'.

Looks like we're looking at the inside of the drive side seat stay?
Also looks like something grinder it down through the cosmetic layer of carbon to the structural. So yea, definitely going to need to send it off for repair, but I'm going to agree that most reputable shops are going to send you back something as good as or better than original.
I'd also recommend getting a few estimates. When I cracked my frame I had one very reputable and well know shop shoot me back a quote like it's another day at the office. Another reputable but not as well known shop sent me back a similar quote and told me that he could fix it, but in his opinion I'd be better off putting it into a new bike (and didn't try to sell me one of his).

So far, it has received estimates from three different carbon repair shops.
They all said that the crack was repairable.
Shops all said the cracks were repairable, and since the crack is small, there are no safety problems after repair.
I have asked for repair to the shop which has most reliable ways to repair(shop that fixes carbon cracks the same way that the cracked FRP yacht is repaired).
If safety is proven after frame repair, I will be able to ride bicycle without worries.
Didn't you have any safety issues after the crack repairs?
It's very repairable. Just make sure they check for chain clearance in small cog when done. A very reputable company left a friend of mine with a Colnago where a 12 is unusable due to the thickness of a repair in that area. It was a difficult repair, but still...

I didn't have it repaired. I didn't want to be without my bike for what was looking like 3+ weeks so I ordered a new frame. Joke was on me as the new frame ended up taking a month to arrive anyway.

Are you saying that reputable company finally fixed up a colnago frame?glepore wrote: ↑Tue Feb 13, 2018 9:03 pmIt's very repairable.

My poor English is hard to understand the exact meaning you are trying to say.
If you have repaired and used the frame, did you have any problem with the frame after repair?
I have had two different carbon fiber frames repaired by Calfee. I am 100% satisfied with the repair. The repair carries a 10 year warranty and I have no concerns about the repair being unsafe.

It's all downhill from here, except for the uphills.

I had a frame repaired by Carbon Solutions (http://joescarbonrepair.com/) over a year ago. Cracked chainstay and seat stay -- perfect repair and no issues in the following 10k miles, ridden hard in anger and on the trainer.
