TREK Domane SLR7 2021 frame crack

[The_Kruiser]

Is that a 7 grand bike ? I'd be fairly sure I'd get decent service from the company after spending that much cash on a bike.

It's for 9k.
They agreed to replace the frame

We need to know the answers to this, really. If it wasn't second hand 2 months ago the that is some pretty rough treatment of a new bike imho.
If it was, I would be going back to the seller.

Bought it new from the showroom.
After looking into all the records , TREK has agreed to replace the frame & its on the way.

 

[The_Kruiser]

Excellent customer service by TREK & their dealer.
Super efficient to look into the details & get back with an answer real quick.

Blimey. Glad they are sorting you out.
A mates s works cracked whilst flying and after that was replaced we found a hole in the fork in the middle of a ride. They replaced that too.

I wonder if the high value carbon isn't as resilient to knocks as the cheaper heavier CF ?

CF can be repaired fairly easily though.

Sure replace the continuous fibers running whole length of chainstay, easy-peasy.
Slopping some resin on it, even with fibers added would crack on first hill climb or pothole

Are you sure about that ?

It's a bit more involved than that, but there are companies which offer a repair service.

pretty sure, assuming it was manufacturing defect and it's fatigue crack:
You would have to sand down the paint, inspect for lengthway cracks(x-ray wouldn't hurt) wrap the chain stay at least 2 inches each side of the crack with carbon tissue and vacuum bag it to have any confidence in it, not an easy repair, that's for sure.

I didn't say it was a DIY job but it's bread and butter to the many cf repair places.

I've had a Cervelo R5 repaired a few years ago that had a similar crack to that. (Heathrow baggage handler crush, no brace between stays, one broken seat stay and one broken chain stay). Repair cost ~£200 (not much paintwork to remedy). Bike heavily used since, literally thousands of miles. No issues at all.

Of all the frame materials currently being used, carbon fibre is the easiest and cheapest to repair.

A fatigue crack after two months?

A fatigue crack after two months?

Air bubble could do that.

 

[Mr Celine]

Air bubble could do that.

Air bubbles don't crack.

That "2 month old" bike looks worse than my 10 year old steed

Sorry to see this, yeah there’s warranty but you will be waiting until after Christmas.
