Carbon Frame Life expectency

[Li Mu Bai]

I have a U16 friend that rides a 2008 Felt F1 - review here:

His FTP is around 290 W but when he starts sprinting flat-out, the frame flexes so much that his rear wheel rubs against the chainstays.  There are two grooves in the frame already.

 

American Classic carbon wheels. 23 mm tubby.

The wheels also flex, and might be the actual problem, not the frame

Thanks verybody. Had my carbon Ralleigh (that I got second hand) for a very long time (I guess from about 2009).  I estimate I have done myself about 40 000 km (16000 just in the last three years here in Germany).  I just wondered if the frame will last carrying my 85 kg ass.  There might be an tax incentive comming that envolves bying a new bike.
