I tend to keep my bikes for a few years… I've only owned two frames that I've not broken. The Nicolai Nucleon I just sold and the Nicolai Helius AM which I've only had for a year. There is one other frame I didn't break which is a Trek 8900 from 2002 but I wore it out - the threads in the bottom bracket seemed fine but bottom brackets always got loose in it even with PTFE tape or threadlock etc.
I'm on the lookout for a new hardtail… certain Ti frames are off my list :o)
