This is the person who more or less got me into the sport, which I'm thankful for, but today he told me he has 'no interest whatsoever' in riding a bike again. I find it funny since he recently upgraded his Trek 1500 to full ultegra and just bought his wife a Trek Pilot 2.1. So after investing 5k within the last year of cycling he calls it quits.

I'm not really hating on the guy too much I just find it interesting how someone can be totally interested in a sport and then just lose interest overnight. His new passion is running, which to me is like saying, 'I dont like thin blondes anymore, I like 300 lb brunettes now.' Running doesn't compare to cycling imo.

If his bikes fit me or my spouse, I'd buy them from him

It isn't really going to affect me, still its depressing having a riding partner just up and quit like that.
