I just got lucky with this one. The guy did not mention brand or model in his add, for him it was just an old hybrid. People have already found out the old Multitracks have nice steel and take 42mm tires so everyone is doing gravel conversions.
Specialized Crossroads also fetch crazy prices, even if they always had modest components and frames.
To be honest, I've put mine for sale locally. Don't want to sell it, but if someone is willing to pay, it's not that I'm short on bikes... I'll keep riding it on the meantime.
I do it with most of my bikes, put a price I would not mind giving the bike away, while I keep enjoying it.
