I have one, I like it (got it 6 months ago). I just rode it 80miles with 11,000ft of climbing and made it home without an issue. Maybe someone can tell me what to look at to determine whether its a hunk of junk or not. But I probably wouldn't be able to make a credible determination being that I am a "n00b."

My humble observations, I'll be the first to admit I don't know a lot so below is information from just a regular guy;
My dropouts were straight, no fancy axel nuts but meh to me (I don't expect my things to stay perfect for forever), the pedals were tight at first but they loosened up. My seat tube came slightly dented, but I fixed it, probably due to shipping by USPS from AZ to Japan. Front tire bead just separated from the casing last week, chainring bolts needed to be tightened to stop a popping noise. Pedals have a little little bit of play, possibly from trying to do too much climbing with 75gi? I, for some reason, get caught up with roadie friends going into mountain areas... Wheels seem pretty true still. Chain is stretched, just checked it today.

So far I've rode at least 1,049 miles and gained 45,056ft (according to Strava). So is a stretched chain, ruined tire and slight play in the pedals acceptable for the afore mentioned milage?
