if you're gonna get the lager used might as well pick up a clockwork or sst off bikesdirect.
I wanted to build a kickback wheelset, but velocity dropped my order on rims so i kinda stopped caring. the frame isn't hi-ten, just the fork. guessing tro-moly is advertising jargon for straight gauge 4130 (like the lager). if you live on a hill i'd recommend getting a front brake to supplement the coaster brake.
