well, based on details provided, i'd say SHIMANO!
but if you'd like more specifics of what I've actually done, for my SURLY frameset i got last year:
https://www.bikeforums.net/23167417-post15.html
brakes: TEKTRO long reach R559 calipers - got them 'cause i'm planning 650b wheels this year
wheels: Paul Hubs and Velocity A23 rims. Dyads would be good too.
chain: i'm not picky. there's a whole sram vs Izumi going. read that.
pedals: Crank Bros egg beaters. -- Crank Bros are pretty affordable. I've only had on pair break on me, a pair of platform stamps. Probably lots better pedals out there.
if you want cheap wheels, maybe something with Origin8 hubs, but I'll probably not go o8 again.
