The wheels on my Steamroller are Velocity Dyads, DB Wheelsmith, and Dia Compe Gran Compe hubs. They're pretty much bombproof although they're a little wide for 23's. I run 32c Vittoria Randonneurs(not the cross version). Best tires out there IMO. As for my crank - it's a 175 Sugino 75 bolted to a 110.5 ISO Phil bottom bracket with an old school Sugino Mighty Competition chainring. I have never hit my feet on the chainstays but I only wear 11's which, apparently, are very small.
Just my .02.
What is your budget for the parts? It's kinda tough to made recommendations without knowing how much you're willing to spend(but i will anyway)!For wheels you can't go wrong with Velocity Fusions and Formula or Surly hubs. Spend the extra dough to have them handbuilt - you won't regret it.Check out http://wheelandsprocket.com/index.cfm
. And for the crank, I think Andels are a damn good buy right now. Everyone has 'em - Ben's,IRO,Soma, etc. Any bb will do ya but if you want piece of mind(and a lighter wallet) then get a Phil or White Ind.
