Hey, thanks for lookin' out for me! A few years back (read: before my single speed obsession) I was seriously shopping around for that bike. Never found the right one though. Talk about a tank! Looks to be a good example.
Who said that thing is positron?!?!? DUH! That's just a regular one-piece crank up front.
I don't blame you for wanting to make it yours. That thing'll roll over anything!
Good luck with that.
