Oh yeah, this baby will definitely be going back on the road. The rear is spaced at 105 mm and the front is at 95 mm (hub search should be fun). I stuck a 26 x 1.95 front in there to use as a mock up. It was pretty snug, so I'm thinking that a 26 x 1.75 will be about right. The seatpost measures about 25.8 to 26.0 and the stem comes in at 22.0. Here's a couple more pics.
