Sorta a 29er...cross combo...originally, that Fuji frame was a hybrid with 700x28 tires. I put a VooDoo 29er fork on it with a 29er tire... the rear tire is a 700x37..knobby... wheels are bolt on from a fixie I had. The rear hub was flip-flop so I was able to use a freewheel on it with a DMR chain tensioner. .. only thing left that's original is really just the frame. Rear stays won't fit a 29er so I went as large as I could with cross tire....just enough clearance to make it happen. ..turns out, it's a really nimble and fun bike to ride
