I picked up a GT ZUM frame from Nashbar for super cheap and thought of building it as a urban fun bike.
Any idea what headset it takes? Tire clearance? will a 2.1 maxxis hookworm fit out back?
fork A2C size? I have a surly instigator I can put on.
thanks for any help. I searched a bit but not much info on this frame.
