I picked this 1994 Bridgestone XO4 a couple of months ago. In the process of getting it taken apart the threads in the drive side crank arm stripped, finally today me and my neighbor were able to get it off. Now I can get it on the road. It seems like all the parts are here, just need to true the rear wheel get some tires and new cables to get it on the road. Need to replace the bottom bracket and crankset since it is junk now. It seems all the parts are lower end for the time so I might replace the crankset with something a bit more up on the scale. The original was a Shimano Atlus C-50 any suggestions of what to get instead?
