Im sure some of you guys have a back up bike. I just picked up a bike so I dsont have to ride my DK all the tiem and worry about it getting stolen. I picked up an early 90s Dyno Zone. Paid $20, and the thing is in near mint condition. What Im looking for now is, a decent cheap 3-pc crank, and a set of 3/8 axle sealed racing rims any recomendations?
