I just pieced together a new single speed.
I used an old XTR crank with a Hershey retro-disk to hold a 32t front ring, with another 32t ground down to be used as a spacer for the bolts.
The rear hub has a 16t with plenty of spacers.
Sorry about the bad picture I took them with my phone.
ps major props to John on his 11:22:32 at Leadville!
