The rules as laid down at the original Old School Race meets
1, All bikes to be pre 1990
2, All bikes to have 1" threaded headsets and caliper brakes
3, No New Skool bikes allowed
4, 20" or Cruiser can be ridden
The OSS Rules
Bikes must have 1" threaded head tube, caliper brakes (pitbull and center pull allowed) and 20" wheels. No Retro, Anniversary or replicas.
Riders of any age can compete.
I know the rules can exclude some bikes, but this is the Old school, not the Old school with a bit of mid school thrown in.
Thanks
