I love old, used parts and trying to find out their history.
Old set of Drag Specialties Holy Pegs. These were a knock off of Randy Smith's Custom Cycle Engineering Holy Pegs and are cast steel instead of aluminum. I checked the D.S. catalog and they are no longer available.
They are threaded for a fine thread 3/8" bolt.
The original C.C.E. Holy Pegs are almost impossible to find and are priced accordingly.
