OMAS Big Sliding Alloy Headset Top Locknut: 1" Threaded (BSA) - 8g - Campagnolo Nuovo/Super Record Upgrade!
O.M.A.S. is famous for their Campagnolo Record / Super Record upgrade parts, nuts, and bolts. They produced these parts mainly from 1978 through the early 80's. This is from their flagship Big Sliding headset, and it is also used as a direct replacement for all Campagnolo models. The profile is almost identical to Nuovo Record, where the Super Record top nut is a touch taller for a higher stack height.
Excellent used shape. Some general marks, mostly on wrench flats.
