The Acor Frankie locknut is an oddity. It is supplied with Acor packaging but the locknut itself is branded FSA. FSA owners Tien Hsin Industries previously sold these as FSA SureLock – click to see more details. The only difference is that as an FSA product the locknut was stamped ‘FSA’ on one side and ‘SureLock’ on the other, while the Acor product is stamped with ‘FSA’ on both sides.
From our research, we can find no link between Tien Hsin Industries and Acor, other than the Taiwan connection. It seems logical that FSA were planning to drop the locknut due to limited demand from a shrinking threaded headset market. This is perhaps where a deal was struck with components giant Acor to keep the product alive.
The 6061-T6 alloy locknuts were supplied in the same 1″, 1 1/8″ and 1 1/4″ headset sizes, but only available in Black and Silver and without the allen key.
