Vintage Components - Shimano MF-Z012 & UG Freewheels

On this page:
5-speed MF Z012:
14-32
6-speed MF-Z012:
13-24 | 13-26
6-speed UG: 14-34

Despite their industrial-sounding name, MF-Z012 were well-made freewheels, equipped with cogs made for freewheels higher up the Shimano line. They are index freewheels.
