Hello,
I have gearing I really like on my Sachs 7-speed. The middle cog is worn, and I suspect the other two on either side of it are next. So:
Wanted To Buy three Sachs cogs, 17T, 20T, 24T.
Sachs ARIS 4th/5th positions 20T and 24T. These are called RY-20 and RY-24.
Sachs ARIS 3rd position 17T, this is called an FY-17.
Let me know if you have one new or good used.
