Hi everyone, first post so take it easy on me.
I just picked up a Suntour Superbe 2100 rear deraileur to swap out for a Shimano Deore XT someone put on my '82 Miyata 310. After aquiring the deraileur, I read its max cog is 23 tooth. Is there any way to make it work reliably or just sell it off to get something else? Thanks in advance for your time.
