The on-one kit is out of stock. Other converter kits I have found suggest they are 8/9speed compatible only (A2Z/Gusset etc). I thought shimano 8/9/10 speed hubs were one and the same and only required cassette spacers?

Is the issue that the supplied cogs will be too wide for a 10speed chain?

Bump for the daytime crowd…

the converters will have been around before 10 speed was a thing, and none of the descriptions updated.

10 speed sprockets are the same width as 9, it’s just the width between outer plates which is narrower on 10 speed.

the kit you linked to will work with 8/9/10 speed hubs and any 3/32″ chain (8,9,10 or even 11 would work).

Cheers cp, as I thought. Thanks for the confirmation
