I need a 9-speed 14 teeth and a 9-speed 18 teeth cog for something I'm doing. Does anyone make a 9-speed cassette with one or the other of these cogs or even both of them?

I have OLD Campagnolo 9 speed cassettes in 13-23. They are 13-14-15-16-17-18-19-21-23 cogs.

According to this website, there are Shimano 9 speed Junior cassettes in 14-25 and 16-24 configurations. Both have 14 and 18 cogs.

Do a Google search on "shimano 9 speed junior cassette".

Thank you VERY much for that advice and link.
