Anyone make a 9 speed cassette with a 14 and an 18 teeth cog?

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?

Cheers

You can use something from a 10 speed cassette, at least I have added
a 32 tooth cog from a 9 speed cassette to a 10 speed cassette with no
problems.

Just from my experience, the cogs on 9 and 10 speed cassettes are
very close to the same thickness but the spacers between the cogs is
different so you need to use the correct spacers if you are using any
sort of indexed shifting.

Cassettes are made all in a set is for a purpose. The shifting lifts are aligned properly for shifting. If you mix and match be ready to get noisy shifting.

I think that both of the gears you're looking for are on the normal 11-23 Shimano cassettes. But the 18 tooth I attached to a 16 tooth on the Ultegra cassette.

Right now my corncob that I cobbled together and want to replace is 11 to 19 teeth and the shifting is fine even though one cog is from an 8 speed cassette. Sure is nice on the rolling hills. The front is a triple 48 -38 and iirc a 28 chainring. If it's not a 28 it's a 24 chainring. For some of the riding I do around here that setup is absolutely perfect.

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".

Update.

I just looked at the Sunrace website and see that they have CSR91 9AS which has 11-12-13-14-16-18-21-24-28 teeth. They also have CSR91 9AQ which has 11-12-13-15-17-19-21-23-25 teeth. With both of those I can build up my corncob 11-19 teeth cassette AND have it indexed! Great.

Cheers
