Just about finished my daughters Pompetamine but I still need a rear cog (I’m going SS for her to keep it simple and light and she doesn’t really do any hills).
Its been suggested that a 42:20 or 42:22 setup would be good to start with but I’d like to try one or the other out first before I buy a nice cog just to make sure.
Anybody got one or the other to fit Shimano cassette they could spare so she could give it a try? Happy to pay postage, etc.

I think I might but need to check my spares bin tonight.

Cheers 🙂

sorry dude but its a no, biggest i have is an 18t

sure i have a new 20t you can have. pp gift to email addy in profile £3 and its yours.

HI DMP. Just trying an 18t on the bike to see how daughter gets on. What make of ring is it (wide or thin base)?

oh its just a thin base no name one….

Have you not got a cassette you could throw on and an 8/9 speed chain, just for trying before buying?
That’s how my newly singlespeeded roadbike is being run.

I looked for an old cassette but I’ve actually tidied/thrown them away.
Anyway, went out for a quick spin with daughter #1 earlier and she says the 18t cog (£2.99 from CR) is fine so I may stick with that, but a 20 would be handy for more hilly stuff. She’s got a, 42 up front btw.
