I'm going to make an inner tube cover for my dropper seatpost.

I understand the sizing of MTB tubes, but I'm after a really thin diameter tube that will fit tight over the post.

Any ideas what the smallest diameter size is that I can easily get from my LBS?

Thanks,

    well you can get smaller than your seat post just get a suitable road one.

    or pop into your LBS with some cookies and ask them if you can get some binned tubes.

    Any road tube - they're generally 700x20-28

    I just used a standard 1.9-2.2" tube that I'd ripped the valve off to make a gaiter for my Joplin 4. 3 years on and it's still fine.
