    Would it not make sense to use a shim like this one?

    I’ve used a USE shim in a 31.6 frame for ages with my 30.9 Reverb, no issue whatsoever and a bit cheaper than the alternative. Plus if you ever go back to a 30.9 frame you’re sorted.

    A lot of frames advise against shims and some even invalidate the warranty.

    Plus a 30.9 – 31.6 must be tissue paper thin isn’t it?

    New frame on the way that’s 31.6 seatpost and my current frame is 30.9.

    I have a Reverb but rather than buying a new one, I’m sure I read on here the other week. That all you need to buy is a new outer seat post sleeve in 31.6 and you can swap them over and change the size to 31.6. Cost about £35.

    Is this right? Anybody done it? Instructions?

    Presumably they use the same collar at the top? Or any other parts needed?

    Hope somebody can help.

    It’s about 0.7mm thin/thick 😉 Edit – no it’s not, i’m a tard! ).35mm 😳
    The USE shims are a decent length so I’m not worried about putting stress on the frame, I know plenty of people that do it.

    No problems here using a 30.9->31.6 USE shim. They’re fairly long (100mm?) but you probably would want to check whether the frame manufacturer indicates a minimum shim length

    After a monster thread here a while back just double check the warranty situation with a shim. If the outer sleeve can be replaced for £35 that would be the option I would take

    Or see if you can find someone in the opposite situation and do a swap?

    USE shim here too Rik, no issues.

    I’ve got a 2012 31.6 Reverb, and I now need a 30.9.
    It’s 125mm drop 380mm post, left hand lever.

    Happy to discuss a swap.

    Cheers
