Hi
I have been having a hell of a time finding a 30.4 seatpost so I've been looking at these shims from USE. If I want to use a 27.2mm seatpost in my frame which takes a 30.4mm seatpost, am I correct that I'd have to buy the following: https://www.sjscycles.co.uk/seat-posts/ ... 272-mm-id/ and choose 30.4 as the outer diameter?
Also, I have my seatpost in quite deep and I was wondering if I should be worried about frame stress from using a shim? I am a 290-300lbs rider so I like things to be snug with no play at all. From what I can tell the shim goes down about 10cm, if my seatpost were to go further than that wouldn't it cause some kind of play?
