In the emantime I needed a new saddle and post. My LBS measured the stem internal diameter as
25.4mm (an inch in real money). However, his 25.4mm stems could not be gripped tightly enough. The
25.6mm stems were too big, and did not fit. So now I have a 25.4mm plus an old coke-can acting as
padding.

Does anyone know what standard sizes stems are?

Look at the seat posts listed on sjscycles.comvIndex.htmOpen ↗

Nothing between 25.4 & 25.6

I'm not sure there is a "standard" seat post diameter. My seatpost is
31.6mm while my brother's is 26.8mm. There are lots in between too, making it quite confusing.

Maybe find out from your LBS if a seat post shim will do the trick? Otherwise, they're available
online from places like Wiggle (if you know what you need).

If you're getting a new saddle by all means consider comfort and performance first. If you get one
with those "holes" (cutouts for anatomy) you could thread a cable through that to make it more
secure too. You can also buy non-QR seatpost clamps but all the thieves will need are a set of
allen keys.

I hate thieves! Can't understand how some people just don't have a conscience.

What a b*****d! A conventional bolt, if not security bolt thingy, would be better for next time
instead of qr. Good luck.

You might find a different brand 25.4 happens to fit better (or even a different 25.6 may fit)
because they're not all precisely what they're supposed to be. If not, the coke can shim again
should be ok.

27.2 is the most common size. 25.4 is unusual. They tend to go up in .2mm increments, in
even numbers.

I have a bike with a 25.4 seatpost - mine is a Kalloy. This size tends to indicate a bit of a "gas
piper" as the tubing is very thick!

My old, ancient Raleigh has some padding the same thickness of your coke can around the seatpost
stem. It's the original seatpost tho, so I think it was designed to be ill fitting.
