Only if you don't consider death or serious injury to be "major problems" ๐Ÿ™„

You CAN do it.

You probably SHOULDN'T do it! I wouldn't.

You can try a [url= http://www.chainreactioncycles.com/Models.aspx?PartnerID=79&ModelID=25136 ]shim[/url] , using an old inner tube may not be the best idea..

YES you can if its an Easton Bar & stem - they make a shim to suit, works a treat!

otherwise it a no go.

31.8 - 25.4 = 6.4mm

That's a big gap to be taking up with a shim. Especially a rubber one!

Yes, but for pity's sake use a proper shim instead of four thicknesses of inner tube to twang around inside. Easton do them, and so do others.

Jones H bars come with a shim for 25.4 to 31.8 - not had a problem, never heard of anyone having a problem. So, yes, you can do it.

A proper shim is fine. There's plenty available, even Thomson make one. A bit of inner tube is certain death...

I have been sensible and made up a proper shim. 1" of old seatpost and cut in half. that would be fine?

Yes it can be done. I used an Easton shim in a Thomson stem to hold Race Face bars! Simple.

Yes, but what about a 31.8 bar in a 25.4 stem? I can just sand a bit off the outside off the bar and a bit off the inside of the stem can't I?
