Will these 25.8mm fit onto a 1960's quill stem? I was under the, possible misapprehension, that I needed 25.4mm. I'm guessing they'll be fine.

With a difference of 0.4 mm i would imagine if you tweaked your quill stem open slightly it would be fine,could'nt be certain but with such a small difference i could'nt imagine it would be much of a prob.I would wait and see what others advise first though before taking my advice

Cheers Chris! I think!

I'm no expert but if your quil stem are like mine (two piece) I reckon you'd get away with an extra 0.4mm. Like Chris-H say's you better get better advice though before purchasing, good luck.

BTW, that link or any link to Planet X won't load for me since. Did it work for you?

Yeah, it worked fine for me

Link opens for me but says they are 26.0 mm ?

IME, although you might be able to open the jaws of a 25.4 quill stem far enough to stuff a 26 mm bar in there - it's pretty much a impossible to do so witout scratching the surface of the bar.... and those look shiny !

If you are shopping at PX I'd get one of their 26 mm quills to go with it- like this www.planet-x-bikes.co.uk/i/q/ST3TQUID/3ttt_quid_quill_stem

Cheers Pete. The page listing all their road stems says 25.8 but the actual product page says 26. Confusing.

That stem looks like a good bet at the price though so I'll do as you say.

 

[PpPete]

Well at least you'll have some to blame that way !

26mm is the standard.

 

[slowmotion]

Whatever you do, don't ever use PVC tape as a shim. It creeps over time, and it slips.

 

[PpPete]

26mm is the standard.

I disagree. 26 mm is one of those continental imported fashions. 1 inch (aka 25.4) is THE standard.
Me? start an argument ?

That's what Sheldon Brown says Pete, so you're in good company!

25.4mm Standard I.S.O. size, used on the vast majority of newer bicycles with upright handlebars.
This size was formerly common for steel drop bars

25.8mm Unofficial in-between size used by some Italian handlebar makers for handlebars designed to be usable in either ISO (25.4) or Italian (26.0) size stems.
SB suggests I'd be okay anyway but I'll do as Pete suggests at those prices.

Thanks all

25.4 seems to have been taken over by oversize bars now to my annoyance.
