Hi,

What was the standard diameter pre 31.8, can anyone remind me please?

Also, does anyone have a 50/60mm old standard stem that they’ve move on from and want to move on for much cheapness?

Thanks.

Stu.

25.4mm

Thanks.

As above. Exactly 1″ The part the grips and controls go on is 7/8″

Yuo can get shims to take your 25.4 bars upto a 31.8 aswell. They come supplied with the Guessett Staff stem, but you’ll be able to buy em separate.

You can get stem shims if, as I think, you’re trying to use a 25.4mm bar.

I’ve used them without incident. On my SS for about 5 years now. Easton actually make/made some.

These used to be much cheaper, i’m still using mine but i remember it was something like £6, now it’s £19!

I think the classifieds will be your friend here, loads of people will have this stuff lying around not being used as it’s uncool. 😀
