Old school stem size? can you get 20mm as well as 22.2?

(1/4) > >>

ED209:
Well.... I always thought there was only one size of stem but the SR Stem that shows 22.2 on the shaft will NO WAY GO into this Aero frame that I've got.

Can anyone fill me in on what size different stems can be???

* UPDATED *

I've just compared the sh*t stem that came out of the bike to my SR and its deffo smaller... probably 2mm smaller. Can you get 20mm stems? I should have guessed there would be a problem as the bearing race that goes on the forks was too big and I had to file the sleeve at the bottom of the forks down to make it fit. The headset fitted ok ( as it would with the same threads on a smaller tube ) but the stem is a no go... unless I can get a smaller one.

* 2nd update *

I cleaned up the sh*t stem a bit and it says 21.1mm as the width.

May help if you remove your hampton from the fork hole 1st!!! ;)


No idea mate, thought they were all the same.

brummie:
old bmx are 22.2 as far as i know ed
any signs that the shaft has been rechromed? this can mate the shaft too thick and then no fitty fitty

nope - just a standard SR stem? not re-chromed.
