What Stem Will I Need?

Postby albo » Sat Sep 29, 2007 19:20 pm

Hi I'm Albo,
I'm quite new to all this so sorry if i do something wrong or annoying :) although this is probably annoying you :oops: sorry

> well, a few days ago i bought some brand-x handlebars http://www.chainreactioncycles.com/Mode ... odelID=230 for my "mongoose tyax" and being the idiot that i am forgot to check sizes etc., so the handlebar diameter is too small for the original mongoose stem, does anyone have any help on which new stem i should get to accommodate my handlebar.

Any help would be much, much appreciated. Thank you :D

Any with a 31.8mm bar clamp. Plenty to be had.

However it does say that the bars have a shim, which you should be able to remove and use with your existing bars.

But will i not need to check steerer tube diameter to know the new stem will fit with both steerer tube and handlebars?

99% of stems are 1+1/8th inch - though do check.

err wrong.

Heavy duty DH riser bar. With a 4mm thick wall, these bars will withstand alot of abuse. 22.2 mm diameter with a 25.4 mm shim. Extruded 6061 alloy, shot peened around the stem area to increase fatigue life. Suitable for DH and freeride.


ypur current stem is 31.8mm at the bar end.

you either need a new stem that is either 22.2mm or 25.4mm


or have a look for a 22.2mm to 31.8mm shim.

don't get a new stem!
Send the handlbars you've got BACK to chainreaction (they're fine with refunds)
and instead order some oversize handlebars. e.g.
http://www.chainreactioncycles.com/Mode ... elID=16530
OR
http://www.chainreactioncycles.com/Mode ... delID=3456

That way you don't downgrade from oversize bars to standard, and you don't spend any more money.
