Need a different stem.
 

I'd like to put an Adjustable Stem on my Worksman custom cruiser and don't know what size to buy. The Wald #4 stem that comes with the Worksman measures .800 dia so which size adjustable stem will fit right?

I have a couple of Kalloy Adjustable stems on other bikes I own and wanted to transfer one of them to the Worksman but they measure .875 which is to big compared to the Wald stem now installed.

Any suggestions**********

Post 24 in that thread says a 21mm BMX stem works. Not sure if your fork is the same, or if there are adjustable BMX stems.

Noted and bookmarked the linked thread. The stem I have is 21.0 mm (.800) so I'll look in the bmx catagory. Thanks.

If I am calculating right, .875 is a 22.2mm stem. To fit a 21.0 tube you would need a .6mm shim. If you can not find one comercially available, you may be able to find .6mm shim stock and make your own.

I did this for a 26.8mm seat post I wanted to use in a 27.2mm frame. No .2mm shims available, so I bought some .2mm shim stock and made my own. Works fine.:thumb:

Thanks but :lol::lol::lol: Check your numbers, mate. What you suggest is backwards. :innocent::innocent:

I was figuring for a threadless stem, but from your response, I guess you are talking about a threaded stem?

If you have a fork steerer inside diameter of 0.833 " [or .020 larger than 13/16"]
It is is the smallest stem type.

A possible kludge , get a tube type quill stem raiser, they are a 2 stepped tube,
the smaller end goes in the fork,
and there is a quill wedge to tighten it into the fork..

the inside diameter of the upper portion, is the same as the outside diameter
of the lower part.

these are made to put the original stem into, and have it higher up,,
they are made in the common sizes
,833",.. (.874")7/8"-.22.2mm,.. 1"(9/8"od) current mtb size..
If you still want to fit an adjustable stem on, ...

a shim between the top OD of the tube riser you installed,
and the 28.6mm, 9/8" 1.125" that it needs to be
to clamp on a threadless stem of the adjustable type is possible..


wouldnt do tricks or aggressive riding with this combo,
But for JRA, it will do the job..

Quill stem ,mate, quill stem............

From what I'm finding there isn't jack aftermarket for 21.1 mm stems to choose from. Crap!

look at this thread. http://www.schwinnbike.com/forums/sh...ad.php?t=79845

How about getting a 22.2 threaded to threadless adapter and having a machine shop turn it down to 21.1 for you. Then you could put an adjustable stem on the adapter.

Might not be the way you want to go, but what about an adapter to convert to threadless? Adjustable threadless stems are available in different sizes also.

Nah, thanks. All I have to do is take an adjustable stem to a machine shop and have them turn it down 1.1mm to make it the correct 21.1 mm size that's my plan now. I may even take the extra 24.5 mm stem I have to the shop instead of tearing down one of my built up bikes to cannibalize a stem from it.

Sounds like a plan.:thumb:
