Sir Ridesalot said:Steve Sr. said:MTB gurus,
I have a 1992 vintage Trek 950 MTB and would like to raise the stem to
improve the fit (too much weight on hands). This bike is ridden
mostly on dirt roads and rail trails. I do very little single track.
The existing stem is adjusted all the way up to the maximum line. The
current stem appears to be a 1" quill. The headset is marked Tioga -
Avenger - Japan if that helps any. The bar diameter appears to be 1"
as well.
The first issue is whether or not 1" quill MTB stems are still
available.
The second issue is that the cable for the front brake goes through
and uses the stem for the cable stop. Somebody should get an award for
that one! So even if I find a longer stem if it doesn't have a brake
cable hole I will need some kind of bracket to hold the end of the
brake cable. I have seen these before on older bikes but have no idea
where to look for just the bracket and for one that would fit under
the headset nut.
Can any of you offer any hints or suggestions or are these parts all
long since obsolete?
Thanks,
Steve
Hi there Steve.
Some others have also mentioned the adjustable quill stems.
Here is a link to my converted mtb with the adjustable stem and drop
bars so you can see what that stem looks like.

In the picture the stem is almost 90 degrees from the quill. I can be
rotated up and back so that it is almost vertical. So you have an idea
of how much height can be gained. What is great with the adjustable
stem i s that you can raise or lower the bars to suit the conditions
of the road you are riding. For example On rough dirt or fire roads
where you might want a more upright position for visibility you can
raise the stem. Then if you want to ride fast on paved roads later you
can lower the stem again.
That is the Radical adjustable stem and it sells for about $25
Canadian.

Peter,
Thanks for the picture of your converted Miele. It looks like you have
long arms to have the bars that much lower than the saddle.
Unfortunately I have just the opposite problem - short arms. I need to
have the bars about even with or a little higher than the saddle.
To continue the saga I stopped by my local LBS yesterday to look
through the catalogs. We started with QBP then Hawley and finally BTS?
Apparently due to the way quill stems are measured (O.D of the steerer
tube that you can't see and not the quill diameter itself) what I
really have is a 1 1/8" quill stem.
I did some measuring of the current stem and it measures as follows.
The height at the minimum insertion depth is 100mm to the top of the
quill bolt. The stem reach is 115mm at an angle of 120 degrees from
the axis of the stem (30 degrees rise from perpendicular to the stem).
With the new setup I would like to increase the max bar height to
about 25-40mm higher than it is now. In looking through all of the
catalogs there were few quill stems that were long and none were 1
1/8". Apparently 1 1/8" quill is a red-headed step child that didn't
last long before threadless emerged.
Can anyone else offer any other places to look for a long 1 1/8 "
quill stem?
If I can't find a stem I guess I will have to look at a long 1 1/8"
quill to 1 1/8" threadless adapter. Have any of you seen these that
would be tall enough to fit the above requirements? Unfortunately, I
didn't have time to look at these when I was at the store.
Thanks,
Steve
