What is your question? The Technomic stems are probably the best for use with
Scott bars. I recently put one on one of my bikes with Scott bars and I
actually had to chop about an inch off of the bottom to get it down far enough
(about 1/2 in below my seat height). Its a good quality stem. I had to
spread the clamp just a little bit to get the Scott's in. I've also used
cheaper Sakae stems, but these needed to be reamed out a bit to fit.
ATB stems are also recommended for this purpose, tho they all seem to have a
long reach, and I need a very short reach stem (my Technomic is 50mm)

I'm using a Sakae AH stem with Scott bars. Essentially the
same geometry as the Technomic (230mm long, 60mm extension),
half the price ($10.90 in Nashbar), and I had no problems
installing it (no reaming, no spreading).

| 1063.4 | Why do all the pro's opt for Long Stems? | GSFSWS::JSMITH | Chromed Cannondale | Fri Aug 24 1990 12:40 | 13 |

I recently went thru an old cycling calendar and picked
up a peculiar point. It seems that the majority of the
pros (Greg included) have stem lengths that appear from the
photos to be in excess of 150 mm (old style, not TT, Aero
or Clip On's). One can only assume that this allows you to
stretch out more and thus lower your wind resistance, but
I can't imagine riding in a tight pack with such a twitchy
front end created by all that extension on the bars. Is
this just the trade off you pay for increased speed/performance
or are there some obvious benefits to having a long stem
(lets keep this topic non-sexual) that I am unaware of?

| 1063.5 | Stem only affects handling a little | SVCRUS::CRANE | | Fri Aug 24 1990 13:33 | 12 |

The length of the stem does not really impact the handling of
the bike that much. The angles of the frame, the wheelbase and
the amount of fork rake all combine to give a bike its handling
charactaristics. Most bikes used by the Pro are more layed back
slower handling bikes. Stability is more important to a road bike
than super fast handling unless you ride Crits for a living.
It is also more comfortable to achieve a low aero position by
stretching forward than to scrunch down into lower deep drops.

| For someone who has a long torso, it helps get their back flatter.

| 1063.7 | The basic equation they use | CIMNET::MJOHNSON | Matt Johnson, DTN 291-7856 | Mon Aug 27 1990 16:29 | 5 |
|
Longer stem =>
Shorter top tube =>
Tighter triangle =>
More responsive frame
|
| 1063.8 | Two more reasons | CIMNET::MJOHNSON | Matt Johnson, DTN 291-7856 | Mon Aug 27 1990 16:33 | 10 |
| o Wider range of hand positions. Many riders like to have two
hands close together on the bars, on either side of the stem.
The longer stem makes this seem more natural, and less "crowded".
o Weight is placed proportionally further forward, relative to
the wheels. Especially for bikes with laid back seat tubes
(the classic road bike style), this is important to prevent
"whippy" handling on descents.

| 1063.9 | less twitch, less filling | SHALOT::ELLIS | John Lee Ellis - assembly required | Mon Aug 27 1990 16:36 | 7 |

By the way, yes, the affect on steering might in fact be very
little, but the effect of a longer stem would be *less* twitchy,
more stable steering (because you would be steering at a greater
radius from the axis of rotation).
