What if you buy a 20" frame, transfer all your stuff onto it, and
sell the 18" frame?
I'm barely 6' tall and my seat is raised about 4" out of my 20"
frame. I can't imagine how high your seat is.

| For the limited cost, I would go with a 145 or 150mm stem and give it a
try...Kalloy (made in Taiwan) runs only $15.99 in catalogs.
Another option is to change the handlebar with a smaller bend ie:
3 degrees versus 5 degrees.

| the *correct* answer is to get a bigger frame - one that fits you
since you seem to rule that out i would go for the longer stem
though i think you might want to do better than kalloy for a y22....

| Since he was unsure if it would work, I only suggested a cheap stem as
a low risk try.
20" frame sounds like quite a jump though...

I'm 6'2" with loooong arms ;they drag on the ground. Because of this
I've been though this crap a few times (its expensive). Keep in mind
pushing the saddle too far back on mountain bikes can negatively affect
handling.
Unless the measurement is way way out dont under estimate your bodies
ability to adapt. (You did'nt hear that from me, I take no
responsibilty whatsoever for anything I write or say, at time of this
writting I declare myself legally insane).
Whats the saddle nose to mid handle bar measurement?

re: .-1
Patrick,
Tell them how you've adapted so far.
(sorry, I couldn't resist).

2994.8 | | WMOIS::GIROUARD_C | | Fri Jul 21 1995 07:01 | 11 |
| the correct answer is not necessarily a bigger frame. you chose the
frame size because of persoanl preferences. many, many MTB'ers go
for the smaller frame.
there is also a gadget that attaches the seatpost (Tri-geek item) that
allows a great deal of saddle adjustment. i'd suggest a longer stem
as well. they get pretty long.
those two should solve the problem.
(love my Y22!)

2994.9 | extreme adujstments, sacrifise preformance | SALEM::SHAW | | Fri Jul 21 1995 08:18 | 14 |
|
In either case, extreme adjustment will definately have negative
effect on any serious climbs and downhills. Seat too far back on a
climb will lift the front wheel up, a stem too far forward on the
front wheel will make you dive over especialy when you break.
I assume for one that spends the $$ for a Y22, preformance and
handling should be the number one factor and they plan on riding
more than just fire trails. I would sacrifice a little discomfort
in favor of preformance. I guess the most pressure will be transferred
to your shoulders and hands (ie, numb hands on long rides) It amazes
me that Trek doesn't have a frame size between 18" 20".
I actualy prefer it to be more like 17" , 19" etc...

2994.10 | Titanium seatpost? | ICS::swb01.pko.dec.com::Cleland | GPS eastern helpdesk | Fri Jul 21 1995 10:30 | 7 |
| How about checking out note 2.1082?
Justin is always selling good stuff cheap.
I'm still riding on a pair of his wheels I bought 4 years ago.
But the post is probably the wrong diameter and/or length...

I don't think he wants to move his seat 2" forward, though. 8^)

Thanks for all the suggestions.
I did some careful measuring this morning and found that
the distance from the back of the seat tube to the center
of the handlebar is identical to my road bike which is a
59cm frame. Also the stem length is the same but the
road bike has a negative degree rise so it is parallel
to the ground.
re: .9 I measured the distance from center of bottom bracket to
top of seat tube and found it to actually be 19" not the 18"
they state in the spec. Hmmm?
Performance and full suspension was definitely what I wanted
when I chose this bike. The smaller frame was to shave weight and
increase quickness in handling. All of this has been
accomplished.
I think I'll start with getting a 0 degree rise or a -10
(to make the stem parallel to the ground) and see how that
feels.
The bike is still fairly new and I may need more time to get used
to it and adjust my riding style accordingly.
Thanks for all the input.
See you on the trails.

2994.13 | Steel is Real | BOOKIE::J_CROCKER | | Fri Jul 21 1995 13:51 | 29 |
| I would suggest a steel stem with a 5 degree rise, 150mm or longer.
Steel is the wisest option when you get this long, because when
aluminum fatigues, it breaks without warning. Two of the big aluminum
stem makers, Syncros and Control Tech, both had major recalls last year
(neither will say exactly what the reason was, other than "catastrophic
failure").
Salsa makes a very good stem in this design, and they back it up
(they'll even refinish an old stem for $17.50, shipping included).
Colorado Cyclist carries Salsa ($50, if I recall). The Ritchey
Forcelite is also a good bet ($32.50 from Excel), and they make a 160.
I wouldn't be too worried about using a long stem if you get a safe
one that's been on the market long enough so you're not being used as
a guinea pig. Your seat is so far back, your weight distribution
should still be balanced.
You'll also find by doing a little geometry that using a lower rise
(like 5 degrees instead of 15) will give you greater extension.
Moving your seat back further is probably not the solution, unless you
have extremely long femurs. Seat postion is a function of your lower
body, not your upper. If you try to use your seat to compensate for an
upper body measurement, you will eventually screw up your pedalling style
(like spending a lot of time on the nose of your saddle).

2994.14 | exit | BOOKIE::J_CROCKER | | Fri Jul 21 1995 15:46 | 28 |
| There are two methods of measuring a seat tube: center of the bottom
bracket to top of the seat tube (c-t) and center of the bottom
bracket to the center of the joint between the seat tube and the top
tube. I believe you'll find that Trek uses c-c for its advertised
size (18"), so it follows that your c-t measurement is 19".
I would caution against going from a 15 degree rise to a -10, because
that'll lower your bars by roughly 2". If you feel that you're too
upright as well as scrunched up, fine. Otherwise a radical drop like
this 1) rearranges your body geometry, pulling you forward so you'll be
riding on the nose of your saddle 2) may put an unnecessary strain on
neck and back muscles.
You'll also find that your options for a -10 stem are pretty limited,
unless you go with a road stem, and most roads are 26.0 bar diameter
(or 26.4 for Cinelli), while the MTB bar diameter is 25.4.
If you want only to increase extension, the best way to do it without
messing up something else is to increase extension -- get a longer stem.
I would also suggest that you give Trek a call. They put a significant
amount of time not just into frame design, but also into frame
build-up. They can probably give you some useful input on how to go.
It'll help to have your bike right by the phone, with a tape measure
and possibly a plumb to drop from the nose of your saddle (in case they
want a measurement for how far behind the bottom bracket your saddle is).

2994.15 | Just turned the stem over | NODEX::CLBMUD::mcgreal | Pat McGreal 297-2285 | Mon Jul 24 1995 14:11 | 10 |
|
After speaking with the bike shop they suggested simply turning the stemm
over. This makes the stem almost parallel to the ground and does produce a
bit more extension. The strength of the stem is not compromised in any way
by doing this.
I can honestly say that my position on the bike does feel somewhat better.

2994.16 | .15 for AheadSet Only | BOOKIE::J_CROCKER | | Mon Jul 24 1995 15:18 | 7 |
| .15 only works with AheadSet style stems (in case someone with a
traditional stem is scratching their head and wondering how you turn
over a stem.

lower body, not your upper", try: "How far forward or backward your
seat is is as much a function of your lower body as it is your upper."

Yup. Good point.
Forgot to mention this only works for "Ahead set" style steering.
