| For me it would be rather pointless having a 32 sprock. My small ring
is a 24 and my largest sproket is a 28 which gives a 22 inch gear, thus
each revolution of the crank moves the bike 70 inches. If I required
anything less than that, it would be much easier and quicker to get off
and walk.

I could make a couple of guesses:
1) The pros are in better shape (or run smaller chain rings on the
front) so they don't need anything larger than a 28 on the rear.
2) They want to reduce the overall length of the chain....so that there
is less slop that the derailler has to take up when running on
smaller (rear) rings. This should lead to fewer instances of the
chain coming off of a front chain ring and make shifts smoother.
For those of us with chainstay mounted Ubrakes, this would also lead
to less chain suck.

| Short cages are better than long cages, but not a lot. Smoother, lighter,
stronger, less apt to get bent up, etc. I suppose the pro's don't need the
widest possible gear spread so short makes sense. I have a long cage on both my
mountain and city bike. The city bike (an old Hard Rock with slicks and low-end
Suntour comp's) always had one and the mountain bike (a Bikeology special with
Deore XT $tuff) has had both. The mountain bike now has a long cage in order
to handle the big gear that is on a spare wheel that I sometimes use and the
rest of the time I just have to put up with the extra hassle and work (I guess).
The Best way to cope with the extra hassle and work is to eat a chocolate bar
before and/or after a ride (only allowed if you have a long cage!). The
chocolate will replace the calories used up because of the extra cage and chain
weight and will help with the depression that gets caused by the slower and
sloppier shifting as well as the stress from worrying about the bending the
longer cage.
I have yet to smash up the long cage (knock on wood please) on my mountain bike
with the Deore XT stuff. Back when my city bike was still a mountain bike and
spent time in the woods it used to go through Suntour long cage derailliers like
crazy. Sticks would jump up and jam themselves in them and presto its,
pretzelville and a walk home. Guess its long (and strong) cages and chocolate
bars for me till I get drafted by one of the ATB racing teams...
What about the new micro stuff? Can you get both long and short cages?

I believe the Suntour Micro Drive claims to be the shortest cage and as
with the XTR, I don't think there is an option - one size fits all?

| 2142.5 | 1 4 long cage | COMET::VOITL | | Sun Dec 15 1991 22:51 | 9 |
| I am in favor of the long cage. I do ride the mtb on the road
sometimes (crazy huh, oh wheel helps keep me humble yeah, I have a road
bike) and there are a few trail rides I do that are long and flat. I
have also been known to use the 42 or 46 I forget the size on long
decents. I also enjoy the the full range of gears. I am also
contemplating putting a 50 tooth ring on the bike for even more speed.
Wheel there is my 2 cents worth.

| 2142.6 | Stick a 50 on the from of yer bike | HERON::MARTIN | I don't have an attitude problem!!!! | Mon Dec 16 1991 05:15 | 4 |
| I agree with -.1, I run with 24x36x50 on the front and a 12-30 on the
back on my mountain bike. Short cage wouldn't be able to handle that
