sorry, i never saw your post about stock vs. custom frames. i've been out of town and then in a training course with limited net access (the horror! ;-P)

some answers for ya:

re: crank arm length.
i run 170's rather than 172.5s' because i found that the extra 2.5mm required me to drop my saddle too low relative to my bars. to be honest i'm not sure whether i've got long femurs or not. i have long legs, but i think that they're pretty proportional upper vs. lower leg.

re: custom vs stock frames.
i'm actually 5'1" (so i'm 6" shorter than you!!) with a 31" inseam (yes, freakishly long legs!) a short torso and fairly long arms. both my road frames and my hard tail mtn frame is/are stock frames. my full sus mtn frame is custom with a super short top tube. i have not had too much trouble finding stock road frames that i can adapt to my proportions. my trek 5200 (which is my main ride on the road) i bought the frame/fork only & did the build myself. the frame is a 50cm & to accomodate my short torso i'm running a 70mm stem. having long legs has helped me in terms of finding a stock frame because the problem that most short women have is that they don't have stand-over. i have stand-over and then some! for me it's just a matter of adjusting the reach.

i also thought about looking at TT bikes that had a square geometry (top tube & seat tube approximately the same lenght or even top tube shorter than ST) but found that the Trek suits me.

my other road bike is a 49 cm bianchi Giro and i find that the reach on that bike is a little too long for me.....hence why i bought the trek!

hope this helps.

you are kidding, right?Steve_0

you can feel the effect of a 2.5 mm delta in bar drop? The padding in my various shorts varies by more than that. Wish I were that in tune with my body.

On second thought, no i dont.
nope_rt_

i can feel a 1mm drop in saddle height without changing anything else. i thought everyone could! adding 2.5mm to the length of my cranks meant dropping my saddle to accomodate. the end result was not comfy.

seriously, i thought everyone could feel micro changes.

rt - apparently way too in tune with my body! ;-P
in tune with your body, or out of tune with your mind?Steve_0

I wonder if you'd feel the effect of 1mm change if you were unaware of the adjustment.

BTW - just kidden with the subject line; I just can't fathom it.

including as you say which shorts/pad you're wearing, I can't fathom noticing a change the approximate width of a credit card either. But then, as my wife constantly reminds me, I'm an insensitive lout.
how the heck do you measure it?terry b
Jul 17, 2003 9:50 AM
I mean really - when I'm setting up my saddles and eyeballing the spindle to saddle top I'm guessing I'd be lucky to hit +/- 3mm. 1mm is the 1/3 distance between these two lines ||! How do you control the thickness of your chamois? I'd be willing to bet that the pad in your shorts changes by that much after the first washing.
why is everyone getting so stressed about..._rt_
Jul 17, 2003 9:59 AM
what *i* think i can feel?! yikes, folks, if i think i can feel the difference then i can feel the difference! sheesh! ;-)

maybe you guys are all just jealous! ;-P

rt - tongue in cheek, of course
I'm with you...MShaw
Jul 17, 2003 10:25 AM
...but then again, I pay attention to stuff like saddle height, etc. (No tongue in cheek)

I have friends that you could move things by 5mm and they wouldn't notice. Not me. Oh well.

To each their own!

I'm just amazed when people say things like you've said and am very interested in the techniques you use to render that level of control.

I am extremely obsessive about the set up on my bikes. I've even built a jig to set saddle height and saddle fore/aft and I keep track of these measurements. However, with all my obsession and tools I sincerely doubt I could control any setting on my bike to +/- 1mm which is what you say you can detect. The variance in you body mechanics from day to day alone should swamp that miniscule amount.

I'm not questioning your ability to detect it, I'm curious how you measure it and control it.
well, i'm just an amazing person ;-)_rt_
Jul 17, 2003 11:01 AM
i don't think i can tell you how to render that level of control or how i do it. maybe it's because i'm not that anal about my set up that i can tell. or maybe it's because i've spent years & years & years learning to be in tune with my body and where i am in space.....and i mean that seriously. a combined 25 years of gymnastics, classical dance, springboard diving, and synchronized swimming has made me learn, or at least given me a keen awareness of my body and where i am relative to other things and myself (both when i'm right side up and when i'm up side down!)

on a day to day basis i don't even try to control the 1-2mm difference between this chamois or that one, but i do have shorts that are more comfortable to ride in and those that are less comfortable. everyone does, maybe it's because everyone is picking up on those 1 mm differences.

I can testify that RT's custom FS mountain bike is teeny tiny :) I had the pleasure of riding it around a parking lot. My custom steel hardtail (all 13" of it) made her custom look tiny.

I'm 5'3" (no clue what inseam) with longish legs and a short, short torso. I ride a 46 cm road bike with 50.5 cm TT, and it's a bit too big. I plan on getting a custom next year with a 50 cm TT.

It's going to be interesting trying to get my new cross bike to work with a 51 cm TT. I'm thinking of running a 50 mm stem if I can find one...
Thanks!Kristin

Good information. Just one other question. How much of a drop do you keep between your saddle and your bars. The biggest difficulty in stock frames for me, seems to be getting the bars up high enough for my liking. The very best I've been able to do on the Bernardi is 2.5" when I have my saddle set properly.

Interesting point on the cranks. I hadn't thought about the fact that you must lower your saddle to compensate; but of course, you must. I'd welcome it! :-)

Thanks again
any time! (more...)_rt_
Jul 17, 2003 9:55 AM
i'm not sure how much drop i have from saddle to stem on my trek, but i'd guess it's around 2.5", maybe more....i'll have to check when i get home! i know that you can read the word 'Thompson' on my seatpost....on my bianchi you can't read all of 'Syncros'. it reads 'Sync' and the rest is swallowed by the clamp & ST. :)

One of the historical pieces that OLN has aired in conjunction with the TDF talked about Eddy Merckx and attention to these details. He would show up at the tour with up to 16 bikes and would sometimes have his mechanic make 1mm saddle height adjustments to the bike he was on during a stage. Could you be the next Eddy...okay Edie? :)
always nice to be in good company :)_rt_

don't think i'm the next Edie though!! hehe
