hi. i have been uncomfortable on my bike for the last bit, and started looking into bike fitters. i've also looked into the 'literature' and found the formula (which i believe is the "lemond" formula:
saddle top-to-bb distance = inseam X .883.
this puts, me, a 5'10ish rider with an inseam of 31-32 inches at a height of 69.3 cm. i measured my current height and it was 73.5 cm. my mountain bike, with its saddle in a position that i consider to be low enough for me to bail easily, but not necessarily the best power position, is at 68cm. this is surprising to me. i am, by no means, saying that i am right in my self-positioning--it's just surprising.
so my question is--where is your saddle height relative to this formula? 4 cm seems like a lot for me to be off. any recommendations? any success stories of lowering your seat (gradually of course) 4cms and feeling better on the bike? definitely it seems like i'll breath better with a less acute angle in the abdomen-thigh area, but what about power and minor things like that?
thanks for the input.
