Climbhoser: like you said my saddle position is correct so I took some time to think about what you wrote about body position and realized that is the answer for me.
When I followed your trainingbible link I saw the comparison pic between the two riders and it immediately clicked.
my posture is (soon to be was) like the guy on the right. I wasn't tilting my pelvis and keeping my back straight. So this morning on the ride in I took some time in the driveway to figure out how to sit like that and how it feels and you were absolutely right, Its like I gained a couple inches of reach.
I noticed over the 6 miles I commute that I was breathing more freely and at a lower rate and was able to keep my cadence up where i've been trying to get it to for the whole ride. About 5 minutes after I got off I felt like someone punched me in the stomach...my core is obviously weak. moreso than I thought.
So now I'm amped to work on my body position and strengthen my core...snowboarding season starts soon and I'm gonna have uber balance if this strengthens it.
