Re: saddle position: Bikefanclub.com

MadRocketSci,

My saddle is positioned fairly centered on the rails. You can see a picture of the exact setup I'm riding on this website in the Production bike Photo Gallery. I don't know the exact measurement of the saddle position behind the bottom bracket in centimeters, but I do know it places my knee (tibial tuberosity) about 1cm behind KOPS. My kneecap is practically right over the pedal axle. On my other bikes, I'm further back.

The net effect of the more forward position is that I ride with what feels like noticably "more power" than my other bikes. I feel like I can push it harder and ride faster and with less fatigue than before. This is all very subjective since I don't have a true power meter to measure the difference in watts. For all I know it could be less watts knowing how bizarre things tend to work but for now, I feel very dialed in and happy on the Trek. I love the position and I wouldn't want to go back.

As for climbing. No doubt the bike's light weight (helped by the wheels) really makes a difference. Like most people, my position when climbing alternates between seated and out-of-the-saddle but when I'm sitting, I don't feel the need to adjust my saddle position. It just feels right.

Hope this helps.

-K.

P.S. Here's the same images I posted in response to c40's suggestion that I was wrong about the bottom bracket position on the Trek. As you can see by the red line that follows the angle of the seat tube, the center of the BB shell lines up with the rear of the seat tube, not along the seat tube centerline as it does on most other bikes. So the question becomes how does Trek measure (ie. report) their seat tube angle measurement - is it the actual angle of the seat tube, or the steeper, virtual angle - for example, as if you had left the red arrow pointing at the BB center but moved the top arrow to the center of the seat tube?

Same thing with the Madone...
