booty position on the saddle(6 posts)

booty position on the saddlewulf
Jun 28, 2002 5:40 PM
I've been playing with my saddle height and fore/aft position to help minimize a slight nagging knee pain I get after about 25 miles of riding, and I had a "eureka" today on my position.

As I was REALLY pushing it today, I felt myself ooching up on the saddle instead of really sitting back on it like usual, and my power felt superman like. I wasn't so far up that my saddle was a butt-spear, but pretty far up - my booty was probably at least 1" more forward than usual (I was riding single, so I don't have independent verfication of that, though...)

The problem is that it makes it a little more difficult to get in a low aero position...but felt like I had a lot more power. It's still comfortable when I'm just chilling upright to have my butt back on the saddle in its current fore/aft location, but is changing position on the seat THAT much a bad idea otherwise?

Anyone else change their position alot for certain types of riding? cruising around vs. hauling ass?

you ever hear the term 'sitting on the rivet'..? cause that is likely what you were doing...
yes moving forward on the saddle is/can be a power position...
you 'ride' a saddle you dont just sit on it like a log...
torque and cadence....C-40

Remember that power equals torque times cadence. Torque and cadence are equal contributors to power output.

Next time you're up on the saddle, see if you notice an increase in cadence as the primary contributor to the "power" increase.

Generally, sitting further back increases the ability to apply torque for climbing, but reduces cadence. Moving forward has the opposite affect. The trick is to find a position that is between the extremes.

You may have the saddle too far back, if moving forward more than 1-2cm truly enhances your power output.
thanks for the comments, guys (nm)wulf

ever see the pros on their time trial machine? They all move the seat forward, or simply move their butt foreward, some even go for the extremes of sitting on the tip of the saddle. I felt having you butt directly about the bottom bracket makes your legs in a better position of power pedalling, since you are pretty much "stepping down".
Yes, moving your body forward makes it harder to get down into an aero position, that's when you need an aerobar, to get forward while still get down. I was playing with my clip-on aero-bar the other day, trying out both my regular road position and time trial mode, difference is unbelievable, as soon as I moved my butt forward and get on the aerobar, man, my speed went from 20mph right up to 26-27mph.

Interesting...I don't know enough about TTing (read:nothing)to have known better, but that's what I was thinking. I was just cranking away, and dropped the two people I was riding with - my mph went up substantially, and I held onto it for about 10 miles. Great feeling. I may look into some aero bars now, thanks for the post, Qubeley.
