I've been working on finding the "right" position on my bike, especially in the aero bars.
What is the "right" position?
Ultimately the right position is the one that enables you to generate the best possible results while still being comfortable for the hours and hours you'll spend on the bike.
The main keys are the hip and shoulder angles, both should be 90 degrees. I had my wife take a picture of me on my bike, then I figured out what my angles were.
The first picture, with the lines drawn in:
Pretty close actually. As you can see, though, my shoulder angle is too acute (less than 90 degrees) and my hip angle too obtuse (greater than 90).
I still had spacers on my headset, so I removed all of them and dropped the handlebars down as far as they will go.
This is the final set-up I came up with, it pretty closely matches the angles from the article.
I also measured my knee angle to make sure my saddle was the right height, it seems OK. The only thing is that I'm not sure while I'm pedaling if my heal is dropping down, which would over-extend my leg. It feels comfortable, but I may take some video to analyze my pedal stroke in a bit more detail.
Any comments/feedback is appreciated!
Update...
After I posted this blog entry, I received some advice from the good people at Trifuel.
- Seat too high - my knee is too extended in this position, I need to drop the seat a little
- Flip the stem - I should be able to go lower and get that hip-to-back angle to 90 degrees by flipping the stem
I'm really happy with the position - you can see how flat my back is compared to where I started! I had a two hour spin class today on this bike/trainer combo, and it was completely comfortable. Dropping the seat also really helped my pedaling, I felt much more power at the bottom of my stroke as I could get my heel down properly.
Thanks again to the folks at trifuel - great feedback. :)
