Rainy Day TT Positioning Activity - Garage Wind Tunnel?
Had the day off for President's Day, but it was raining, so I fiddled around in the garage a bit. Originally, I wanted to see if I could set the TT bike up in a UCI legal Superman position.
I thought that I was pretty successful - y'know, I whipped out the look ergostem and tried to make the bars even with the top of my saddle. Next, I put the ends of the extensions right at 75cm in front of the bottom bracket. I took some video of me riding in the position, and it felt eerily familiar. yep, I'd basically re-created how I have been riding for the past 9 months or so!
Seein' as how I had the fiddle-with-your-position bars out, I figured I'd just do some fartin' around with the whole forearm angle thing.
I shot some video and tried to do a sweet voice-over/narration (that's a link to a *.wmv) of the exercise, and have quickly come to the conclusion that I need some practice doing the voiceover thing! Holy cow that's pretty funny! "Fiddle-futzin!" Oh dear...
:-)
Check out what happens to my shoulders when I do the snowplow thing with my forearms with wide elbows (ala Jan Ullrich) - pretty crazy, huh!? Here's the lo-fi version of the video (sans my sweet narration!) :
Here's something similar when I have narrow elbows (not as big an effect, but still there):
The side views during this exercise also show how stable the rest of the body is when elbow position is more or less controlled for - the exception appears to be when doing the snowplow to the max - that's just not going to work out, eh?
What was my point with this whole thing - oh, I don't know if I really had one, other than to encourage everyone to try stuff out when it comes to your TT position. You never know the things you might notice when using something as simple as the supercomputer between the ears, a video camera, or even pedalin' in front of a mirror!
Have fun with it, and I'd encourage you to not "sneak up on the problem". Fartin' around with a cm here and a cm there is a good way to confuse yourself. Big changes at first and explore the design space - that'd be my recommendation.
Peace,
