Downhill tuck, BOTH hands behind my back ...(15 posts)

|... yeah, that's right, I'm totally insane. I actually tried it. And lived.
This is the next illogical step after the discussion last week about the both-hands-near-the-stem aero position, then someone suggested one hand behind the back.
The bike was, of course, the cruiser. I still had braking ability (the coasterbrake). At 30+ mph it is as stable as a Harley, plus the bike path had no possibility of cars, nobody else on it, straight, and I'd been over it a few minutes earlier and knew there were no obstacles. These tests were on mild grades, maybe 5% at the very steepest, maybe half a mile long.
The aero tuck: feet at 3 and 9, knees together, butt off the seat and the nose of the saddle held between my legs -- this lets me get my back flatter and the knees together supposedly reduced drag. I don't think I could get my nose as close to the stem this way, though.
Net result, I didn't break any speed records. But I didn't break any body or bike parts either. One hand behind me may have been slightly faster, as it let me get my back flatter. Plus, pedaling up the next hill was uncomfortable -- pinching the saddle like that caused a tender spot on my legs.
Don't try this at home. It doesn't work well enough to bother with.
This is right up there with my donut diet (it works, it works better if you drop from 2 donuts to 1. It works even better if you drop to NONE).

|I don't ever want to hear anything about my downhilling being crazy. No hands is just plain nuts! Just think if the liability if you'd hit some poor rollerblader...|

|HH you are truly the man. I would PAY MONEY to see that!! Hell, I might just mail you $1.00 for being so crazy. With your innovative training/dieting methods you'll surely put Ferrari and Carmichael out of business. If I tried that I would break every bone in my body. Good thing you didn't get hurt.|

|I tried that a couple of years ago, but I don't think I was going as fast as you were. I got the idea from watching some videotaped race coverage and there was a shot of Dmitri Konychev doing the same thing; stretched out with his chin near the handlebar and both hands behind his back like a ski jumper's tuck. It's certainly crazy, and I haven't had the guts (or is it lack of sanity?) to try it since.|
|Its probably actually safer if done faster ...||Humma Hah|

|... the bike is more predictable no-hands at speed. But you gotta understand, I ride the original "look, Ma, no hands!" bike. It was BUILT for this.
The thought of doing it on a roadbike simply terrifies me.

|I was on my road bike when I did it. Probably going @ 27mph. Couldn't have done it much further down the hill (i.e. faster) because the pavement got a little sketchy for such maneuvers.|

|When I was a junior ski racer I found out from some wind tunnel tests that putting your head between your legs when you were in a tuck was very aerodynamic and therefore fast. ;) I tried it in my next Super-G. Went through numerous layers of B netting that day. Non-scientific, but I think I was going pretty fast though when I exploded. Better luck with your tuck.|

|Any skier could've told you that. |
Take your helmet off it's even faster.
BTW - donuts = fat pills

|no helmet and naked...but you need to shave all your hair off to really make this work|
|One step beyond aero bars||DCP|

|Mouth bars. Control steering with your teeth while being as aero as possible. AKA dentist and physician full employment bars.|

|when i was a junior racer in philadelphia.. danny fox used to descend hands behind the back to goof off on a regular basis.. danny went on to the national team and was a pro for a few years.. posted some nice rides at corestates..
silly but fun.. as long as you don't crash..
|how long no hands?||ET at home|

|Seconds, or long enough to test the aerodynamic properties of the position?
Here's a tip to try on your next descent: unclick your cleats, put stomach on saddle, legs in air straight behind, so you're just a slim, horizontal, super-aero stick. You can do it!
|About a minute ...||Humma Hah|

|... I typically spool the bike up to about 24 mph coming across the top of the hill, tuck, and try to ride no-hands to the bottom.
That stomach on the saddle trick occurs to me every time I think about aero positions. I'm running platforms (clipless on a cruiser is just WRONG). But the original Schwinn cruiser seat would be better (it was as wide as a sofa). I've yet to try that position -- probably should do some additional core-strengthening exercises first. And have my head examined.

|Try taking your feet off the pedals. Legs straight out behind you stomach on the seat hands on the center of the bar elbows tucked in. Now that's aero.
Of course you could just get a recumbent once the full body cast comes off.
