Elite  3498     Laguna Beach |  Subject: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings.Not ten minutes ago on my ride into work I was passed by a rather sensational sight. A jaunty young couple astride one of those sensational looking Asian racing motorcycles passed me going, of course, very fast. The young lass on the back, clinging to her beau for dear life at the break-neck speeds they were travelling, had inadvertently worn jeans that were too low and knickers that were too high. ( no jokes about the frequency of my panty-posts- I can't explain it...) What was fascinating was that, as the boundary layer of air surrounding this sporty couple attempted to reassemble in their aerodynamic vortex it also lifted her top, revealing that she could have done a better job matching her intimate ensemble for today. Anyway. It got me thinking about the aerodynamic implications of rear hydration units and how much differently air would perform at lower speeds. I estimate these two were going over 50 M.P.H. ( in a 35...) so the aerodynamic effect is exponentially larger at that speed, over double the normal ground speed of a very fast triathlete on the bike. I've long been convinced that integrated hydration and accessory carriage like we see from Trek and Cervelo built into the bike is not just a small improvement in aerodynamics, it is enormous- as this young lady's sensational high speed wardrobe failure may suggest. Anyway. I need a Red Bull. Here's a one of these things, which I really like:

Expert 911 Casa Grande | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. Tom, Great post and me thinks you have spent too much time at altitude. Would have been a better story if said girl hadn't tried to match at all. |

Veteran 258 South dakota | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. at what point does all the aerodynamics become all for naught? if the bike has the drag of a mosquito but the the motor can only go 15mph then......
more importantly did the software clash with the hardware? Edited by Sdboy2 2012-06-21 10:36 AM |

Master 6834 Englewood, Florida | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. So, you looked at that and pondered the aero effects? I'd suggest maybe a bit less training and some time spent on, uh, other pursuits. |

| Elite 3498 Laguna Beach | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. "I think it has been realized now that those rear hydration setups generally aren't that aero. They should probably be left for long distance solo trips and not for racing." Bingo. The challenge with carrying adequate hydration isn't really race day. That's "catered". You only have to go about 5 miles before you hit an aid station so you only need enough stuff on your bike for that 5 miles if you planned well. However, when you go for a long training ride its a different story, and that is where carrying a lot of nutrition, fluids and spares becomes a challenge. It's interesting the Camelbak hasn't caught on better in multiport. I think Camelbak is very close with their new lumbar hydration reservoir packs and their undervest thingy made for cycling. But somehow those haven't captured athletes' attention like rear mount hydration rigs.

They should probably be left for long distance solo trips and not for racing. And I know that those front mounted ones aren't that great either, though I do convince myself that they are better as I don't have to reach behind me to take a sip.
My trip to the wind tunnel (and Cervelo's) would suggest the opposite. Rear hydration was one of my better options. |

Sdboy2 - 2012-06-21 9:35 AM at what point does all the aerodynamics become all for naught? if the bike has the drag of a mosquito but the the motor can only go 15mph then...... This is (one of) the biggest fallacies continually repeated on this (and other) tri forums: "I'm not very fast, so making me more aerodynamic is worthless!" No. Precisely the opposite. Greater aerodynamics benefits the slower rider more (in terms of time saved). Furthermore, aero improvement has nothing to do with engine work. Do both. Carry on. |

At Cervelo's annual BrainBike symposium they usually have an excellent presentation that showcases the mathmatical relevance of aerodynamics at lower speeds. It's eye-opening. |

| Regular 234 Chicago Area | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. Of course it goes without saying that TPIWWP. The bigger question one must ponder here, is while the upper and lower underbritches (as Larry the Cable Guy calles them) were mismatched, one then cannot help but to wonder whether or not the carpet matches the drapes. |

Since I am a slower rider I will head directly to the LBS to buy the tri bike I've been debating. This post will justify the purchase to my wife. Thanks! |

| Veteran 480 | Subject: RE: The Girl in the Thong on the back of the Crotch Rocket and other Aerodynamic Musings. I believe the fashion look the young (?) lass was sporting is called a "whale tail", which is not only quite out of style, but quite non-aerodynamic. Hydrodynamic, perhaps? |
