It's designed that way so that the rider can get very close to the motorcycle for an event called derny racing. http://elcyclista.com/wp-content/upl.../03/track2.jpg |

These bikes are setup this way for 3 reasons: 1) You know how we can go much faster on rollers than we can on the road/track? It's because there is no air resistance. The front wheel is set up (reverse rake fork, 650c) to allow the rider to get as close as possible to guy breaking the wind for him (haha...fart joke). 2) It's easier to pedal super high cadences when you are very close to the bottom bracket. This is why he is on the nose of the saddle. This is also why Japanese Keirin bikes have really upright seat tubes...because they are not allowed to use big gears that modern riders use, so they have to spin super high cadences. 3) It's easier to pedal high cadences when you are upright (hip flexors engage more), but upright isn't aero. That's why you don't see riders riding upright at high speeds it's because the wind will limit their speed. But, this isn't a problem here because the motorcycle driver is STANDING to block the wind. Also, if you could see the motorcyclists' helmet, you would see that it has some cups off to the side that are open to the back. This is so that he can hear commands from the rider like "Whoa!" and "Allez!" (faster). http://4.bp.blogspot.com/-Y2RW40P6h5...07_cycling.jpg |

Really? I always have a harder time spinning down hills on the hoods than in the drops
Maybe you are using a different pedal stroke? |
I dont have a trainer, but I know what you are talking about from when I mess around with one leg drills. I dont have an explanation, up to around 100, maybe 110, I just feel clunky and it is harder to follow the pedals or increase the cadence if I don't get low.

Was looking through some old photo albums and thought this might amuse some of you. This is a cobbled together commuter I was using last fall between bikes. Yes, that's a 27" front wheel with a 700 back. The fork dropouts were too small in front. :) |

Sorry for the crappy phone pic. I like how the spot where the rear brake lever should be is covered up with the same electrical tape that the kickstand is taped closed with. |
