How do we determine the optimum contact points? How do we even measure what we have? I feel I am close with my Strong and with my Merckx, which are set up to within MMs of each other.
Serious question. BTW, trusting the builder is a big leap sometimes. Even though they surely know more than I do. |

when your pants droop you get braces, right? are you riding efficiently? does exercise induce pain or injury? you will know best what is and then you will ceased fidgeting with the "numbers". if trusting a builder is a leap, why? i trust airline pilots! e-RICHIE©™® |

I am glad you trust the pilots!
Riding does not induce any pain and I have a flat back position. I feel it is efficient. I am a perfectionist and always think that pretty good is not good enough. You can see my Merckx under "the slow merckx in question" in the custom gallery here. There you will see my position, or at least one which works for me, but no picture of me on it. But even though the bars are low and the drop pretty great I almost feel like they could be lower. That is what I mean. How low is too low? Maybe when I am back out east I will have to visit a builder and make the leap of faith. I was once measure by a pillar of American framebuilding, but got cold feet. My bad. BTW, pilots tend to be control freaks. I am no exception..... a bad customer would say some...... |

Excuse me, but what is 'l' called and what is 'R' called?

I is called frame setback
R is called saddle nose setback S is called financial setback e-RICHIE©™® |

BTW, I guess that various size cycles, including the excellent one by Serotta measure the contact points more than the lengths, though those are the numbers that end up being used.
I once used one and it seemed pretty cool. I guess that would be a way to let the customer work with the builder and get something right. |

that's "half" of the it. creating a useable design incorporating the static contact points is a builder issue, not a fitter issue. hey - thanks for reading. e-RICHIE©™® Last edited by e-RICHIE; 08-07-2005 at 07:18 PM. |

word. i've seen size sheets where the fitter spec-ed in the geometry too. checks and balances are in place. kool. e-RICHIE©™® |

e-RICHIE,
I'm confused again. What relevance does the 'l' measurement have? Doesn't the rider's position relative to the bottom bracket also depend on how far the post is extended. If the post is extended farther, then the rider moves rearward, and if the post is shortened, the rider moves forward, yet 'l' would be the same in both cases. So, it seems to me if someone said my frame setback is X, that wouldn't tell you much about their position relative to the bottom bracket. Last edited by Needs Help; 08-08-2005 at 01:22 AM. |
