    Default Fit Guru of Fit Gurus

    Most of you on this forum have forgotten more about bike fit than I will know, but this post from an eBay sale sure seems to be an easy formula for ensuring a good bike fit...who knew it could be so simple?

    Please make sure you need a 54 cm bike prior to ordering. If it helps I am 5'8" tall with at 32" inseam and the bike is a great fit. I would think anyone from 5'6" to 5" 9" with a 32" inseam would be good to go on this 54 cm frame. If you have more than a 33" inseam or less than a 31" inseam the bike probably won't fit. I will let you decided if a 54 cm is right for you. I can take no responsibility for fit.

    all formulas - such as they are - need to account for foot length atmo.

    Crank length is important too.

    I've got a buddy that is 5' 9" at most wearing a size 12 shoe. He rides a media Look and has the saddle slammed as far back as it will go with a 25mm setback post. I haven't really examined his position, but he seems happy with it. Sure makes for some interesting thoughts.

    in cycling. foot length is part of the saddle height/pedal stroke equation because you
    pedal with the ball of your foot atmo. ps i never understood why folks often bring their
    pants inseam into these conversations; it's an irrelevant detail.

    Probably so, since if it was critical we would be discussing girth as well. However, as I am no expert on bike fit, I will defer to those with more experience in this matter.

    So I posted this post (from my office in the Dept of Redundancy Dept), and based on the replies, I'm right to keep saving my dollars and get a fitting frameset from one of our distinguished builders some day, hopefully sooner than later. Thank you and Happy Friday!

    Depends on what you want. My custom bikes haven't been purchased with fits in mind. Moreso I wanted certain stuff-n-things that I couldn't find on production bikes.

    sorry guys. but the guy posting the ad isn't saying anything that isn't true. a 54cm frame should fit someone who's 5'8.

    no it's not. the center of the circle stays in the same place regardless of crank length. you don't change your saddle height if you change crank length. not much happens at the bottom of the pedal stroke anyway.

    In defense of the eBay poster, I think his point is that he is not giving a buyer their money back if they get the bike and find out it doesn't fit.

    in the unlikely event that your crank length changes by more than a 10mm, youd likely have to change the shell to saddle height very slightly.
