there’s a thread asking about “will my LBS help me find a size without paying for a bike fit?” yes, of course they will. however, how good is that recommendation? who knows?
so i’ve been pondering a project with a bike company, which is IN NO WAY EQUAL TO A QUALITY BIKE FIT SESSION! but it could still be an interesting exercise.
basically, i’ve been playing with, you give me your overall height and your saddle height, here is your pad x/y. now, this is about analogous to me asking you for your overall height and your ear size and i’ll tell you what size shoe to buy online. the precision is not going to be there. however, who knows? maybe ears and feet are closely correlated?
so, if you’re interested in participating, what you need to do is this:
give me your overall height, and the height of your tri bike saddle, bottom bracket to the top of the saddle, 4cm back from the nose.
you need to ACCURATELY measure the pad x and y (pad x to pad-center).
if you do those 2 things, then i’ll generate a pad x/y for you and we’ll see how closely we correlate. then perhaps i tweak my formula based on what we find.
if you’re game, then give me height and saddle height below. but ONLY if you feel you have a pretty good position on your bike, and only if you can and are willing to accurately measure pad x/y to pad center.
I would consider adding in-seam measure as an important way to convert height to an X/Y measurement.
This is a relatively easy thing for people to measure.
Offset the inseam measurement a few cm’s and you’ll know the point that they rotate and how much height ought to contribute to X vs. Y coordinates.
