Bike adjustments
As part of the ordering process of my gravel bike I was measured last Wednesday to determine the correct frame size. The measuring program didn't take the handlebar/shifter/shifter position into account in contrast to saddle make and type. I found that strange because most of the time you are riding on the hoods. It was a rainy day yesterday so I took the time to measure all my current bikes which I adjusted by 'feel' giving the purpose/riding style of that bike. Results:
https://photos.app.goo.gl/1HbWyM6g1gNqoyMx5 So today I went back to the LBS (another 100 km round trip) to discuss this.. In the meantime the manufacturer emailed the shop a drawing of their proposal. Strangely this drawing did show the measurements of the position of the shifter on the handlebar and this came very close what I measured on my bikes especially measurement E, F and D. With the mechanic we figured out the correct frame size taking the chosen handlebar, a stem length of 110 mm and the new Ultegra shifters and the manufacturers proposal/my measurements into account. My question is what do these measurement programs exactly do? Are there people that close a bike only based on these measurements? Lou |

Why should it be any more difficult than buying one of your Canyons? The measurements are intended to impress you. Shop drawings and proposals? What, are you buying from General Dynamics? What are you buying? Back in the day, seat tube length was a big deal, but now with compacts and long seat posts, the important measurement is TT, so I suppose they're trying to get your TT just right to size the bike with a stem that is not too short or too long, which might affect steering in some metaphysical way. Unless you're built like ET, they'll pull a "medium" out of stock, declare it custom and hand it to you. -- Jay Beattie. |

In Europe bicycle manufacturers take themselves and their customers seriously. What does it even mean that your bikes fit you to within 1mm? 1mm of what? My bikes fit me exactly because I have adjusted the saddle height, position and stem length and rise (or purchased a bike with appropriate stack height so I don't need rise). My bikes are exactly fitted to me even though my frames are all over-the-counter. And my fit changes as I get older and creakier and less flexible. Assuming you had long legs and a tiny torso, you might need a custom frame with a short TT and weird geometry, but assuming you're not misshapen, what basic dimension of your bike is any different from a similarly sized bike with basically the same geometry, vis., the same type of bike? -- Jay Beattie. |

Yes that is what I thought. 7 body measurements (left and right footlength ???) which resulted in 19 adjustment proposals, even a seattube angle of 73.74 degrees. WTF? Bike will be custom build (parts) but frame will not be custom. I just wanted the right size to begin with (over-the counter) and not ending up with a 80 mm stem. These are good guys btw but they soon found out that I'm not the average customer ;-) They are dealers of BMC, Cannondale, Cervelo, IDworx, Santos, De Rosa, Bianchi and the brand I'm buying now which made me part of an American family. How about that for marketing ;-) Lou. |

All that stuff about measuring your foot length and recommending funny ST angles is probably because it's working out how to get your knee over the pedal spindle (see https://www.sheldonbrown.com/kops.html).
There's a lot of opacity around how these fit calculators work. I think many of them just produce numbers which are simple linear combinations of the measurements you put in with builtin coefficients. |

How about that for marketing ;-) Lou. It used to be much simpler. Buy a bike that you could stand over; set the seat height and position; set the stem position; ride the bike and make any more changes. It still works for me :-) -- cheers, John B. Yes I remembered that time, where all frames had horizontal top tubes, only 2 saddles and handlebars to choose from and of course that awful quill stem. Most of the time people rode to large frames. That time passed thank god.. Lou |

Tommassini actual built a totally custom frame for my friend but it was only mm different from a stock version. But it was one of the custom old-style steel bikes. His wife was measured and hers was exactly the stock size. |
