Why should it be any more difficult than buying one of your Canyons? 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. Mythology Jay. Cycling is rife with it and you know that. |

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. 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 And those saddles were absolutely horrible. A leather saddle that would take a year of heavy riding to break in or a Regal saddle that would chaff you between the legs so badly that you could hardly walk after a long ride. Those were terrible, terrible times! Oh, the agony bicyclists endured! The only people on bikes back then must have been the crazies and the masochists.

No. It used to be that stock frames came in 2cm increments from 46 cm to 64 cm so for most riders it wasn't necessary to order a custom frame. You might need to change the stem reach a little but you could get very close to an ideal fit unless you had short legs and long arms or vice-versa. When I bought my touring bicycle, a 57 cm would have been ideal but I had to choose between a 56cm and a 58cm. At the time, the conventional wisdom was to go 1cm up for touring bicycles and 1cm down for road bicycles, so I went up. That was fine when I bought it, but 34 years later it's too big for me. I have to disagree with you. Most frames come in 7 sizes now. That is not different than in the past. The frame I am looking at comes in 50-52-54-55-56-58-60 cm effective top tube length. I'm about medium so I can choose between 54-55-56 cm. Most fitting programs advice a 56 cm frame. Most of the time I end up with a one size smaller frame. I'm still quite flexible in my back (still can lay my hands flat on the floor standing up) so a lower handlebar is not much of a problem, within limits of course. It is the reach I find uncomfortable. After 34 years you entitled to new frame I would say ;-) Manufacturers got tired of manufacturing ten different frame sizes so now they'll make four to six different "compact" frame sizes and use various combinations of seat posts, stems, and spacers to make things fit─kind of, sort of. It's like the old Midas Muffler commercial where the customer asks "do you have a muffler that will fit my car" and the mechanic answers "fit? we'll make it fit" and proceeds to use a collection of adapters to create something that can be used. I'm a big fan of long head-tubes and over time the head tube got longer that is good. Look at my Litespeed which has a relative short head tube This approach has benefited custom manufacturers. One short friend of mine ended up with a beautiful custom titanium frame road bicycle. Because a triple crankset is preferred in this area, especially for older riders, she had to go with a Shimano 105 group. You have to have quite strange proportions to really need a custom frame these days, but it can happen. Friend of mine is short and has a long torso. He is always struggling finding a frame. Lou |

Yes, stock frames came in 2cm increments with often dreadful "scaling up" for larger frames that ended up with too short top tubes. Even after the LeMond longer top tube revolution, Colnago steel frames in 1994 in the 63cm size (my size) had TTs that were a full 1 -1.5 centimeter (not mm)shorter than current sizing conventions. https://saarf00.files.wordpress.com/2012/12/21.jpg It was more likely that you would need a custom frame back then than now. Also, back in the day, it was all obscure knowledge and mysticism about how one should fit on a bike -- flat back, hump back, KOP or not, etc., etc. There were no fit kits and master fitters and all the things that lead to prescriptive size and position that are popular today. Even custom builders back then tended to make bikes with shortish top tubes. I had five custom steel frames built for me (ultimately all broken or stolen). When I cracked a head tube lug on my racing bike in 1984, I needed a quick replacement and found a first generation Cannondale at a local store. It fit great, and I never looked back. On a lark,many years later, I re-brazed by broken racing frame and brought it back from the dead. Even with a 13cm stem, the TT was too short for my tastes. I couldn't imagine how I raced that thing and loved it. -- Jay Beattie. |
