Good idea- pick a current Gunnar color and call me. With the proliferation of models, sizes and colors (just withing Gunnar and there are dozens of good frame builders out there) custom is more rare than it once was. That said, the #1 request among custom frames is level top tube. A distant second is some ditzy to weird braze on. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

The local electronic types favor sandals, bare feet, various "athletic" shoes, and ecologically correct, fair trade, and sustainable shoes. For special occasions, conventional dress shoes or western wear boots. The construction boots are useful because they work in many environments (rain, mud, dirt, sand, etc) and different applications (ride, walk, climb, slog, trudge, etc) where several different types of shoes might otherwise be required. Among the local electronic and non-electronic types, I'm probably the only one who wears steel toe work boots on a regular basis. I'll spare you my rationalizations as to why I prefer such boots for everyday wear. Of course, I have other shoes available, but prefer the construction boots: http://www.learnbydestroying.com/jeffl/pics/drivel/slides/shoes.html After I took the photo, I found another 10 pairs. My goodness, all those shoes! You must be a wealthy man. But I count 15 pairs and one lonely sandal. -- cheers, John B. |

Fortunately, you can still buy bicycles with horizontal top tubes, it's just more difficult. Bikesdirect still has some. I think head tubes (and stack heights) have grown as cyclists have gotten older and less flexible. It's the H2 geometry for the Treks and the more relaxed SuperSix. Compare the CAAD 12 geometry (which was the same for the old SuperSix -- both have level TTs) https://tinyurl.com/s42zlmn with the new SuperSix EVO. https://tinyurl.com/whaohzw It's odd. I rode a 63cm SuperSix, and with the new semi-compact frame, I would fall between the 60cm and the 62cm based on TT /front-center and stack height. Follow the numbers for the the two 60cm frames -- the new frame is more relaxed by a fraction of a degree at the ST and HT and just bigger -- except in the seat tube. More trail. I assume the new bike has a more planted feel. I liked the feel of the old bike and didn't think it needed any planting. -- Jay Beattie. |

I left out that I think it makes it easier for manufacturers to supply fewer frame sizes. Saddle too low? Install a 400mm seat post.

My question is what do these measurement programs exactly do? Are there people that close a bike only based on these measurements? Lou Lou, if its a compact, buy a "medium." Done. 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. 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. 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 Really? And just how are modern bikes fitted better? Do your feet reach the pedals better? Do your hands reach the handlebars better? Never said that. Chosing a bike frame by just stand over height doesn't work anymore with sloping top tubes and handlebars that come in different shapes (drop and reach). But tell us how far back your memories reach. Brooks, for example made various models of bicycle seats in 1880 -- You are playing silly again. Well, you said that, " I remembered that time, where all frames had horizontal top tubes, only 2 saddles and handlebars to choose from". I was amazed that you could be that old and asked you how far back your memories went. Certainly if you could remember back when there were only two bicycle seats to choose from it must have been Before Brooks (for example) started selling more than one model of seat. So who's being silly? You for exaggerations to bolster your arguments? Or me for questioning your exaggerations? -- cheers, John B. John you started to ridicule todays bike fitting by stating that the stand over height method and raising/lowering the saddle and handlebar still works for you. Bike fitting today and the past is all about getting your butt, feet and hands on the right position relative to each other while riding your bike depending on: - preference, - riding style, - your physical condition/ability, - body proportions. Today there is a lot more choices in handlebar drop/reach, frame geometries and saddles then there were in the past. They all determine were your butt, hands and feet end up giving a particular frame. A simple test if your nutts don't hit the top tube and the lower/raise a handlebar and saddle would be a not so smart method to choose a frame size/bike. Lou I originally said, "It used to be much simpler" and it really was. And "fitting" a bike as I described it accomplishes everything that your multi hundred dollar "fittings" do. I assume that you did notice my last caveat, "then ride the bike and make any more changes". But perhaps you are correct and modern day man needs to have his bike "fitted". It apparently is a recent necessity as I don't believe that Eddy Marckx ever had a bike fitting, and he won 11 Grand Tours and more than 500 bike races. For that matter Frank (another old guy) has never mentioned a bike fitting and he has ridden across the U.S. and in innumerable foreign places, or Jay the intrepid (semi old) who rides to work come rain or come shine, who has never mentioned a fitting, or Terrible Tom (yet another oldie) who spends his days climbing mountains. Strange isn't it that none of these old geezers has ever mentioned whacking out nearly 300 dollars to have their arse fitted to a bicycle and yet they ride/have ridden a substantial number of miles/kilometers. While neither Eddy, nor I, nor (probably) Jay ever paid for a bike fit, I suspect that Eddy was supplied with any frame, component or adjustment that might make him a tiny bit faster or more comfortable. I remember reading that he had serious troubles with saddle sores. (And BTW, I really don't think I belong in the same category of either Eddy or Jay.) Over the decades, I did make adjustments to my bike fit. My handlebars rose by at least an inch, and on one bike they were brought closer to me via a shorter stem. It's easy to explain that by lesser flexibility, although I'm still quite flexible. (I can still mount our tandem by kicking my leg forward over the handlebars plus handlebar bag.) My saddle height actually went up a bit over the decades. I don't really know why. But pay for bike fit? No, I've never done that. -- - Frank Krygowski |
