BTW, a Peloton ad recently got the internet's ire up. https://www.thecut.com/2019/12/pelot...icized-ad.html All that tells you, Franki-boy, is that their marketing department and advertising agency suffered an explosion of group think, with predictable results, magnified by the constant malice of little people like you whose malice is empowered by social media on their phones. It tells the rest of us that you're so weak-minded that, despite your claims to be a "spokesman for bicycles", you gloat about damage done to a corporation that might well in time have put a few people on bicycles. It also tells us you're so railroad-minded that you cannot see that these Peloton people were creating an avenue for proselytising potential cyclists. Once more everyone runs into the pot-iron barriers around what little there is of your mind. Those pot-iron barriers aren't much good if they leak malice on the scale visible in this post of yours.

My question is what do these measurement programs exactly do? Are there people that close a bike only based on these measurements? The last bike I bought (gravel) was advertised with a chart that was scaled to leg length. According to my leg length I should have chosen an XL frame, but I reviewed the frame angles and geometry against my custom road racing bike, and decided on a L size frame. The XL would have had my hands too high. Even so, with the L frame I have the head stem all the way down, and I used a longer stem than the supplied one of course, and I used a longer seat post too. I also dislike the sloping top tube "compact" design, for the simple reasons that; a) longer frame tubes would probably weigh less than a long seat post, and a longer seat post likely stresses the frame more. b) the sloping top tube is very difficult to sit on while you're stopped somewhere to admire the view and eat a banana. c) the area in the triangle is reduced which restricts that available to carry water bottles or frame bags and stuff, if you so desire. While bucking current fashion, you are not alone. The #1 item in custom orders is 'level top tube'. I wonder why this is the #1 request. Is it people who are invested in using their old Silca frame pumps? My custom order would be a Gruber Assist with the hidden Di2 button. -- Jay Beattie. |

Mythology Jay. Cycling is rife with it and you know that. A fellow I know went to an LBS where the fitter had "a bigger rep than the guy who hands you your coffee at the machine". He thought *he* was being fitted but after a lot of shoving and pushing, the clerk said, outraged, "You don't fit any of our bikes!" ***** The customer complained that his new suit didn't fit. 'The sleeves are too short,' he said to the tailor. 'Yes sir,' said the tailor, 'but if you hold your arm just so, at an angle as if you're drinking tea with your auntie, it will show just the right amount of cuff.' The customer tried it. The tailor was right! 'But what about the other sleeve? It is definitely too short.' 'Just lower your shoulder, sir. Yes, yes, a little more. Put your foot out so you can lower your shoulder a little more still. Bend your knee. Yes, that's it. See how beautifully your suitcoat now fits?' The customer had to admit the tailor was right. 'Wow. But now the leg of the pants is all twisted around.' 'That's easily fixed,' said the tailor. 'Just point your other toe westward, sir, and look over your shoulder to where I am holding up the hand mirror. See? Doesn't that fit beautifully?' 'Yes,' the customer said doubtfully, 'but-' 'Now would sir like to wear his brilliant new suit or shall we wrap it?' The customer was too intimidated to argue. He walked out into the street in his new suit, his arm crooked as if he were drinking tea, his other shoulder well down over a bent knee with his foot out to the side, his other foot pointing westwards, his head twisted back between hunched shoulders as if complaining to God about a cruel fate. Behind him he heard a boy say to his father. 'Oh, Daddy, look at the poor twisted cripple.' 'Hush,' the father said. 'Be grateful the poor man found such a brilliant tailor.' From http://www.audio-talk.co.uk/fiultra/...dre%20Jute.htm **** Andre Jute Euphonics I have bikes that fit that are from 58 to 62 cm. As a sports rider the main thing to obtain is control. I can descend FASTER on the round tube, high sitting Basso at 62 cm than I can with the aerodynamic Colnago. So I just say that I'm not a Lance Armstrong - I'm much closer to a Neal Armstrong. And leave it at that. |

What does it even mean that your bikes fit you to within 1mm? 1mm of what? 1mm of my desired posture on the bike, of course. What else? 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. I could ask the same kind of cantankerous question as your question: What does it even mean that your bikes fit you to within 1mm? 1mm of what? say, "What does it even mean that your fit changes? From what?" But I won't. I'll give you the benefit of the doubt and assume you know what you're talking about. If you do, you've just made my point for me. If you don't, I already have a knowledgeable source of advice, thanks all the same. 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, The better baukast (a German custom bike house, more precisely semi-custom as some of them are pretty big, and there are some German full-custom makers who'll build you a custom frame from scratch) has a philosophy and a set of frames to match it, and many sets of components approved by being tested to destruction, in the case of my chosen baukast in many cases designed for them by first-class German, Dutch and Belgian component makers. First you ascertain that the philosophy of the main man at the baukast fits you, then you check that one of their bike sizes fits you, then they change components until it fits you perfectly. At my chosen baukast, for instance, they consider tall seatposts bad engineering, as do I. So they want you to sit comfortably with your feet on the pedals without adjusting the designed-in seat height more than fractionally. And so on, point for point matching my outlook/prejudices, desires. Next thing I looked for is that all their bikes are truly scaled because they ordered custom tubes from Columbus, none of those Gunnar abortions of very tall bikes with very short chain stays because that's what the manufacturer had in stock. So their bikes have long wheelbases in relation to size, and that too is good, because I like to know how a bike will handle at the limit before I buy it, and a long wheelbase is half the battle for predictable handling. Etc, etc, a lot of stuff you won't understand, or want to hear, because you find me "tedious". 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? I own two other bikes that serve the same purpose, from Gazelle and Trek, people with very clued-in designers and marketing departments. My Utopia is fundamentally different in almost every respect, and does a great many things better than they do. But, since you drive a Subaru, and buy your bikes over the counter, you won't understand how these many advantages, some of them objectively small to the uninitiated, can add up to permanent satisfaction. In fact, I think it very likely that you will entirely miss the many advantages and be more concerned that the sum total of the prejudices of my bike maker doesn't add up to a bike that looks like every other bike. I couldn't care less about other people's opinion, but I understand those who'd rather blend with the moo-moo herd. Your Utopia is a Byzantine mixte with a f****** motor. Why would you even need a custom fit? https://i.pinimg.com/originals/43/8b...9987ece1ca.jpg My wife had a comfort bike like that and whenever I wanted to use it to go to the store, I would just raise the saddle. It had a QR post clamp. Very convenient. -- Jay Beattie. |

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. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Is it people who are invested in using their old Silca frame pumps? I suspect it's just aesthetics. And if a person likes it, why not? A custom bike should accommodate one's quirks. Related: Aesthetically, I'm bothered by the look of modern forks. Carbon fiber ones look chunky and clunky. But even steel forks often don't look graceful to me. The classic look seems prettiest: a tapered fork blade that starts in line with the steering axis then bends forward to meet the front axle. Even the straight steel fork blades that angle forward from the fork crown look awkward to me. There was a spare logic to the design of classic bicycle tubes. I know CF and disc brakes have changed the design requirements, but I think some custom makers deviate from the former norm just to be "modern." And before people attack me even more, this preference isn't related to yearning for a past era. I wouldn't have liked a curly stay Hetchins either. -- - Frank Krygowski |

At least one company, "Thorn Cycles" used to mention that a bike had "toe overlap" in their catalog. Generally more common in high performance bikes. Yep, anything with a steep head tube angle and a short wheelbase will have the problem. I managed to make things worse by routinely wearing steel toe construction boots while riding. It became an issue after several low speed crashes while cornering. On my Trek 1400, I once measured the angle on the front wheel where my toe might overlap the front wheel. Methinks it was a fairly large 30 degrees, with the forward motion of my heel stopped by the pedal. I just checked my Gary Fisher Tassajara: http://www.learnbydestroying.com/jeffl/pics/bicycles/slides/Gary-Fisher-Tassajara.html and found about 5 degrees overlap (again with construction boots). I previously tried to use toe clips to reduce the toe interference on my Trek 1400, but couldn't find toe clips that would also work with platform pedals (so that the waffle pattern soles will slide easily). ?? https://www.amazon.com/bicycle-toe-c...ycle+toe+clips I could probably have made something work with custom front fork extensions and disk brakes, which would increase the wheelbase, but didn't think it was worth the effort. Sheldon mentions it and says, " Many, many people ride bicycles with fairly severe overlap with no practical problems" My other bicycles have a longer wheelbase and therefore less of a toe interference problem. I'm not up on "modern" bicycles as all my bikes are "classic" steel frame, level top tube, etc., and they all have toe overlap and I have never found it to be a problem as I can't imagine ever turning the wheel far enough to hit my toe at even walking speeds, Imo it affects commuters more who may often be using high turning angles maneuvering around street furniture, pedestrians, junctions etc. Also, adding mudguards doesn't help :-( I experienced that when I added fenders to my usual bike. Fell down in the road, once, but haven't done that again Also, the shorter one is, the more likely toe overlap, given the usual size wheels. If I start out up a hill than yes, perhaps for the first revolution or so of the crank I will be traveling slowly enough to have too turn the wheel back and forth, far enough to hit my toe, to keep balanced but other than that I have never had a problem. But from your posts you seem to be an electronic sort of guy. Do electronic guys wear hulking great boots? -- cheers, John B. -- |
