I read Dave Moulton's blog from time to time and recently read a couple of his posts about bicycle fit. He recommends a seat adjustment using the distance from the elbow to the tips of the finger between the nose of the saddle and the handle bars. I tried it on my bikes and Goodness! That's just how my bikes are set up. (which of course proves he is right :-) He also wrote about "women's bikes" and he argues that the real difference between men and women (regarding bicycling) is that the women are smaller and require a smaller bicycle, and, he recommends slightly different angles due to the height difference. I don't necessarily agree with everything that he writes but he did build a lot of bikes and, as far as I can tell, was well respected in the trade and I would guess that the majority of his customers were satisfied with how his bikes fit. I even remember articles about how to tape the handle bars - this was in the days of thin bar wrapping - and some folks even recommended a layer of "air conditioning pipe insulation" applied to the bars before wrapping with the tape. I think what's happened there is that people have spotted all those tips as being economic opportunities. "Heck, if people are using pipe insulation for that, we can buy it in bulk, cut it to size, package it and sell it. We'll get rich!" Nope, they just incorporated foam in the bar tape and all the old thin stuff disappeared. And, I might note, I was browsing through the tape offerings at one shop the other day and came across some tape priced at 1,500 baht a set. About US$42.... I didn't buy it :-) Now all I read is "Ohhhh, that bike is Soooo stiff", and I even saw one entitled "Ride without looking like a Rookie" and another "How to enjoy a solo ride". Not to mention "Get great looking legs!" and articles on just the right outfit to wear when you ride to the coffee shop. $150 bicycle blue jeans! Yup. I've read a couple of articles about how much better shaved legs are. Nobody can quantify exactly why they are better but regardless, they ARE. BTW, a variation on the theme: My wife gets the Terry Bicycles catalog. Georgena Terry was one of the earliest proponents of bikes designed to better fit women riders. (Our daughter rides a Terry bike.) But the catalog has devolved into a clothing store. There's no evidence that they still bother selling bikes. One of the basic facts of life is "chase the almighty dollar" :-) -- cheers, John B. |

"Cervélo believes that women-specific bikes aren’t necessary because, contrary to what consumers are told, men and women’s leg and torso proportions aren’t different—the only difference is between short and tall people.

There does seem to be some justification for women's track bikes to have a bit slacker seat tube angle which seems to make the bike "fit" a little better. But that is for a bike that is essentially ridden in the drops, not a normal road bike. http://cyclingtips.com/2015/05/women...et-part-three/ Nonetheless, there are a lot of women-specific-designs out there, and women have become the new bicycle marketing frontier.

Now all I read is "Ohhhh, that bike is Soooo stiff", and I even saw one entitled "Ride without looking like a Rookie" and another "How to enjoy a solo ride". Yeah, or stories about the latest and greatest gizmos that cost a fortune. I quit reading bike magazines a long time ago. What I am much more interested in is endurance testing of tires and other stuff like they regularly present in car magazines. But it doesn't happen, so why buy those magazines? Are bicycles now so standardized that we now don't have to be told how to adjust handle bars? We still have to adjust. Serious riders make sure they get the correct frame size. When I bought my new MTB I rode it for a while after the LBS had adjusted things upon delivery. I read up on best positioning for the various riding styles, there's plenty of information. Just not in magazines anymore because it's all online now. Per these instructions I shortened my handlebar in 10mm increments because I was brushing stuff too often on trails. Until it felt just right. Then I tried stem lengths and found that 80mm suited me much better than the stock 120mm. Slightly steeper angle as well. Now the "cockpit" fits like a glove. The usual "rule of thumb" for road bikes is the handle bars are the width of your shoulders, which means that your arms stick straight out in front. I've always assumed that this was a good until I bought a new(old) bike and riding it felt fine. Eventually I measured the handle bars, Goodness! They were 3 cm wider than "normal" and I had never noticed it :-) ... Or does the LBS now do it for us? A good one will. But just like with the adjustment of a partial at the dentist there is a finite amount of time the LBS will be willing to invest on the courtesy side (as in free). If you offer to pay he'll surely adjust your bike as often as you want to. I even came across an article "Race Back in Time at L'Eroica" a story about riding a steel frame bicycle that had toe clips and down tube shifters while wearing a wool jersey. (I think that old age has crept up behind me when I wasn't looking :-) If it's any comfort I ride a circa 1982 steel frame road bike, down tube shifters, changed from 2*6 to 2*7 after I crunched the freehub. I also gave it a 11-32T cassette which is the maximum the old Shimano 600 derailer was willing to stomach. 52/42 up front. Still not so ideal for some of the hills here but suits me well. I find that the terrain seems to be the deciding factor. In Bangkok, essentially flat, I find down tube shifters to be just the thing and make maybe two or three gear changes a ride. In Phuket, which is essentially a mountain sticking out of the water I use a 3 x 10 setup and on most days will use nearly all the gears. The bike was custom made for me so back then was expensive. Immediately after delivery I added lighting and a sturdy luggage rack. Meantime I removed the toe clip pedals and replaced them with ... gasp ... MTB pedals. Last year I added small panniers (Nashbar Daytrekker). Those kinds of changes and my unorthodox clothing causes some in the Lycra-crowd to look down on me but I don't care. Do I feel old now? Nah! -- cheers, John B. |

Per John B.:
I read Dave Moulton's blog from time to time and recently read a couple of his posts about bicycle fit. He recommends a seat adjustment using the distance from the elbow to the tips of the finger between the nose of the saddle and the handle bars. So far, I have not heard an argument against my own seat-distance setting: - Riding on the saddle, upshift until you are pedaling with your butt floating an inch or so above the saddle. - Peddle like that for a minute or so. - Downshift until your butt settles back on the saddle. If your sit bones are not centered in the usable portion of the saddle, move it fore or aft and repeat until they are. I have found that handlebar extension does not affect where my sit bones rest on the saddle. My bars allow me to shift my grip 7+ inches fore and aft - and the outcome of the floating-butt test above seems to remain the same with my grip all the way forward or all the way aft. And if there *is* a diff, it is no more than a quarter of an inch - arrived at by setting the saddle so my sit bones are on the rear edge rivets of the saddle so that I can feel any diff. I think there is a psychological/marketing factor in at least some of the recommended settings/sizes: people have a built-in desire for hard-and-fast rules and making some up helps sell bikes. I remember surfing in the early sixties: the board makers felt constrained to issue precise recommendations on board length vs the surfer's height..... and then mini-boards came along.... -- Pete Cresswell |

You are trying to destroy the American Dream. A fitter that was fast on his feet might be able to work in two "fittings" in the morning and two in the afternoon. A Grand a day. Shoot, only have to work one day a week :-) On a ride this week, a friend described the results of a professional bike fit session, albeit a much less expensive one. As I understood it, the changes were a centimeter here, a centimeter there, and a tremendous increase in comfort. Personally, I doubt that I can feel those centimeters of difference. For me, the only one that's really important is the height of the seat, but even that one is effectively changed when I ride using a different pair of shoes; and for rides under (say) 30 miles, I don't bother to re-adjust it. And regarding the forward reach, I just measured it on the four bikes I ride most. They vary by a full inch. Admittedly, I'm not much of a connoisseur. And I don't doubt the value of a proper fit when getting a brand new bike. But I wonder if the value of expensive fine-tuning fit sessions might be matched by some ceremony involving feathers, bones and rattles. -- - Frank Krygowski |

By the time I'd have changed all that plus brifters and stuff I might as well buy a whole new bike. And then my wife would want me to get rid of this one which I can't do (yet). [...] -- Regards, Joerg http://www.analogconsultants.com/ Shoulder width or a bit wider was needed when bicyclists were riding bicycles with short cockpits and their knees came up between their elbows when the bicyclist was riding in the drops. I guess my frame is long enough because I am over 6' tall and ride in the drops occasionally. Max 5% of the time though, getting too old in my back for more. There is never interference. However, the narrow handle bar has another drawback I just found out. I can't mount the new MP3 player (with speaker) on there or I'd take away too much grip area up top. So unless I switch to a wider bar I'll have to build some sort of steerer tube mount for that. Bicycles have surprisingly little options when it comes to mounting additional gizmos. On long boring uphill slogs that little MP3 player is nice. -- Regards, Joerg http://www.analogconsultants.com/ Pockets are very useful for putting MP3 players in. My T-shirts don't have pockets and it wouldn't work anyhow because it's this kind, with speaker: http://myivation.com/index.php/ivati...h-speaker.html It is about the size of the cardboard drum inside a toilet paper roll and has remarkably good sound. I do not like to wear any plugs in my ears and AFAIK that would also be illegal here. The rubber strap that comes with it is too flimsy. -- Regards, Joerg http://www.analogconsultants.com/ |
