Seems unlikely, but who knows. -- Ted Heise West Lafayette, IN, USA I really wouldn't want to speculate on the causes of shimmy or for that matter to have my livelihood depend on tracking it down. I have in mind that when (by extension from Chalo recommending Utopia-velo's Kranich to me) I was shopping the the German baukasten to see what was available, I came across a case of shimmy down an Alpine mountain (!) in the other German top-dog, Patria. It was apparently caused by fitting Big Apples and did them a lot of commercial harm before it was rectified. Now, despite what you may have heard about the hemi-heads I developed when I was an auto racer, my specialty was actually suspensions, but for the life of me I could not see precisely how a Big Apple -- a truly superior tyre -- could cause a shimmy on a straight, long wheelbase bike with plenty of its own damping (as possessed by every proper touring bike not designed by some idiot burdened with a roadie legacy). "Who knows?" Indeed. . Andre Jute PS I was about to say that Jobst Brandt mentioned the possibility of an harmonic progression punishing a designer who had done nothing wrong, when my eye fell on Andrew Muzi' s note to that effect, complete with specific reference. I would add that I enjoyed my time designing ultra-fidelity loudspeaker enclosures quite as much as working on suspensions, and for the same reason, that beyond the tricky non-linearics lies art. Professionally Jobst was pretty much an expert but personally he would delve into the realm of asshat. |

Late 1997 or early 1998. I put 1998 Campagnolo Chorus group on it. The first year with the new round top on the levers. I bought my 1200 model (Reynolds 753, silver brazed short point lugs) through an internet bike dealer who got frames and bikes from all over and resold them. I did not buy directly from Waterford. My 58cm frame is the standard frame geometry that Waterford has/had on its website. So back then Waterford did make standard size frames, not just custom. I believe Waterford always offered custom sizing on its frames for free or minimal upcharge if you did not want the standard size frame. Fortunately for me their 58cm standard sizing is the exact same custom size I would order if I was getting a custom frame. I'd just hand the Waterford 58cm standard frame sizes to the custom builder and say build it exactly this size. |

Schwinn tried to market some really top flight steel bikes in the PDG Paramount group but I think that happened to be at the time when bicycling was not very popular and it couldn't support itself. That was Richard's brother who is absolutely not pert o Waterford Pre4cison Cycles. I've been told Waterford was somewhat of a continuance of the Paramount lineage, but perhaps that was not correct. In 1997 I bought a nice Waterford and rode it for many years. It was a very nice bike, but nearly killed me with a bad case of shimmy coming down Fremont Pass one year on RtR. When they built the frame, I had them shorten the stock top tube dimension by a cm, and have always wondered of that was a factor. Seems unlikely, but who knows. It's an harmonic phenomenon which, as Jobst noted often, can occur when frame is straight and headset is adjusted properly. See his notes at #8 H5 he http://www.faqs.org/faqs/bicycles-faq/part4/ I was going to say that a shorter top tube should reduce the tendency to shimmy, other things being equal. Less length = more stiffness, so a higher natural frequency. Then I saw that Jobst implied the same thing on that site: "The longer the frame and the higher the saddle, the greater the tendency to shimmy, other things being equal." Jan Heine claims roller bearing headsets reduce shimmy. I can't say if that's true. I have a roller bearing headset only on my Cannondale touring bike, but that bike is so rigid that shimmy is probably impossible. Except, that is, one time I had a heavy and loose load in a very flexible handlebar bag. The bag shimmied and took the bike with it. My current bag is very rigid and probably adds enough inertia to the steering to lessen any shimmy tendencies even further. -- - Frank Krygowski When I was a paperboy I used a bicycle with a step through frame because it was easy to get off and on the bike (we don't throw papers on the peoples lawn). With a lot of newspapers in the panniers I could introduce a shimmy every time by riding no hands and wack my handlebars. I did that for fun to see how long I would dare riding no hands with a shimmy. Lou |
