In almost every case replacing front suspension parts to eliminate excessive play cured the problem. I wonder how much wheel shimmy with bicycles is due to loose wheel or head bearings. Shimmy can be very weird, very hard to diagnose. My motorcycle is a 1972 BMW R75/5, the short wheelbase version (nicknamed SWB). In 1973 BMW lengthened the wheelbase, adding maybe an inch to the swing arm. The rumor is that was done to cure the tendency to get a "tank slapper" - a front end shimmy so violent the handlebars alternately hit either side of the tank. There is dispute over the likelihood of this shimmy. I've never experienced it, and certainly don't want to. It seems fork mounted front fairings increase the chances (although I used to run one), as do heavy loads mounted high on a rack protruding behind the seat (which I've never used). One guy with a famous BMW website (similar to Sheldon Brown's, in a way) claims the only cure is super precise alignment of the two fork tubes, to totally eliminate all front fork stiction; and that any SWB owner is foolish to skip this tedious procedure. Others say they've never bothered with that, have ridden hundreds of thousands of miles and had no problems. OTOH, as Andrew knows, I once owned a 1966 Corvair Corsa. In 1973 I sold it cheap because it had developed an intermittent violent shimmy at moderate speeds (maybe 50 mph) that neither I nor a couple suspension shops were able to diagnose. I've had that symptom (in a not-Corvair) which was cured by replacement of the damaged spindles. It was both scary and ate up a set of front tires pronto. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

This despite I am 6'4" tall and this would theoretically aggravate shimmy on a bicycle and front end stability especially on racing motorcycles and especially on drag racers which had extended frames likelier to have misalignment if less dangerous frame/fork interactions. I would think perhaps motorcycle problems would be especially sensitive to frame misalignment which goes back to the jig we were discussing earlier or what you were trying to change the subject to whatever you believe it should be called instead of the point of the discussion. By the way, most Corvair shimmy problems were due to the tire tread and locally they would sell the owners a specific brand of tire that would end the shimmy. |

My wife and I had entirely different pedaling styles and speeds so we quite rapidly sold our tandem off. Because of this difference we did experience quite a bit of frame flex but never any shimmy. As I was saying before, one of the people I ride with has a Cannondale and he cannot coast anything like my bikes and slows quite rapidly. So finally I looked at his bike from behind and it was quite obvious that the heliarc caused the two rear vertical dropouts to be somewhat misaligned. This forces the bike to steer the front wheel slightly sideways and is the source of this extra drag that causes the rapid reduction in coasting speed. I sold this guy an aluminum Colnago that doesn't have this problem but he prefers his Cannondale for our rather slow Saturday rides. |

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. Thanks for that bit of information Ted. That gives me the distinct impression that perhaps I should buy a "sport" rather than full race model. Gunnar Sport is what race bikes were in 1970. 500 length caliper and clearance for 28 with mudguards or 32mm without. Race geometry is 25mm max, 450 caliper. Waterfords (despite 'suggested geometries') are each drawn from scratch, custom to rider requirements including material and tube gauge. There are no other quality differences between the two lines- materials, welders, paint all exactly the same. Waterfords can be optionally lugged silver braze, Gunnars are all TIG. I bought my Waterford frame back in 1998 I think. 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. Sounds like exactly the bike (and components) I bought, mine was in red. I bought it through my LBS; at the time it was a great shop. (Hodson's Bay, owned and operated by Lynn Hodson) My Waterford 1200 is a red/burgundy color. Candy apple red may have been the official Waterford color. Absolutely BEAUTIFUL. I'll let others argue about which frame material is the bestest of the best for making a bike frame. Titanium, carbon, aluminum, steel, bamboo, etc. But for pure aesthetics, nothing can touch a finely painted lugged steel frame and matching fork.. ...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. Yep, that's my recollection too. I bought the standard 60 cm size with the top tube shortened by 1 cm as I mentioned upthread. There was a small upcharge for that modest customization. As I recall, we (the LBS owner and I) settled on that configuration because the 58 seemed slightly too small and the 60 perhaps a bit generous--figuring if it turned out to be too short, we could make it up with a somewhat longer stem. -- Ted Heise West Lafayette, IN, USA |
