Fork Offset & Steering Characteristics
I recently bought an 83 Trek 560 and was disappointed with the twitchy nature to the steering at speed. I posted a thread in the C&V Forum about it here: http://www.bikeforums.net/showthread...ed-83-Trek-560
I have read comments about some bikes not feeling stable at higher speeds, but I have never read why this would be. I would consider myself an experienced rider of mostly lugged steel road bikes, but I have never owned a bike with steering this sensitive. I once owned a high end Italian bike that road as if it was on a rail, this is the opposite of that. I would not consider riding this bike hands-free unless on a very smooth surface at slow speed.
I first thought that it may have to do with the headset as it was badly brinelled but not loose. I replaced it with little to no effect on the handling. I started reading about fork offset and fork trail. Then I remembered that the bikes I had owned in the past had a fairly straight fork. This one has somewhat more of a curve to it. Iíve considered that the fork may be damaged in some way, it there is no obvious or unusual misalignment that I can tell.
Has anyone had this experience or know why one bike could track rock solid, while others ride erratically?
