Rene:
I had Tom build a fork for my 58 cm Atlantis, 40 mm trail. The reason was a vague wandering of the front end while climbing at low speed & this seems a common complaint. I always have an Acorn Boxy Rando bag on the front, with at least a few pounds of maps, pump, misc junk, etc. Was this wandering sensation your reason for changing forks?
Also, it's been suggested that lower trail may contribute to shimmy. Even with the stock fork, my Atlantis has always had a shimmy when rear loaded. For instance, even with the front bag and only 2 panniers in back (nothing on the top of the rack) I've experienced shimmy. I cannot be sure but it may happen more frequently now that I've changed forks. Have you noticed any shimmy problems? With either bike?
Note the shimmy has never happened with either a front only load (2 panniers on low riders) or a balanced, 4 bag load. I have one of IRD's roller bearing headsets on its way. Jan Heine suggests roller bearing headsets have more friction and have been helpful in reducing shimmy. I figure it's worth a shot.
Look forward to hearing your thoughts.
