I on the other hand have had no luck adjusting a headset to eliminate shimmy. I think you should remove the handlebar bag and see if the shimmy is still there. If it goes away, then you will at least know the cause. Jobst Brandt has said some interesting things about shimmy that you might want to read: http://www.sheldonbrown.com/brandt/shimmy.html http://yarchive.net/bike/shimmy.html > - The bike creaks constantly; there is some creaking when coasting, but I > cannot associate it with anything in particular.

I usually start by removing everything that is not bike or wheels-- including water bottle cages and seat bags. To eliminate the saddle, stand on the pedals. To eliminate the pedals, sit on the saddle and lift your feet off the pedals. Then on to the wheels. I've had hubs dry out and make sounds while coasting that sounded like creaking. Also, try squeezing pairs of spokes to see if any of them are loose or make creaking noises. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
