A needle bearing headset seems to help with shimmy but isn't a cure all. I experienced a violent shimmy even with this headset. I was riding downhill and hit a patch of sand on the asphalt. It was a OMG, I sure I'm gonna wreck, experience.
I was lucky and rode out the shimmy. Afterwards I stopped to compose myself and to check the bike out.I was sure something was seriously wrong, but couldn't find anything. While it was happening I thought for sure a tire had blown out, but my tire pressure seemed fine. I tightened the headset a little, counted my blessings, and rode home. The bike I was riding has standard diameter, thin-walled tubing and is optimized for carrying a load up front. My Acorn Boxy Rando bag was carrying about 6lb. I haven't experienced front end shimmy since. Hope I never do. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
