Hoolander...Urbestfriend says "Thanks for this tip." It was well into the list
and addresses the same exact issue. Today I rode the whole 11 miles from work
and didn't have one episode. (Didn't stop but once or twice.) Brings me to the
conclusion that more active riding, stops, starts, etc. will cause the noise.
Currently...I am comparing the parts list for both tis bike and my Grandvista.
Many of the same parts seem to be used on either model. It's always a good
investment to have common replaceable parts in your stock.
