I agree with John. Maybe a cleaning will do the trick but if not and before you head to ebay, post a pic. I have several Suntour clicky stemies from the dump and I might have what you need for the cost postage or a friendly trade.

+ on the barend shifters, John. I took my first shakedown ride on the Paramount on Wednesday. It is great not to have to reach to that down tube on a 25 inch frame to shift! I picked up another set on ebay last winter and when I retape the bars on the Traveler this winter, barends will be installed.
