Hi all. Well my new Bike Friday New World Tourist came about 2 days ago. What a toy! I have the setup with the three chainrings in the front and 9 gears in the back. One issue stood out right away for me. Every time I shift into gear 6 or above (with gear 6 exhibiting the issue in the most obvious way) I "feel" a light discernable thud-thud or maybe a clunk-clunk (not in tune with each pedal rotation but about two per rotation and not seemingly symetrical). I can't see what is causing it when I study the rear setup on my bike stand (or the front setup for that matter). This thud thud (not loud, but more felt) is present regardless of which of the three front chainrings I am in. Maybe the cassette just needs to wear in, but I never have felt something like this on any other new bike I've had. My LBS is closed for a few days and I thought I'd have him look at it, but thought I'd say hi and ask all of you as well.
