Irulan advised "Have you had it checked with one of those do-hickey gizmo thingys?"

you mean the chain...uh...whatchamakalit? not the wrench, the thingamabob that checks if your chain has stretched? are we tech savy or what?

yes, at least my LBS did recently, could have missed it. I thought I was just forgetting that I don't have one lower gear but then it happens when I'm NOT in the lowest available gear, and usualy when I start going uphill.

my bike club is starting to think i throw the chain off to avoid doing hills ;-)
