I'm not sure of the term but often when I go into the granny sometimes the chain jumps off the front, I'll be padaling and suddenly, nuthin, spinning in air. My lbs says there's a deedly-wob they can put that "catches" the chain so that doesn't happen. We've both got top of the line parts...should work perfectly, eh?

I'll try the burning sage n' pictures of mario thing, can't hurt, cheaper too. ;-)

Or train so don't need the granny? Nah...

g'night.
