Thanks Rowan. Good to hear they'll work on the Shimano jobbies. So they don't cause any trouble with changing gear or wear on the sprockets? Just as an asside, the LBS dude here the other day tried to tell me that shimano chains came in one for 6 to 8 speed, and another for 9-10 speed. I thought 10 speed had their own?

Aww Dave. It was much simpler when we were in the roadie forum. I could actually ask the rare bike question without feeling guilty.
