If you take them off and put them back on with the slot misaligned, they may click more, but as I can't see them, I wouldn't know. I'll be glad to sell or trade the set, they are grey anodized with white accents, off a Centurion LeMans RS.

I used them with a 1/2 x 13/32 chain in friction, no problem. If you index 6 speeds, the same chain would work. If you index more, you'd be better off with a 7 or 8 speed chain.
