Some AMs are still being made. Not heard of an AM8 though.

The factory was selling neat little chain catchers for AMs that behaved similarly to front derailleurs.

Thanks Dave
A device to keep the chain on sounds like a good idea! I’m still keen to confirm the spec of chain required though…

Without looking at it, it is difficult to diagnose the problem. In general, any 8sp chain will behave similarly. Long teeth on the chainring are noticeably better for retaining the chain than the trimmed and shaped chainrings designed for faster shifting.

yes I have the same problem with my tsr 30 the stronglight crank looks a right mess now,it does not seem to make much difference how much I adjust the front ,the chain still comes of every now and then.
