Middle ring for a M569 chainset

Postby barbelfisher » 7 Mar 2012, 7:35pm

Desperately seeking chain rings for a 1997 M569 LX chainset. I have managed to source a new outer ring from the US but still need the inner ring. Product no 1BD 9832 32 tooth 4 arm ring.

Lots of people do them: Middleburn, Black Spire, RaceFace for starters.

Avoid the Shimano ones, they are made of silver cheese they are so soft and wear rapidly. Try Wiggle or Chain Reaction if you want to buy on the internet.

If you have bought a new big ring already then fair enough, but you can buy quite a nice new chainset for the price of two chainrings.

cheers
