just wondering of other peoples experience of using a sram chain with shimano chainrings.
I have been using a PC-49 chain and Deore cranks with the upgraded middle ring to the alloy LX/XT quality. At present I have gone through chainrings as fast as chains. (approx 1000km). The last chain was just showing signs of wear and the cassette is still ok with the new chain, but the chainring had mushroomed the front of the teeth (especially where the shifting ramps make the front of the tooth very thin) and had visible elongation of the 'valley' between teeth. I know of others that have got ~4 years out of chainrings, and the only difference is that I use the sram chain.
I am currently trying a truvative middle ring to see if that makes a difference.
