    Replacing chain, difference between dura ace cn-7900 and cn-7901?

    Hey ppl up for replacing the chain and can get a real good deal on both, so just wondering, what's the major difference between the two chains? Thx!

    I think in Ultegra chains the 01 is recommended for triple chainrings. Check the Shimano site to be sure.

    Edit: Or I could be totally wrong! Just looked at a couple of things that said the 01 chains were "double chainring only."

    Ha thx, for the input, ya I think they are both 10spd chains, just not really sure what's the diff, do they both perform the same or are they night and day?

    the 7900 has the quick link. Shimano dropped it PDQ over technical issues. The 7901 uses the traditional push pin

    Thx for the info, guess I'm safer with the 7901 then?
