DuraAce 10 spd chains 7801 vs 7900

Tangled Tango said:
Can anyone tell me the difference between Dura Ace´s 10spd 7800 and the newer 10spd 7900?

Also can the 7900 chain be used with the 7800 components?

Thanks, ew

I say use the 7800 chain. Cheaper, not directional. BUT yes you can use a 7900 chain with 7800 and a 7800 wit 7900 components but front shifting suffers on Di2 with a 7800 chain.

Best idea is use a 105 level 10s chain. less shiny but functions/wears the same as bigger buck chains. it is a consumable, afterall.

Here's a little secret to save you some money on chains: The 105, Ultegra, and Dura Ace chains are all identical except for the plating. Dura Ace has both inner and outer links nickel plated, while Ultegra only has the outer links plated and the 105 has no nickel plating at all. Functionally they are the same, you'll never be able to tell the difference in a blind test, so skip the $50 DA bling for winter training.

I should clarify that this only applies to the 7800/6600/5600 series of chains, the 7900/6700/5600 (no new 105 yet) do have some differences beyond just the finish.
