Hello,

I’ve got a Dura-Ace CS7900 10sp cassette 11-25 and some FSA Vision aero chainrings on my TT bike, I’m just upgrading from some 9sp stuff which has now been moved onto one of the other bikes.
I’ve not really had much to do with 10s before, do I need one of those silly directional chains or can I just fit a normal DA one?

Cheers,
Andy H

10sp DA chains are directional-all 10sp Shimano chains are (writing only on one side)
KMC/Wippermann/Sram will all work fine so take your pick

Thanks GW, used SRAM ones before so might have a look for one of those. I’m all of a cafuddle regarding compatibility nowadays

Ordered a SRAM PC1091
Cheers

I’ve currently got four bikes running 10speed Shimano & chain wise have:
1x Wippermann Black Edi
2x Shimano SLX/105
1x Sram 1051

Only one I can genuinely tell is the Wipperman, as it’s nowhere near as smooth as the others-feels like it’s grinding away constantly even with a new groupset.
You won’t have any problems with the Sram.
