This is my bike:

I've been told today that shimano 105 or ultegra gearing will not work properly if I only upgrade the levers and derailleurs to sram etap!! I have to upgrade the crank cassette and chain to also sram.
If this is true I would like some help on choosing the correct chain set please. Currently I'm using 105 50/34 and would like to keep it 50/34 but using sram.
Ide like a link to the correct chainset and cassette if possible please? Much appreciated. Thank you.
Not sure what sram etap is? I run force cranks, rival mechs and shifters and an ultegra casette and chain with no problems.
Why do you want to upgrade a perfectly good groupset on such a new bike ?
If you do change you're chainset you will probably need a new bottom bracket too.
Assuming you run 11 speed Shimano, I can't see any reason why you can't use the eTap shifters and mech with different chainrings, cassette and chain. Max cassette size is 28 for the eTap though.
I use Red 22 on one bike with non-SRAM chainset and rings (Rotor + Praxis Works). No issues.
eTap is great, it's on my best bike - I am using the Red crankset that came on it originally so I've no direct experience of eTap + non-SRAM crankset. I upgraded a perfectly good groupset on a year old bike because a) I wanted to, b) I could and c) the Red 22 bits went to the second best bike.
Quick Edit - this thread says it's fine too: [url= http://www.bikeradar.com/forums/viewtopic.php?t=13043271 ]http://www.bikeradar.com/forums/viewtopic.php?t=13043271[/url]

Because the one I have now ain't the best and I was going to upgrade to ultegra chainset until someone at wiggle told me it wouldn't run with sram etap. But now I know different it's fine.

Thank you mate.
Surely would have been cheaper to buy the bike with Di2 ?
When it finally arrives I'm going to be using SRAM etap HRD with a Sugino chainset. My expectation is that it will work, I have no reason to believe that it won't. All 11 speed cassettes have the same spacing now - herself is running Chorus EPS with an Ultegra cassette - it works perfectly, especially as the cassette is less than half the price of a Chorus one.
