I don't see why it won't. Keep in mind that OEMs are speccing etap on bikes with several different cranks such as FSA and such. I haven't heard of any front shifting issues from it yet on anything. Thankfully as far as 11 speed goes, most everything drivetrain related is spaced the same across the brands.

But will it be optimal? Can't imagine SRAM or Shimano testing to make sure such a combination would work or work well. If you are spending all that money wouldn't you want an optimal solution rather than something that works? Just my gut reaction. It's not a reaction borne of any knowledge of the engineering of the two systems.

My question is why run heavy Dura-ace cranks if not to "complete the group"? Plenty of us use Red cranks and cassette on an otherwise Dura-ace bike because they're lighter than the Shimano parts.

Sram Red GXP crankset + bottom bracket

vs.

Dura-Ace crankset + bottom bracket


Look it up then come back and tell me how heavy Dura-Ace cranks are.

BB30 doesn't count, that's apples to oranges.

My bike right now is equipped with shimano 9000. if I took it off to sell it I probably get six to $700 tops. The upgrade kit for the sram Etap is $13-$1400. The whole groupo is $23-$2600. That's my thinking.
I have riden the DI2 for the last year but feel I like the shifting pattern of the new Sram etap. Both systems are incredible but the frame I want to put it on does not have internal routing.

yes you can, a friend of mine is doing exactly this.
even his shimano brakes will work, albeit not as optimal had they been sram brakes, but they work ok for him.

The reason, so far sram only have 5 arm, 9000 has much better selection of gear ratios,
I have run 53-34 everyone says it will not work, it does..

Sure...it shifts. But it's not great. You're over the capacity of both derailleurs. Not a good thing. Either the chain is too long in small/small or you're really close to ripping the rear derailleur off the bike in big/big.

I left out short cage normal rear mech, but didn't think anyone needed telling not to go to the extremes, small - small, but your right, people do some funny things, anyway, it was just to make the point of 4 arm 9000 up against sram chainset, you could try answering the chaps question rather than go all techy.

The 9000 and probably 9100 are the best rim calipers ive used, super record skeleton are good too, but dont have the quick releases.

Well, its etap then, ive fitted both Di2 & EPS to none internal frames, BUT to save being set about like, over my gear ratio,s post, ill not say how I did it, except to say, I am a frame repairer / builder.

Going all techy? That's the whole point of this forum. I give good advice based on experience, manufacturer's spec, and what makes sense. Your set up is over capacity of both derailleurs and I would never advise anyone to do the same thing. I'd hate to see what you might be inclined to do w/ any of your firearms given this attitude.

Didnt say I use it regularly, just said Ive done it and it works, it seems your attitude to look through, find something you dont agree with, and go ballistic, all you had to say was, there are draw backs to this set up, I would not recommend it, but if it works for you, good luck,
I still love you though, sorted the Etape, you were VERY close, but not total correct,
See how nice I made that sound,

No. I'm not going to agree with you and say 'if it works for you, fine' because someone else may try this and circumstances may result in a fairly catastrophic accident. I only say this because I've seen it in the past. I've been doing this a loooooong time at a pretty high level, and I've learned to respect manufacturers specs for good reason.
