Sram Red GXP crankset + bottom bracketMy 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.
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.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..
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.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.
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.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,
