Ultegra 6700 chain rings question

[Dromen]

Are these cold forged and have same ramping/pins as dura ace 7900? I guess maybe the question is...are shifting, durability, stiffness same as dura ace?

[Pete Mckeon]

yes they are as good and durable. I have used both for a long time. My S&S travel bike has Ultegra and I have been very happy with it for the past three years. :)


yeah I like Dure Ace also. PETE

Like the ones for DA Di2, these are made for the rigors of Di2(Ultegra) front shifting. So they are stiff, durable, shift really well, and plenty expensive.

'About' $125 for the 6700 big ring, $280 for the DA big ring..no prices on 9000 yet.
