Does anyone have any experience with using the new shimano 11 speed crank with the 10 speed groupset?
I currently ride a compact ultegra 6750 crank and am consider making the switch to a double as I rarely use the 34t unless its a pretty steep hill. So I'm thinking its time to man up and make the switch
I'm also thinking it'd be a good opportunity to drop some grams and upgrade to the new Dura Ace 9000 crank, but this is 11 speed (it might have to be the ultegra 11sp if I can't find the DA discounted enough).
I know Shimano's bottom line is that the crank is not compatible, however I have read a few customer reviews on wiggle saying that they are running 11 speed crank with 10 speed group set without issues.
I was wondering if anyone on here had any experience and can confirm the compatibility without dropping the chain on every downshift from large to small ring?
As a follow on bonus question:
I have a 11-25 cassette, if I make the jump to a double, what is the normal ratio people have on the back?
Is there a website anyone can recommend that give the ratios for all the different chainring and cassette sizes?
Thanks in advance for anyone who can answer any of my questions.
