!!sp 105/Ultegra rear derailleurs compatible with 10sp drivetrain?
So I need to replace my rear derailleur, but was hoping to grab one of the newer ones. Will a new 11sp 105/ultegra rear mech play nice with a 6700 12-30 cassette and 10sp chain, or am I out of luck?

Nope, the derailier speed needs to match the shifters from 10 to 11 speed.

If you install a Shimano 105 11 speed derailleur to use with Shimano 10 speed shifters and a 10 speed cassette, no reason it will not work fine as long as you set the low limit screw accordingly. I'd have to see how the new 8000 would install, but that might not even be a problem. Not sure why one would over a 10 speed unless you wanted the 11 for a future build. Nothing to be gained in performance. |

What I mean is a 11 speed rear derailuer wont work with 10 speed shifters. I dont know the cable pull ratio but they are not the same and wont work. |

He understood you, he just has the wrong information about 10 and 11 speed compatibility. Probably because 7 to 8 and 9 to 10 were compatible.

Yeah, then there was all that mountan hocus pocus.

What's the difference? Guessing cable pull? |

Yup, cable pull. It would be like trying to use a Sram derailleur with Shimano shifters.

I actually recommend a 9 speed derailleur, the M591. It has more chain wrapping capacity than any 10-11 speed road derailleur that Shimano makes. It's the last of the great road-compatible/mountain long cage derailleurs. A true classic. Last edited by Marc40a; 11-12-2017 at 09:55 PM. |

I had a dream last night that all the major manufacturers agreed on standards for everything and going forward all parts would be interchangeable across brands.
I was so disappointed to wake up from that and realize it was just a dream. |

They have agreed on so many things that you can buy a frame and equip it with components from any company. Now you want them to check in with each other every time they redesign their index systems?

Bottom brackets are a clustermuck. Everything else is pretty hard to make proprietary without being obtuse. What are they going to do, change which side is drive side? Have a weird angle required for the deraileur hanger? They didn't need to do anything to allow frames to be independent of groupset.
