New dura-ace R9100

[sennder]

i might have missed something, but i can't seem to find a 9100 short cage rear derailleur???

There doesn't seem to be any. They have adopted a single "mid cage" option to accommodate all cassettes up to 30T.

[ooo]

they made it mid cage, but they still call it short cage (SS)

How very American of them.

Does anybody know the differences between the two new D-Fly units (EW-WU101 vs. EW-WU111)? Thanks.

Looks to me like one is made for internal and one is made for external. Look at these two pictures. The 101 version looks like the old D Fly that was supposed to be attached to the seatstay (of course most of us put it inside the frame anyhow). The 111 is different. It has its connectors in line and is thinner and has no attachement "ears".

I did notice the form factor difference between the 101 and 111, but couldn't determine if there was an accompanying functional difference.

Wonder if the latest 30t cassette can be used with current 9070 setups..

[bikemaniack]

Probably no.

9000 on an SL4 will handle a 32 trial and error.

Do you guys have a link to a technical synchro-shift page?

If I'm not mistaken, older di2 groupsets will have access to synchro-shift (6870 and 9070). I also know that the new battery is required.

But do we know if we will need other new components? New junction box maybe?

Same will levers. New levers needed or old Ultegra, DA and R785 are fine?

So I am asuming that the frame tubing presents no obstacle for the wireless signals to get through and reach it and to get out to whatever device would be looking to receive that signal?

Any more info on the actual release dates?

[ms6073]

That is a good question, especially considering that there did not appear to be 9100 equipped bikes on the road during the Tour, nor the Olympics. Wonder if we will see 9100 equipped bikes making an appearance at the Vuelta?

Does anyone know how EW-JC130 y-sprit rooting is for?
