Shimano road 12 speed?

[jpang922]

This is probably why Shimano and Campy hasn’t forgone the wires yet...

It's funny if you look at the patent images. One shows a Campy Ergo lever!

Aside from that, Shimano and Campy both have patents for semi and fully wireless shifting. A big issue is the battery drain. That's why FSA went with semi wireless with the main battery driving the derailleurs. That's what takes a ton of the load.

I want to know how much farther and faster this is going to allow me to go?
More than content with what they are providing now, it's like thinking more grease is going to allow me go faster, once you get past reducing the friction more is just dead weight.

Maybe Shimano will design cranks that don't snap.








I'll see myself out.

I predict(been wrong before) that 12s Di2 will have ders hard wired to a battery and ONE battery in RH shifter, which will be wireless and the front der will be 'smart' and shift by itself depending on which cog is selected in rear, ala XTR.
Campag 13s, 1by, will be same..with one battery internal and one battery for RH lever.

I like Old Tater Group concept, I'd add cog count programming,
I'd like to use 9 of 10 speed on some older bikes.
Electronic 5s with auto half stepping for for IBOB crowd.

That is how I run my current Dura Ace. I have really grown to like Syncroshift. The left shifter I have setup to switch screens on my Garmin.

-one Red derailleur snap at the knuckle;
-one Sram quick release loosening and opening on a ride, causing a crash.

The only well-made Sram part I had was a first gen 10 speed Red RHS shifter; eventually sold it to a guy whose Sram shifter snapped...

I was an evangelist for Sram stuff for so long, but those are quite inexcusable.

Shimano may be heavier, but it's functional, sturdy, and reliable.

And here I sit having had none of those Sram problems, and plenty of Shimano problems. Specifically the shifter cable snapping problem and multiple crank failures...

It won’t make you faster or ride further. But I went from 8-speed to 10-speed to 11-speed and each time not only did I get more useful gears and better gear spacing, the functionality improved.

When the old stuff wears out there’s no real reason not to move forward. My 11-speed 105 blows my old Campagnolo Record 8-speed away in every possible way except aesthetics.

Curmudgeon response: IF they dump rim brake on 12 speed groups 11 speed will basically be where my new purchases end; I'll stock up like a fool and be content until I die, probably.

Sick of spending a LOT of money for new "standards" to be released, repeatedly ...

Carry on, but stay OFF my lawn

The biggest pro cycling team in the world exclusively uses shimano rim brake groups (and Italian bottom brackets.) Hard to see an entirely non-rim brake group while that’s the case.

Plus, how much does it take to iterate on their rim brakes at this point? They’ve had it figured out for generations.

What team is that?

Name escapes me. Big into margarine pains or motorized trains, something like that.

Are you sure it's not butter pains?

Perhaps I am not as enthusiastic as I used to be when it comes to new groups. My 11sp mech rim ultegra works so good, provides more than enough gearing, is easy to work on. If the new 12 sp (assuming 12 sp) is really pretty, and offered some “actual” improvements I might be tempted, but if all my old wheels need to be replaced I think I will happily just sit where I am. Honestly there is not much room for improvements in the current groups from all 3, but we will happily wait and see......
