No need for a left hand shifter with the new Di2 (MTB...)

DiscoBoy

Syncro Shift allows the rider to control both front and rear derailleurs with one shifter. Simply shift up or down and the transmission will follow a pre-programmed (and customisable) shifting map, moving both dérailleurs when necessary to find the next ratio while maintaining a good chain line.

I guess it is pretty useful for MTB riders. Less useful for road riders, but a fairly nice feature. It's not exactly an innovation as it was done on 7970 by fairwheel bikes in 2010:

p.s. I imagine that this will be fairly easy to implement on 9070 and 6870 setups, due to the shared hardware with XTR Di2.

Similarly useful for both I would think. Though I have trained myself to double shift when changing the front ring, it would be nice not to have to.

I am fairly interested in the MTB news though. When I got my new road bike with Di2 i did think - what I really need is this on the MTB (because of all the mud and crap, on a long XC race I have ended up with only having about 6 working gear combos). But this first set confirms what I had concluded back then - Di2 is way too expensive for MTBs.

The problem is it is not at all unusual to rip your rear mech of when you crash or it hits a rock or whatever. At £35 for a new mech that's not too much pain, but at £425!!!!!!!! That would really really hurt.

You get so much more for your £ on MTB.

We still haven't properly got disks on Roadies yet.

The reason I said that is because in a road bike you don't have much to think about/ do (as a rule) so an extra bit of thought into changing gear is no hardship. Whereas on a MTB it is a big benefit not to have to think about how to change when there is a tree in your path.

That's an excellent point about breaking your mech, though

My wife will love this. I suspect this could be a game changer for many women. My wife and many women I know have problems with lefts and rights and with working out the chainrings and cassette. Never mind that the big lever on the left is for going faster but on the right is for hills!!!

But just give her left hills and right faster and she will be fine.

I've set my (road) Di2 up in paddle shift mode.

The buttons (calm down EPS users, these ones are reachable) work the chainrings left and right, the paddles (the rear switches) work the cassette.

Try that with cables



There is no reason to be tied to ye olde cable layout and I hear the new SRAM electronics come like this as standard.
