User Review: Shimano XTR Di2

Recommended Posts

It would be nice if it had a little button like on the garmin cadence sensor that when you push it then push the shifter it pairs. Then it ignores the advances of other devices. :P

Thank you for putting in the time and effort. Great for me as a layman in drive trains.

 

Again much appreciated and well done  :thumbup:

More importantly, you spent R35k on a drivetrain, but still run Alu stem and bar???  Sies man!

 

^_^

 

haha, yup, further upgrades may be on the horizon. I was actually going to get the Pro Di2 handlebar and stem, which routes the Di2 wires internally through the bar and stem. But apparently there is some problem with the stem and it keeps slipping. A problem with some new technology on that piece of equipment to allow for the battery to be housed down the stemfork if necessary.

 

Also, with the Pro handlebar and stem, you forego the neat chainbreaker and chainlink in the stem system that Specialised has developed. I am not sure that I am prepared to let go of that little piece of genius.

 

But as I said, weight is less of an issue for me. I want clean, crisp, reliable and relatively maintenance-free shifting - I can actually feel that value-add.

I am running the Di2 on a 1x 11 and must say, totally stoked so-far.  Definitely one of the best investments I have made into my cycling equipment and my MTBike machine.

Interesting that you went 1x11. What was your reason not to go 2x11, given synchroshifting?

GrantRH - couple of things, was running 1x11 already, and very happy with it, have an Epic WC (so no place for the front derailleur), weight (LOL) and simplicity.

just that price tag sho sho sho 

I agree, and think that is the big negative, functionally they seem to have gotten it very close to right from the word go.

 

Lets face it, if electro cost the same as mechanical most of us would go electro.

 

Edit: After 2nd or 3rd Gen.

What I do not understand; is when I should up to a race with battery powered motor connected to my drive chain, suddenly I'm a "cheat" and was asked to leave???

I would have thought for MTB a complete wireless system should have been developed from the word go, as that's the biggest weakness off road, one little branch snags your wire and its cut in half and you single speed home.

 

I guess that will be 2.0, just sad they did not do it from the start.

I dont like the idea of wireless.....separate small batteries for each component with no option for in-ride charging Rather standardise on an in-frame battery mount with internally routed cables that terminate at standard weatherproof sockets at the FD, RD and headtube areas.

 

The FD location can be used to connect rear shock too, the head tube socket could also manage a connection to front shocks and the RD position also connects the hub generator.....

Those electric wires look pretty robust. More likely that they will be pulled out the socket if snagged on something. In which event, dismount, plug back in, remount, ride.

what does one do if you are running a dropper post with respect to battery fitment to the bike?
