No I am not. To use XTR mechs you have to use an MTB chainset. Using a GRX isn’t really a viable option so you’re limited to a top gear of 44x11 or smaller. The XTR mech will not shift the 46/30 or 48x31 11 speed GRX is offered in.
Right, but again this is obvious. Shimano are never going to allow you to electronically do something that the system has not been mechanically designed to do. They won't allow you to add loads of extra chainring gap into a system with a rear mech that hasn't been designed to account for it. I have already covered this if you would (FFS
) read properly.
Stock GRX gearing is fine unless you want to be able to climb steeper loose trails where 30 or 31 x 34 is not quite low enough. Being able to pair a GRX front mech & chainset with an XTR rear mech on 11-36 would be ideal. Hopefully the next iteration of GRX will have this as standard.
First, even Shimano are not going to put any real future effort into expanding the capabilities of MTB 2x systems. That line of tech is simply dead.
Second, if all you want is a GRX 2x system with an 11-36 you can do that now if you have a cassette. The 10sp GRX does it officially (because Shimano has a 10sp 11-36 cassette to use) and the 11sp 2x mech is equally capable of doing it, there just isn't a cassette of that size in the Shimano series.
Just buy a Sram or other cassette and you'll get exactly what you want out of an otherwise full GRX setup. Messing about with hacking XTR cross compatibility is completely pointless and unnecessary if an 11-36 on the back is the only thing you're trying to achieve.
