The hydrolic is nice but certainly not "weight weenie". Not to stray off topic....
Would be interesting to see a 1x 11 offering for weight weenies. Are we not getting to the point where the FD is superfluous for many?
With a Wi-Fli RD and an 48 tooth Front and 11-32 cassette you effectively have 53-36 12-25 which should be more than enough for anyone.
However it would be neat to have a 10-36 Rear cassette which could effectively give you absolutely silly range - More like 12-30 on a 44 tooth Front.
Are XX1 indexing and SRAM 11sp indexing the same? Will a XX1 RD work with new SRAM 11sp?
There are lots of options for XX1 Rear Disc hubs.
I've done many miles... thousands... with a 48/38 and 11-32. Although you're not left wanting for climbs, it's not worth it over a standard or even compact crankset, at least for me. The cassette spacing makes keeping cadence in races or spirited group rides very challenging; one gear down and you're spinning like mad losing the wheel ahead of you, one gear up and you feel like you're in mashville. I also regularly run out of speed in 48x11 on some of the long descents around here.
I love the idea of 1x10 or 1x11, and I think that it's well-suited for cx and mtb, but it seems to me that well-rounded road riding necessitates a certain amount of subtle precision that you can only get with a 2xX spread.
