I guess my question should really be, barring a bargain 11sp deal, what’s the very best value/performance 10sp set up?
Again though, that’s subjective… I’d say an XX 11-36 cassette with XTR mech and shifter. But an XT cassette with expander would give more range. It would weigh more though, but it would cost far less.
That said, I wanted the range of XX1, so an entire XT groupset for £50 wouldn’t have enticed me, YMMV.
The thing with XT et al is that you don’t really want a groupset – you don’t want a front mech or a triple chainset, you’ll need (/want) an expander and a narrow wide ring etc, so whilst this is about 1/3 the cost of an XX1 groupset it’s a chunk heavier, it doesn’t have the range and it has a load of parts you don’t want. It’s £400 cheaper though, so does that “knock SRAM outta the park?”. For me? No, it’s something totally different. For you? Maybe.
might be a good time to admit that the 650b wheels I have a deposit down on have Hope hubs with I believe a Shimano freehub?
Assuming they’re new you can possibly still get them supplied with XD body, if not you can buy one separately. It’s potentially an additional cost though, which may make the “value” of a 1×10 transmission more appealing.
