TBH I’m increasingly tempted by the features offered by XX1 including it’s weight, but the cost is still enough of a deterent, the “halfway house 1 x 10 solutions: XX “Style” aftermarket rings and modified 10 speed 11-41t Cassettes, etc hold some promise and I think are an indication of the “proper” products that will be coming out over the next 24 months.
Of course proper weight weenies never “just” but a whole groupset, there’s always grams to be saved by chucking more money at aftermarket trickery or removing an unused ring or sprocket…
I’m waiting for the day when 7 speed makes a formal comeback as the “Super-light” solution by getting rid of ~30% of the Cassette mass and then we’re basically back to about gearing we all had in 1991…
As it is I’m still sticking with (heavier) SLX – 2×9 until something that functions/weighs more like the current XX1/X01 can be had for something like current XT money… probably a way off yet…
What I’d realy love too, is to see Campag get back into the MTB drivetrain market, I doubt I’d actually buy their products but having 3 main players in the market might precipitate some faster and more innovative product developments… This 2 horse SRAM Vs Shimano race is a bit dull and slow at times TBH…
