1x versus 2x for old 26" MTB build
I'm getting ready to assemble another MTB and thinking about trying something different this time. My other MTB (which might get drop bars...) is pretty traditional with Shimano trigger shifters, 8-speed 11-34 cassette, and an XT square taper crank setup with 26/36 (Biopace!) chainrings.
My new frame is also 26", hardtail, rim brake. I don't have all the components I need so it's a bit open ended. I like my current setup a lot but wondering if 1x might be a better way to go. The cassette is obviously heavier but it eliminates a chainring, front derailer, front shifter, etc. I'm confident I can get a gear range I'm happy with (or I won't do it...) Has anyone done the math on this regarding weight? Is 1x actually lighter or is it just a way for OEMs to save money? If I go 1x, any crank recommendations? I have to imagine there's something out there that's lighter than the old square taper cranks I run on everything. Just keep in mind it needs appropriate chainline for a 135mm rear end.
