“Bike for Trail centre / peaks “
“1×10 2012 XT drive train”
IMO I’d want a 22/24T ring. Though I am more a pedal spinner than a pedal grinder/masher
If you’re going to single ring properly, then you’ll want a proper unramped single chainring. Which then means you’re paying loads of money just for XT crankarms, as far as I can work out, the chainrings are where all/almost all the 36?g weight difference between XT and SLX crankarms are.
If you want stiffness IIRC there was something somewhere I read saying the crankarms from SLX double/bash (steel axle/pedal threads) were twice as stiff (or maybe it was strong?) as XT arms
“Hope Pro2 Evo / Stans Arch Ex”
Arch EX, yes, as wide as 321/521/Havens etc. Id probably only go Flow’s if you were putting a 160mm fork on? After crest/arch EX release’s Flow ‘EX’ must be due though?
Hope Pro2 freehub isn’t the quickest to engage, though is pretty adapatble. Superstar switch evo is supposed to be very similar (weight, pickup speed), but I dont know how reliable they are, I know the customer suppost is hardly equal, not the wheelbuild quality ..
“Hope M4 Brakes”
Ive seen too many things saying they’re not all that powerful. Id probably be looking at lighter-weight codes, maybe marta’s or whatever they’re called now
“Hope headset & BB”
Shimano BBs are fine IME. Id wait kill that off first
“I want to spend mt time riding not fettling “
But you’re opting for fox forks/shocks?
Do orange 5’s go through shock bushings fairly quick?
