I'm a newb to all this 2*10 shit. Would these be compatible with shimano 2*10? They'd be standing in for an xt 2 by set of cranks with 24/38. Bike is a 2015 trek fuel ex 9.8 29r. Looks like a press fit bottom bracket. I've got no idea about these new fangled standards and/or how to measure them. My back is telling me I could use some lower gears for my 24hour solo push though.
