Familiarity: I've put it through the wringer
Running a 32T QX1 on Giant Trance Advanced SX. Ring works really well for my pedal stroke. I tend to lose power coming to the top of the pedal stroke and this seems to smooth it out. It just feels better everywhere and I can hold onto the gear longer before I have to downshift. My only issue is that the spider you have to replace on the SRAM X01 (GXP) crank moved the chain line out another 6mm over stock! This made for a noisy 3 low gears and a nasty looking chain line in those gears. I ended up swapping the ring to the inside of the spider to bring the chain line back to stock. Works, but when you buy a premium product at a premium price, I expect it to fit perfect out of the box!
