more teeth on the crankset just means you can higher gear ratios on flats and probably downhill (if you're pedalling). ang tanong diyan is gagamitin mo ba? kung yung 44x11 nga never ko talagang nagagamit, yung 46x11 ba magagamit mo?
More teeth=lower acceleration because harder to pedal. Difficult reaching top speed, unless you're going down a slope and are able to sustain your pedaling. Less teeth=faster acceleration because easier to pedal. Easier reaching top speed.
I think the Alivio is easier to pedal than the Aeroic.
I have a 1x10, 42x11, 30t setup. For me, I find I accelerate much faster. On the road at top speed, what I did on my hardtail (3x) at 50kph, I did it at 48kph on a 1x10 setup. Climbing up a slope is pretty much the same effort on both bikes. That convinced me I don't really need a 3x setup. It's way too much gears, too much clutter (bar and crank) and useless paper weight. I'm glad they shaved it off to just the minimal.
