I 2nd a wheel swap for comparison.
I 2nd a wheel swap for comparison.
I third the wheel swap idea. It looks like you have a mountain casette in the rear. I find when I ride the same bike with a 11-34 mountain casette vs 12-27 road casette it feels more sluggish cuz the gears are further apart, although if I am doing it cuz I really need the low gears, I need to do it. Your saddle also looks quite far forward in the pic, so perhaps you aren't in an effeceint pedaling postion. Do your other bikes have drop bars or flat? Could the twtichiness make me feel unstable and hold back on your speed psycologically. I don't understand why it was built with such a short wheelbase. Just some random thoughts. Please try the wheel swap and report back to us.
