So... I counted my teeths and turns out i am running 16t cog on 55~t chainring x.x i mean, wtf? but i dont think my dad will let me get a new crankset nor the bike shop will accept a full refund because the tires are prettty dirty. It'd take atleast one or two months before i can buy a new crankset with my own money. The ratios are really weird huh? Can't believe i've been riding these intense nj uphills in this bike x.x
