so what is with bike manufacturers? i know that a 10 speed cassette sounds sexy and all that but why are they not giving us full range? why are they 12-25? why not 11-34? i want full range not a lot of mid range. is there a plot to take away hill climbing gears? and since they are usually a compact crank we are already loosing teeth on the front so then we get burned on the back with a 12?
