This is sort of a noobish question but I am curious about how my bike shifts and if any of you experience the same problem. When I am shifting to a low gear (small to big sprocket) if I press the lever lightly it clicks, and the derailleur wants to move cause I can hear it gringing against the next gear, but it doesnt or the shifting is delayed. However, if I push the lever with more pressure the shifter clicks and the derailleur shifts easily. Is this normal? Does it just take a bit of muscle to get a clean shift?
