I find that gears 1-3 are way too short for the kind of riding I am doing: 70% street / 30% bush trails on Metzeler Enduro 3 tires. Thinking of going down on the rear sprocket to 47T or even 46T. All mods done so I have amazing power right now with w/ the 50T. Just looking to stretch the gears. My question is: how significant is the loss in power if I drop down 3 or 4 teeth? Basically, has anyone done this and wish they didn't? Thanks.
