See the pictures, but I know it is hard to see but some of my rear gears have the top nipped off, almost like a lead in tooth and they all seem to be evenly spaced on the gear sprocket. So is there such thing as "lead in teeth" that make gear shifting quieter and smoother or am I just thinking up magical things.
If you look closely at the side pic you'll see the shorter teeth, and then on the above pic you'll see a narrow slanted top on some and the stubby, flat top on others. The stubby and flat ones are the shorter teeth.
Any help is appreciated!
Here are some pics:
