Re: Showdown: Shifter type

The thing I don't like about dog shifting is after a while the dog gears can get wobbly because they are only on one bearing. The thing I don't like about mesh shifting is every one of them I've seen is full of metal chips/dust from the shifting. The thing I don't like about ball shifting is the friction between gear and shaft.

Dog shifting may be a little tougher to make but it requres less space and gears than mesh shifting and is probably more reliable.
