Shimano freewheels

Brownish gold cogs (color, not material) with a black big one. Reliable Shimano removal system.  Anyway, Shimano backs 'em, so they're good.

new for 2020: they are all (mostly) silver, not brownish, they come with a removable pie plate spoke protector, and there's a 6 speed x 14-28 option, neat.
