Any how .. want crank arm covers and got the dosh to pay for them?

Swiss Machine designer Florian Schlumpf, for his 2 speed planetary cranks ,
they make a stamped cover for the crank arms, because the shifting is done with the center button

where a dust cap would be , but its purpose is to make the shifting between
button in on the right , out on the left, and the opposite in on the left proud on the Right
easy.

the recent improved version uses a steel button on the end of the shifting shuttle, and a magnet in the cover
so it wont rattle.

The 2 speed cranks are great , i got one for my Brompton M3L. adds 3 more much lower gears.

Schlumpf also makes 2 overdrive cranks , aswell
