Saw these and thought to share. Reminds of how much most all the current tech we have is actually recycled innovation from long ago. Of course these are steel and the cog is inch pitch.
Now THAT is a fixed cog.
They look alot like mavic straight pull hubs don’t they.
The front reminds me of rs30 shimanos off my road bike. Similar look, except these are probably off the charts light, lol
