Re: A new shift concept for the engineers....
1) buy a fixed gear 3-speed.
2) attached sprocket to hub body.
3) install 22 tooth fixed gear cog.
SO everyone does realize that the s3x does not freewheel with a cog? And the cog does not un-thread when you drive it backwards? the s3x will drive on the left side and shift!
Maybe that's what some of you are over looking. 'fixed gear' bicycles do not free-wheel. The s3x is a fixed gear three speed.
