Here is the link to the hub gear:
I was hoping to use this hub in my Dahon Helios. This allows me to keep a direct chain line (love the feel and efficiency without a derailleur and chain jumping issues) while providing a climbing gear and flat speed gear.
1) My Dahon uses a 130mm hub width. Is this going to be a problem?
2) My Dahon wheel uses 28 spokes. This hub uses 36 spokes. Is this OK?
3) Has anyone used one of these new S2 Duomatics? Is there drag with normal riding or is it virtually transparent even to a picky user?
