Are there any multi speed skiptooth hubs out there or any that anyone has converted successfully? I really want more speed out of my rat but also cruise so I don't want it to be killer to pedal at low speed. I really like my skiptooth setup but just wondering if I can get something like a sturmey archer 3 speed with a skiptooth cog? Let me know if you have any leads,pics,deals, or swap info. Thanks
