Very exciting.
red S3X fixed-gear hub, originally uploaded by BikeTinker.
I wanted a black one, with a bar-end shifter, but they only come in 36 hole spoke drillings. The only option for a 32h hub with 120mm track spacing is the red one, and it comes with a thumbshifter. It shouldn’t matter, because I want to do the Pants Pants seatstay-mount with it.
I did see that since it’s splined for a cog, and also threaded to receive (supposedly) a freewheel, it might be possible to stack two cogs up for ‘dingle’ (sextingle, actually) setup. The splines appear to be cassette or singlespeed/BMX cogs, rather than classic three-tab Sturmey or Sachs internal-gear hub cogs.
Very cool. I can’t wait to see the finished project. I might follow your lead. Keep those details coming…
somewhere in my parts bin is a shifter mount for an old cannondale 2.8 series frame.
the downtube shift levers were not welded on, but were a bolt on affair.
I should look and see if I have it laying around still, or you could swing by a local c’dale dealer and see if they have frame repair parts.
