Excellent! Thanks for the report, Bill. It really is nudging me towards the S3X. If the slack in the system isn't too bad, the other stumbling block for me is the cable-run. Did you ziptie the housing to the top tube? I'd love to see the photos when the Round Tuit arrives. If I get one, I'll keep your cones and cable-slippage advice in mind. Does the hub freewheel if you miss gears?
I'd like to engineer a little widget to mount the shifter at the seatstay boss instead of the bar-end. (I'm thinking sawn-off piece of drop bar mounted side-on) What size ring and cog are you using? Something that attracts me to the S3X is just poking numbers into Sheldon's gear chart... with two rings, 40 and 44 look really good to me with a 15t cog. 46" - 56" - 73" and 50" - 60" - 80" Then there's the possibility(?) of threading a dingle cog on there for even more fun (44/52 x 17/21?)... My inner nerd is my outer nerd.
