The NuVinci CVP (continuously variable planetary) internally geared hub offers many advantages over a traditional derailleur set up or even a traditional internally geared hub.  NuVinci hubs offer infinite gear inch choices within a 350% gear ratio.  See our photos for a gearing comparison.  That may sound confusing, but what it means is that you can always be in whichever gear you want.  There are no gaps or jumps in between gears, and the shifting is smoother and easier than any other drivetrain.  Never miss a shift or drop your chain, and unlike other internally geared hubs the NuVinci hub is silent.  The NuVinci CVP offers a no adjustment maintenance free (other than lubing the chain) drive train.  

Hub, shifter, vertical dropout kit, and brake kit are included.  Requires single speed freewheel.

Compatible with rim, roller, or 6 bolt disc brakes.  

135mm spacing.  

2 to 1 gear ratio recommended (ex36/18)
