16:8 prototype

This spintec hub has been specifically designed for building with 16 spokes on the drive side and 8 on the non-drive.  The rim is a kinlin niobium 30mm.  Its possible to build the same configuration with a normal 32 hole hub on a 24 hole rim.  The theory says that building a wheel with half the number of spokes on the non-drive side will allow even tension on each side.  A normal 1:1 road wheel will always have lower tension on the NDS due to the wheel dish.  Theres some serious physics involved in the forces put on wheels in general use.  We're not sure this provides any benefits over a normal spoked wheel, as a good hand built wheel will be as strong and stiff as you want it?  But this one has been test ridden by ourselves and it seems to do what it says on the tin - smooth, stiff, light (840g for the bare wheel).  We went for a 3x pattern on the drive side, and radial on the NDS - the result looks a little like a crows foot from the side.  There are many different configurations with this set-up, but we went for pairing the crossing spokes on the drive side against the one radial spoke on the other.  We'll keep riding this and hopefully have more to say over extended usage.
