When will hubs be available that allows a keyed shaft to be used with the IFI Wheels?
**At the current time, there are no plans for IFI to sell keyed hubs for our traction wheels.
We encourage individuals to develop their own bolt on hubs for these wheels. The specification sheets and solid models for the wheels should provide adequate informtion to design such a thing.

The current wheel design allows for mounting of a sprocket directly to the wheel itself for drive. Bearings mount into the wheel side-plates, such that the wheel spins freely on a live axle.
The hubs refferred to on our wheel page, are the flat plates which bolt onto the outside of the wheel. These are NOT keyed hubs, but are designed to mount a sprocket, and a bearing.**
