Re: Skyway hubs with IFI sprockets?

They kind of are standard. The 1.875 bolt centers are the same but the center clearace hole for the bearing is not, so IFI sprocket do not self center on the plastic hubs with Skyway wheels. Be sure to use counter sunk flat head screws with the aluminum sprockets. That helps them center.

When we switched 6 wheels from steel 28 tooth sprockets to 28 tooth aluminum sprockets we saved about 3 lbs total.

Also remeber that the Skyway wheels are slightly smaller than the IFI true 8" diameter wheels. I think that was covered in another thread.
