They haven’t arrived yet, postage to Australia takes a long time at the moment. I didn’t think to measure tbh.

*edit - well they just arrived and I can confirm that the original needs the 5mm ones that you ordered, and the Nova will use the 4.2mm as I linked above

Oh - that's interesting. I put Novafox driveshafts in my vintage Fox, and reused the original plastic hubs. I didn't notice a size problem.

I imagine the 5mm holed hubs will fit on the narrow shaft without a noticeable effect, the pin will keep it balanced anyway. (unless there are 2 versions of axle on original Foxes?)

I’m not sure - I measured the driveshafts on my vintage fox and they are showing 4.8mm using a digital caliper. With the 5mm aluminium hubs fitted and the wheel nuts are fully tightened, there’s a tiny bit of play, it’s minuscule, but it is there. To be honest I think could be wear on the original shafts, but even the 0.2mm difference gave a tiny bit of movement.


If the Novafox uses thinner diameter shafts, I wouldn’t advise the 5mm hubs, going off the above

Thinking about it, they can't be thinner on the Novafox. They still use an 1150 bearing (so nominal 5mm diameter there), and it doesn't step down in size to where the hub goes. I'm mostly just being lazy not bothering to take the wheels off and measure mine, but I reckon it must be nominal 5mm on both original and rere. I think I would have noticed if there was loads of play in the hubs when I rebuilt mine anyway (new Novafox driveshafts, original 80s hubs).

This is a very good point, I eyeballed the alloy ones to some genuine Nova Fox ones in my spares and they look identical, I pulled a wheel off of my genuine Fox and the alloy one won’t fit, might need to pull a wheel Andrew hex of my Nova to check

If you need me to measure things then I can; I've got the original Fox ones (replaced back in the day and worn out again!), the original, original early Fox ones (taken off in the 80s when they wore out), and Novafox ones on the car now (I bought the relevant Novafox parts bag). I don't want to take the wheels off more often than I have to as the original hubs are past their best, but I can measure any of the above.

It’s ok, I have a NiB original, 2 built originals and a built Nova with Hex’s so new standard Nova hubs as well. I can check them out. I’m extremely curious as to why they offer the smaller hole ones now. I’m thinking if I need to I will drill out these ones I got to the thicker 5mm

Very interested in this... Will open my Novafox box and measure, just to compare
