Does anyone know the difference between the stock disk hub and the Norvil one?

Mick Hemmings offers two different brake kits, one complete with new hub and the other to adapt to a stock hub.

Thanks.

Norvil hub takes two six stud discs standard hub takes one five stud disc

I have a RGM hub that looks the same except it's a 5 hole for the disks

Hi Dave
I have a Norvil road race wheel with an akront wm2 shouldered rim, less the brake disks. The hub is made to fit one or two disks. The Norvil wheel is different from the stock road version. The hole pattern is 6 instead of 5 for the disk/s and the spokes are central in the wheel with equal length spokes. The spacers are also different than road bike version. The axle is still the same. Where the street hub is a casting lump and offset spokes the Norvil is machined much nicer at the hub and lighter. Funny I was looking at mine yesterday and contemplating to re-spoke it in Stainless Steel. I purchased the spokes 2 years ago and I plan on putting it on one of my combats.

The front axle (spindle) is NOT the same. The drive side slider doesn't have a pinch bolt on the bottom as per standard Commando.

The spindle is the same diameter all the way through, not stepped like the standard Commando one.

It is all clamped together between the sliders with the correct sized spacers, what a lot of messing about to avoid stichion!

Here's a view of what an original Norvil hub looks like between the spoke flanges.

I'll just get the kit with the new slider and keep the existing wheel. If I hadn't just had the wheels built it might be a different story.

As this is in no way trying to be an exact replica getting the correct front wheel isn't that critical.

That is interesting. To be honest I purchased my wheel at a bike swap meet many years ago and it came with the spacers and a stock axel with nut. Maybe what I have is for converting it to only a single disk. Looking at Ron L picture, my center doesn’t have the raised boss with the Norton stamped around.
