New cush drives revisited

Was just assembling a new batch of my cush drive hubs and I remembered some years ago a member having concerns about heat
transferring from the brake drum to the 6 vanes and melting rubbers, well to date after selling a lot of these hubs I've not had one
complaint regarding heat. That doesnt surprise me. From doing a bit of research its apparent that any melted rubbers on the standard 3
peg arrangement is/was caused by poor fit up,ie: brakes rubbing and or poor quality rubbers. similar to broken axles, often poor fit up.

Sooooooo much better than the mk3 cush arrangement! I'm very envious!

Work of art sir.... is that one of your minions in the last photo

I've purchased a few of Don's products and they're all absolutely first class, and he's super helpful to deal with. He even machined the rear cush drive hub for me to match my CNW front hub.

Yes, Don does some great products and backs them up with excellent customer service!

For the longevity of this fine looking setup, is the drum/sprocket available separately for when the sprocket finally wears out? Is the wear rate similar or different to the standard drum/sprocket?
Also, are the cush rubbers a one-off or are they an OEM part that is readily available? They look fairly substantial, so should last a while despite the Norton's mighty torque 8)

Yes the sprocket/drum is available separately, It is made from the same steel with hardened sprocket teeth as the OEM Norton one, so
with careful maintenance should last a very long time. If you ever you wear the cush drive rubbers out then I will replace them for free.
