A question for the experts. I am a bit OCD about the drive belt running off the drive sprocket by 4 / 5 mm. It seems to be the norm but is there any reason why a 4 or 5mm wheel spacer can't be fitted between the sprocket and the hub?
I believe there is a modified hub replacement probably at huge expense so why not just fit a spacer, there seems to be plenty of clearance and cost would be minimal?
Anyone fitted this before?

Did it two years ago, works fine, costs only a few pounds for a piece of alloy as spacer.

Great stuff, simple solution, did you change the bolts for longer or was there enough thread with the existing?

Morning Barry,
No, what I did was countersink the allen screw holes so that the screws sat deeper in their holes. this created the 4.5mm I needed to pack the sprocket out with an ally spacer. the ends of the screws protrude slightly into the inner part of the hub now. Once in a while I make sure they still have copaslip on the bit protruding should I need to take off. ( I have an alloy sprocket converted by SuperMax by the way)

Hi team,
Fitted a 5mm spacer and now have perfect belt alignment as well as improving the belt / tyre clearance.
Simple solutions as always the best. Original bolt length OK and still has thread protruding from back of hub

My belt clearance is quite tight so would not mind going down this path when I get a new rear tire. Can you share what you used for a spacer and any details?
