The 'flushing oil' has a blue label and is called Cleaning Oil.
The regular oil has a yellow label and is called All Seasons Oil.
So clean it first with the Cleaning Oil and then apply the All Seasons Oil. Simples! Note that it is generally a good idea if you are storing oil for any length of time to keep it somewhere dark, away from sunlight.

This also is true. Though on the smaller bottles the Speedhub oil label is green.

Yes, it was already in my mind to fit one of those at the next sprocket change.
I didn't find the original design too difficult to deal with but this splined adapter (with splined sprockets) must be easier.
The splined arrangement is good, it is now a doddle to reverse or change the sprocket. There are two sizes so it is a good idea to check which gives the best chainline. Thorn suggest the smaller one works best for most of their bikes. I got the standard one before the smaller was available and it works fine in every practical sense but might be tricky for those using chaingliders.
The slimline one, which I just bought will not dictate that you get a wider BB to get a more or less perfect chainline. The original one pushes the chain out about 3mm, so if you're a perfectionist you may want a 6mm wider axle system. I won't be using this for a while as I haven't reversed the current sprocket. I find that these give great mileage. I can usually get 3 chains though one side of the sprocket and the chains are cheap.

Also if you use even-even setup (16 sprocket with 40, 42 etc) if you take wheel off, you can get the sprocket in a different phase with the chainwheel and this causes rumbling. If you have such a setup, change phase frequently OR mark one of the teeth on the sprocket so you can put it in phase... This is hard to explain!
Ok. I cleaned the chain (properly with a toothbrush and pot of white spirit) removed and cleaned the chainwheel and sprocket. I dont know if I reveresed the sprocket on reinstalling or not but I could see no signs of wear and then changed the oil. Did seventy miles on it this w/e. Result - no more rumbling. So what was it. Was it old oil? How could dirt in any or all three parts of the drive chain cause that rumbling?
