Thanks for your feedback.
So far only "onrbikes" member is interested in sharing the cost of 1 l speedhub oil and 1 l cleaning oil. When I have another 4 people interested I will look at the logistic details (postage and small bottles) to let you know the final cost, that there is no doubt will be much cheaper than buying 25 ml bottles.
I will postage from the UK to the UK.
No intention to make any profit, I do it for the shake of the good cycling fraternity!
