The product testing must go on. I've been riding this Nuvinci N360 CVT hub in my Fr8 for maybe 1 1/2 years and like it. But my bike seemed to have a lot of friction so I took it apart to find the problem. It wasn't the hub; It was the IM80 rollerbrakes that had gummed up with a paste of grease and dirt.
The rollerbrakes were thoroughly cleaned and instead of Shimano's sacred, special grease I lubed them with OIL instead. Now they run much more freely and brake more powerfully than any other rollerbrake I've tried... but for how long?
