3 rd hub has now 2374 km mileage, no problems. I can say that its behavior is the best (compared to previous 2 ones). It seems to have the lowest power loss, no „slippage feeling“ and no masive leaks (maybe hub is a bit oily, but no fluid on the floor under parking bike or on the rim).
Although you can see here many problems reported by me, I am permanetly convinced that NuVinci N360 was the good choice. Its benefits for everyday cycling are evident. You easy get used to this its shifting abilities.
