NUVINCI N360 INTERNAL HUB

Some say that when it comes to internal hubs this one is the best. One reviewer described it as “gears without headaches”. At the $320 to $400 range it is reasonable. You can certainly pay a lot more for an internal hub. It is available in 32 or 36 hole (spokes) and silver or black. It can be shifted effortlessly while sitting still or under load. I believe this unit weighs 5.4 pounds. For comparison a typical front and rear derailleur system weighs approximately 3 pounds.

Wikipedia says “The NuVinci CVT further offers the ability to accept multiple inputs while varying speed and ratio, managing torque and providing single or multiple power outlets.

Personally I like the idea of having an internal hub. I doubt very much if I will ever have one at this stage of my life. Being able to shift while sitting still or when you find you didn’t downshift when you should have is a real plus with these hubs. They could easily help us to …

ENJOY THE RIDE!
