NuVinci Hubs

The NuVinci Hub is continuously variable

Fallbrook Technologies has an innovative product that allows for continuously varying your gear ratio. Actually gear ratio is not the proper term, because there are no gears. Instead, power is transmitted through rotating balls. Here's a video that explains how it works. There are a number of reviews of it out on the Internet (Utah Trike, MTB), and here's what they say in a nutshell:

• It's very smooth
• Since it is infinitely variable, you can fine tune your gearing
• Shifting is very easy
• You can shift while stopped or coasting
• It is reliable and requires little maintenance
• The only downside is that it is heavy, weighing just over 5 pounds

The Nuvinci hub comes as standard equipment on the Origin-8 Crawler mountain bike. Stop in at Circle City Bicycles and take one for a spin.

Fallbrook Technologies sells its power train technology for a wide variety of other applications including:

• Cars
• Trucks
• Lawn Mowers
• Wind Turbines
• Electric Bikes
