The Joule 3 currently is the lightest, most efficient bicycle dynamo hub on the market. It can be built up to create super-light dynamo wheels and its patented magnet configuration reduces drag and offers a 75% efficiency rating. Polishing, laser etching, and a precision machined flange pattern give high performance in a beautiful small package. Winner of a 2012 Eurobike Award.
