Product Description


Introducing the Sinewave Reactor! 

We’ve taken the performance of our Revolution dynamo-powered USB charger and shrunk it into a package that fits above the star nut in a threadless steerer tube, with a pass through for the 6mm bolt.  The only visible part is a custom CNC-milled stem cap holding the USB connector. 

The cap is only 9.8mm tall and available in silver and black.  The Reactor is compatible with 1″ and 1 1/8″ threadless systems.
