Reactor Stem Cap USB Charger

In partnership with our friends at Sinewave Cycles, we are proud to offer the Reactor Stem Cap USB Charger. Charge any USB device when you are on the go - cell phone, GPS, headlights! The Reactor fits above the star-fangled 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, black and red. The Reactor is compatible with 1" and 1 1/8" threadless systems.
