Hi, Will The Supernova The Plug Iii Hub Dynamo Powered Charging Device Fit My Thorn Mercury?
31 May 2016
I assume that a wire passes down the steerer tube. There looks to be an opening at the bottom end, but I wanted to check before ordering. By the way, the Mercury is going very well.
SJS Customer Service:

The Plug 3 can indeed be fitted to your Thorn Mercury. The wires would pass down the steerer tube and out the bottom at the fork crown.
