I take it that it will not fit a 1" steerer?

Hi there,

This is designed for 1.1/8th steerer tubes.

Will the Plug 3 fit on my Thorn Nomad Mk2 ?

Hi Will The Supernova Plug 3 Fit On My Thorn Sherpa?
05 Apr 2017
Hi will i be able to get the wires through the bottom of the fork crown as the front mudguard seems to be fixed there.

This Supernova Plug 3 will fit to your Thorn Sherpa. The easiest way to wire it is to temporarily drop the mudguard off feed the cable out through, fix into place and then re-fit the mudguard.

Will This Fit An Overdrive Steerer?
18 Mar 2017
I have a Giant Defy Advance Pro 3 2016, which has an overdrive steerer. My current headset cap measure 40mm

Unfortunately this will not be able to fit to your bike. This is designed to fit to standard 1 1/8" steerer tubes where as the Overdrive 2 headset on your bike features a steerer tube that is 1 1/4" at the top.

Hi, Will The Supernova The Plug Iii Hub Dynamo Powered Charging Device Fit My Thorn Mercury?

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.

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.
