Right, electrics is not my thing, that's my starting point.
Managed to attach B&M light to the 'bent, that's mechanical, I can do that from a raid on the bits and pieces box.
Run the lighting cable along the boom and down the inside of the fork, no problem, plenty spare.
When it comes to the USB werk, if I put it inside the frame bag as I always intended, the wires are too short to get to the hub. I have excess from the light which will make up the difference.
QUESTION - (probably for Kim) - what is the best way to join those bits of the wires, or is relocating the usb-werk the best plan? I'd like it inside the boom-bag for neatness mainly
