Brucey is correct, as always. The Edelux is on a mount that replaces the skewer nut.Brucey wrote: ↑23 Jan 2024, 4:57pm I think that is a set-up I've seen before on stateside road bikes; there is a hub dynamo just driving a front light, which is attached to the front wheel axle. The whole lot comes off together. This is ok if you don't mind your lamp being low down and the inevitable wheel shadow. In addition, it is almost certainly on the wrong side of the bike, when you are on the RHS of the road.
Makes it easy to move the dymo+lamp from bike to bike.
The low mount works well with a Edelux or B&M light, not so good with a round beam light.
