I made initial plans to get a custom replacement for the spacer where the speed sensor used to be. However, after it was priced up it made little sense to get it for the moment when there are more crucial parts to acquire, so I refurbished a 10 quid speed sensor with clean, acid etch and chip resistance black paint – look mega, postions the wheel perfectly, and covers the new bearing set a treat. Will get a cap for thread and will live with it for now. Later down the line I will revisit small compromises like this once it is all up and running.
