Hi, I'm looking to upgrade, at some point, to wheels with Hope hubs and Hope brakes.
What options are there for holding the magnet in position? and how critical is the positioning of the magnet in relation to the sensor?
Currently I have Magura centre lock floating rotor that has a dedicated position for the magnet to be fitted.

Hi,
cant you just use the shimano disc with the built in magnet?
Otherwise you can glue a magnet to another disc, the distance is important
if that is too far you will get Errors.

Sensor is pretty critical, i've had problems with the sensor on the outer limits, now it's about 11 mm and straight on the marking and working fine now for over 10k.

On your picture looks like the magnet is not in line with the marking.
