Thank youI'm using Specialized magnet on Shimano: Specialized Turbo Speed Sensor Magnet, Silver | Bikeinn
Probably works fine with Bosch too.
Can you show some pic of that black magic stuff ?Hope that works out for you, let us know. For anyone else with a similar problem to me, I tried the Shimano Lockring with Magnet EW-SS302, for my Cannondale Moterra SL with an EP801, didn't work at all, threw an error so sensor wasn't picking up the magnet whatsoever.
My mechanic ended up just stuffing the 6 bolt magnet in and still using the centre lock wheel and rotor and it works fine. Maybe one of these Bosch or specialised ones could have worked too.
