Thats the fix we need!!
Hi all,
Doing a carbon wheelset with centrelock hubs upgrade and have fitted a Shimano RT-EM810 rotor which is one of the EMTB rotor(Shimano Steps mind you) with the fitted magnet.
All fits perfectly but I'm having issues with random power loss.
I know its to do with the new rotor as I fitted...
