Hi ,I’m looking at swapping out my torque sensor bottom bracket that’s currently fitted to my Super73 RX . I don’t like the design where the chain wheel spider fits on the bottom bracket via splines as they do not mesh together perfectly and so you get forward and backwards movement.I want to change to a bolt on spider .I’ve found two on AliExpress but one has a middle wire outlet and the other is a side mount wire . I think I need the middle mount wire type if you look where my wire comes out the frame . But the seller says my old unit looks like side mount wire . But is more like an inch in from the end I would think.
Any help would be great .
I’ve included the two AliExpress options and a pic of my old unit plus my frame .
