Torque wrench recommendations

You can pass an extension through the centre to tighten left-hand threaded cups with a clockwise motion. For pedals, it depends what tool interface you have - 8mm hex socket in the back and 15mm flats on the front means you just need a crow's foot to do the one which is right-hand threaded. If you only have flats, the crow's foot needs to be long enough for an extension to pass the crank from the back. If you only have hex sockets, then you actually need a torque wrench which works both ways 🙂🙃
