• The Mavic wrench should have come with your wheels, it's a plastic thingy with 4 pins (or 6?) that engage with the hub cap.
    Once removed, axle off, tap off, tap in. You can build a press out of a threaded rod, two nuts, two washers... very simple.
    If you are in a real spot of bother and Richmond is handy to you, drop me a line.
    ANY shop can do it too
