Praxis m30 bb - what external cup tool do I need?
Removing my Praxis Works M30 bottom bracket from a Specialized Tarmac and want to know what tool I need to take off the external cups. Searching around yielded the "Praxis M30 Bottom Bracket Tool" (conveniently not in stock in the US) or the "Park Tool BT-79". The BT-79 Park Tool webpage doesn't list the M30 but does say "and more" in the list of compatible bottom brackets. I'm measuring the Praxis at 46mm which matches with the BT-79 but I'm not sure if the notches will line up - the M30 actually only has 6 full notches and 4 half-notches and smooth sides. Ideally I'll get a tool that I can use on some other BBs in the future as I'm swapping out to another type. Thanks everyone!

Annoyingly it is their own and as far as I'm aware not used with any other BB. Looks like Praxis direct has them in stock.

Thanks for the reply, it looks like you're right. The M30 BB measures 46mm on the smooth sections/bottom of the notches but is 48mm at the tops of the notches/widest part (if that made any sense). Going to email Praxis just to check.
