Looking for a nutted derailleur hanger but not sure about sizes etc

I'm going to be converting my Mafia Blackjack to geared as it's going to be used as more of a general riding bike, I'm using a Hope Pro 4 rear hub with a 10mm female axle, would anybody be able to send a link to an appropriate bolted/nutted derailleur hanger or tell me exactly what I would need to look for as there is loads of random options, thanks.

And we will do this consulting/design work with no photos of more info? BTW what's a female axle? The axles I see are more male like in shape

Really projects like this have no script and instead depend on the ability to fabricate, design or have a supply of various bits to get the creative juices going. Dropout shape and hanger interfacing can be all over the board. Do you have a LBS with hangers on hand to take your bike to and rummage through their options? Andy

I'm not currently home to add pictures so I was hoping somebody who knows the frame would know, if not I'll add some soon. And by female axle I mean where the bolt screws into the axle as opposed to the male where the bolt goes over the axle lol, but thanks for reading anyway, if not I'll email mafia and see if they have any ideas.

The current Blackjack D has rear dropouts that look like trackends to me: short horizontal and rear opening. Perhaps the Problem Solvers chain tensioner with hanger would be a nice option for you: https://problemsolversbike.com/produ...hain_tensioner .

Again dude, get a proper mountain bike. This was not meant for gears it is designed as a dirt jumper which doesn't have or need gears.

Here you go, a Shimano RD-TY500 rear derailleur with a rear-facing claw mount, for track-style dropouts. Although I doubt your dropouts are long enough to hold it securely. There really isn't enough real estate on your dropout to hold both a derailleur and a wheel.
