I had the same issue just a month ago. The plastic sleeve just didn't want to come out. I ended up calling Praxis, the guy on the phone said this was a common thing and recommended cutting the sleeve out. Apparently they even sell replacement ones at their site for $8 (which I did not check.)
Cutting that sleeve was not that easy (I did not want to get to the frame.) it took me over two hours but it is out.

Received the RT-2 tool today and it took about 40 seconds to remove the praxis PF sleeve. It was certainly worth the investment. Thanks for all your help and advice.

The Praxis design is just not very clever in this age of internal cabling and wiring. And lots of BB shells also have internal features, like the end of a bolt poking through, that can get in the way of fitting.

Fortunately ... lots of alternatives out there which do not have the expanding collet. And which are also a lot easier to remove; requiring no special removal tool.

Hi, I have a praxis sleeve stuck in my bb. I removed the two internal pieces easily with a bb tool and headset tool. But now the sleeve is stuck. It is flush with the frame so a bb tool will not lodge on it. Any ideas how to remove the sleeve in one piece? Many thanks

Thank you. Is it possible to remove without cutting out?

I found a washer almost the exact size but fractionally smaller than the diameter of the sleeve. Some slight hammering and the sleeve came out.

Old mountain bike handlebars or even 1/2" or 3/4" PVC pipe sections work far better than screwdrivers if you don't have the real deal tool.

Thanks for all replies. I was hoping I could find an elegant solution but eventually found a marginally undersized round plastic disc (45mm I think) and bashed it out in one piece. I am refitting internal cables then will see if it is reusable!
