Praxis T47 bottom bracket replacement

The cup is the outer race of the bearing. The bearing with lip is pressed into the frame

I need to do something with the bottom bracket of my trek emonda as it has developed some play,

Looking at the cups the bearings look fairly exposed, so can I replace the bearings on their own, or do I need to replace the cups as well?

I've been going through something similar. With a praxis T47.

You can take out the bearings and re-press in for sure but my shell has developed play so I bought a new one and the price difference is not that much between Praxis BB and good bearings. (£50 for BB v £40 for bearings.)

Buy a new BB just to be sure. I actually bought a hope and that developed play over time (play in the shell/frame interface) too so back to the new praxis. (With the Hope I had play on the threads of the BB until its's right in. New praxis no play on the threads). My feeling is my titanium frame threads of gouging at the BB shell threads over time creating play and creaking. It's took me months to figure this out.

Which T47 have you got 30m/28mm or 30mm through. It's very confusing!

Praxis seems a tighter fit from the off.

OP.

If it is the threaded Praxis T47 BB cups ,I have a BB and spare bearings that you can have for free.

I don't have a frame that they fit anymore.

It's press fit on the emonda hence my reply 

I'm talking shite, that was a praxis on a spesh

The t47 uses enduro 2437 bearings for the 24mm Shimano crank (this was ultegra on the domane)
