I have on the bike at the moment a PF30 Sram / Truvativ PressFit BB30 (PF30) to BSA Bottom Bracket Adapter and RS500 cups (https://ibb.co/album/jRFSyv)

I want to do an upgrade, (but not go nuts). What would you guys recommend? I like the idea of the screw in cups.

    As a long term user of Press Fit BB bikes I would go for this one:

    Thanks Sandyballs, I've had a look at the Praxis BB and it looks good. As you have used these can you answer one question. I have Di2 cables running through the BB hole and up the various tubes. Is there enough room for these cables and the Praxis? (the cables are 2.5mm dia).

    Praxis themselves say yes:

    However I’ve only used mechanical and so cannot confirm, additionally I suspect different manufacturer give differing amounts of room.

    I've brought a Praxis BB, very impressed with the quality, if I had mechanical gear it would be great, however with the Di2 wires I don't think it will fit, not without mods (cutting holes) to the outer sleeve. I'm told its not structural so it won't be a problem, I was also told by Praxis to cut it in half, mmm. Has anyone else used a Praxis BF30 to BB30 adapter with Di2?
