Hope do a PF41 BB and a Truvativ/SRAM adapter, in both ceramic and stainless options. It’s also made of ally rather than plastic, and the 2 halves screw together, both of which are claimed to prolong bearing life massively.
Been running one for about 700 miles now on my road bike (with a SRAM Red GXP crank) and it’s been faultless. You do need a special tool to fit it, though I’m sure if you buy from your local Hope dealer rather than CRC/Wiggle etc they’d probably fit it for you. If no luck, contact me, I have the tool anyway…
Wheels Manufacturing do various different bearing options of PF41 BB’s too now, and they’re distributed by Madison so any LBS should be able to get hold of one for you. No experience of using one though.
