Sucks! I'm not touching pressfit again after this frame. The whole reason for me using this frame was to build a reliable bike. I hope the KCNC bb Thrust ordered fits. Seems like a bb that threads into itself is neccessary for it to stay in place. Hope has a version too but i don't feel like shelling out £100 for a bb..
psee-
It shouldnt be of concern as the BSA adapter should work with any threaded bb made for that type really but I feel like it could be a SRAM gxp only problem. As the new gxp brackets have a kind of limiter inside the nds cup. Meaning that the cup limits the spindle from getting through completely to ensure that the crank does not rub against the drive side bb cup (I hope any one gets where I am going). As you screw the nds crankarm on to the spindle you apply force that may eventually lead the whole adapter/cups/spindle bricolage to shift in place. Through the limiter, the spindle pushes out the whole bb cup and adapter on the nds and the driveside crankarm all of a sudden sits closer to the driveside cup causing (in my case) chainring bolts to rub. Should not be of concern with shimano I recon as you only preload spindle on nds side with the little plastic screw thingy and then clamp the nds crankarm. Also, hollowtech 2 bb does not have some sort of stupid limiter built in..... dont know - PF30 sucks! This frame with 27,2mm seatpost inner and threaded bb would be a dream! cheers

They sent the wrong colour, so it'll take a few more days :/
Which other bottom bracket you think would work? Praxis didn't fit as I mentioned above.

Sorry, I forgot about the pic until I did a ride on friday. noticed some rubbing coming from the crank/bb area. chainring bolts were rubbing on the driveside chainstay because the limiter of the gxp bb could not hold the spindle back and in its place (hope that makes sense). It turned out the nds of the sram adapter was pushed out a little. pushed it back in (with tools) and everything is in its place again but cant tell if it stays there as I havent been able to test it afterwards. Just wanted to confirm your issue with loose cup!
