Hi there, got a Fuji Sl 2.3 PF30 frame, today i sent it to a LBS so they could remove the factory BB (praxiswork pf30->GXP conversor) and install a Zrace PF30 Dub BB. this because i recently bought a sigeyi PM and it was a combo including crankset and BB (all DUB).

problem is when i went to pick up the bike they said the PF30 Dub BB didnt fit completly in. the non drive side of the BB was out by 1.5mm aprox. they said the BB just didnt go further in, and also that if given small hits the extra space could be moved to either the drive or non drive side. i got worried but just took the bike home. after a short test ride and arriving home i realized the free space originally on the non drive side had moved to the drive side.
now im even more worried.

is this dangerous? or does this happen sometimes? is it just a bad installation or maybe the zrace BB is faulty?
i know using a zrace BB aint the best thing, but the plan was to use it for a while to test the PM, on a near future chainging the whole crankset is the plan (and quite possibly with new BB. in any case i gave the crankset some small hits to see if the BB moves easily to the other side and it doesnt seem so. i think it will stay where it is now. still worrying. thanks for any help im quite lost. (and need to go back to training soon).

edit: sadly as new member here im not allowed to post pics nor links,
only way i can imagine of sharing an image of this is is if you go to : i.4cdn. org/n/ 1639792591195.jpg
and remove spaces, hope this works, hope no one gets mad, im just seeking help (and a bit ultra worried, first expensive bike btw)

I don’t think it is dangerous, as in you will experience a catastrophic failure. But, if the BB is moving back and forth laterally in the shell, that means it could also rotate in the shell. My question is how did they install the crank? The way it is designed, I just can’t wrap my head around how they were able to properly install the crank. There is a pre-load collar that is used to take up a small amount of play that exists by design when the crank spindle is properly torqued, but of the 3 DUB cranksets I’ve installed recently, the amount of play with a properly installed SRAM BB left about 0.5mm max.

The pictures of that bottom bracket on AliExpress show spacers included with the bottom bracket. Did the shop install the spacers?
