[kwantani]

newbie Q: I've a new frameset that has T47 BB spec. My current bike is running Aliexpress Riro carbon road crankset (3 pieces), will it works?

I just need a new T47 BB? correct?

Yes. If your crankset is 24mm spindle, you need T47 BB with 24mm bearings (or reducer) to make it compatible with your crank. If you search Wheels mgf and others have T47 BBs for virtually any crankset spindle size. The other thing to note is there are two standards for T47 -inboard and outboard. If your bike's BB shell is 68/73mm you need T47 outboard with 24mm bearings. If your BB shell is 86.5mm you need T47 inboard with 24mm bearings.

If your crankset is 29mm spindle, you need T47 for DUB with rest of the things remaining the same as above.

E.g. WM T47 BB for 24mm spindle and 68mm shell : https://wheelsmfg.com/bottom-brackets/t47/t47-outboard-angular-contact-bb-for-24mm-shimano-cranks-black.html
