New bb?

Hi all 👋

I’ve got a Scott speedster same at the one pictured (not my picture) and I’m wanting to put better components on it as a little project. It’s 10 speed so I’ve put an old ultegra rear mech on it and old ultegra brakes. I would like to put an ultegra front chain ring and crank on it I’ve been putting 6600 on it. So do I need a new bb and if so what am I buying?
Or are there any other alternatives? Been getting everything in a nice shiny silver so matching to that

Thanks guys!
