BB386 EVO Cranks, what BB do I need?

one of my BB bearings is getting crunchy, I need to pop out the bottom bracket shell and bearings but I'm a bit confused about which one to get. It's an 86mm width frame and uses the SLK ABS BB386 cranks. So what type of BB? PF30? or is there a specifc fsa one I need. Bike is a Bianchi Oltre XR1 with PF86 I believe
Thanks

You say the frame is PF86 so you need a PF86 EVO BB.

Thanks, it's hard to believe there is only one option for this. Couldn't find any other sources. I could only find this on FSA webstie:

Press fit is the limiting factor.. You may not have access to using alternate bearings,,.. from industrial sources..

why cant you just ride what you have?

It appears to accommodate the big hollow tube designs so much in vogue now , [looked at your FSA link]

they apparently, use a pair of double row bearings with many small ball bearings.. seems an OK design.

The factory machined the frame for the bearing assembly they would use..

really want something else? buy a new bike which the manufacturer chose that kind you want, as well...

Enduro makes a Torqtite bottom bracket for that application. It does not need to be pressed but screws together.

It's a FSA designed BB standard so not really surprising.
