What bottom bracket i need?

[Peet30]

Hey guys!

Im not exactly sure what bottom bracket i need. I have the 2023 orbea orca and now the FSA B3155 is installed.

Would the shimano SM-BB92-41B fit? Or can i only use bottom brackets with 46mm?

Greetings
Peter

I thought I should reply as you've had no response as yet. I'm no expert.
It's a pressfit. The governing factor is the spindle diameter. I believe all pressfit shells are 86mm.
Shimano spindle diameter is 24mm. What is FSA?

No.

Yours is the PF30 standard, which means it is designed for 30mm crank axles. The shimano ones are designed for 24mm crank axles.

You should be able to use any PF30 BB, provided it is the right length (depending on road or MTB)

Thanks for your reply guys!

FSA is the brand. PF30 or BB386EVO should work. Yes maybe they are designed for 30mm crank axles but i use them with adapters so the 24mm crank axle fits in.

Ok, if you have 24mm cranks, then the BB86 or BB92 should work. The shell size is the same.
