My CX bike has a bottom bracket that looks like this:

It is marked “GXP >PA+GF<“ and then a little triangle.

Crankset is SRAM Force 2.2 (circa 2013)

So I’m guessing by that, and by the fact it is knackered and creaky, that it is probably a Pressfit BB86/83  Does that sound right?

If so any advice on what I should replace it with? Is it worth converting to Hope or something else a bit more durable and a bit less squeaky? Or just stick with the cheaper like-for-like option?

Might be as easy if you tell us what the CX bike is

It’s a Rose Pro DX Cross 4400.

(Note: It’s not used for actual CX. But it copes well on the mud and potholes of my local paths while still being svelte enough for a decent road ride).

creaky doesn’t always mean knackered

What you said a PressFit BB86 (like this )

I’d just get the same a stick some extra grease in. My old Cannondale crosser had a pressfit that started squeaking, I just opened it up and greased it. My mate has the bike now and the BB is still running fine 4 years later.

So is it one of these?

Because that one looks right but says “MTB” on it, which is confusing.

Are there different road and MTB versions?

(Oh for the simpler days of a threaded UN72 that didn’t need special tools and lasted 5 uncomplaining years with zero maintenance)

GXP pressfit, MTB is 92, road is 86 and there is a Specialized 84.5

Thanks @bigyan, I’m guessing wiggle just mixed up the image then.
