I have that bike and replaced the BB.

You just need new bearings - search for the type and then whack out the old ones and drift in the new ones. Big hammer time!

Specialized try and make it confusing by calling it OSBB but that frame is a BB30. I have the same frame and upgraded to a Shimano chainset from the original FSA chainset. I fitted the Praxis BB30 to 24mm Converter.

Are the cups specific to Spesh?

Its an odd one, I cleaned and greased everything up and put back together and there is a click/creak. There's no play/wobble in the set up. Any thoughts?

Frame is a standard BB30 so would expect the cups to be standard as well.

i recently dropped my bike off for a service, i mentioned the bb had creaked on my most recent ride, (not a squeak for 17 months), BB had seized solid, took them 2 1/2 hours to cut off the adaptors..

i asked them to fit a BB30 adaptor and now have a threaded 68/73mm BB..

i should really grease it more often :0(

Is your bike the Smartweld version?

Just taken apart and put back together, all seems to be working okay, no clicks yet, but not ridden.

I presume this slides into the space, reducing the diameter and the cups hold it together. It should'nt rotate in the frame?

I also have that bike and fitted the FSA threaded adaptor. No more creaks or clicks. I'm pretty sure the bottom bracket is a normal BB30, but there are 24mm reducers fitted to suit the Tiagra 24mm crank spindle. The bearing points on the crank spindle are offset from the bearing races. If you were designing something to creak, that's how you'd do it.

The FSA adaptor is fairly permanent - it presses into place and is held in by glue (glue may or may not be supplied with the adaptor - the recommended one is some sort of epoxy (can't remember the code number, but it's in the instructions)).

No regrets here, it works very well.

Thanks everyone, I will test it again and see if it creaks, if not its conversion time.
