Guys, would anyone know exaclty what bottom bracket would be fitted to this bike, 2012 Roubaix SL3 Pro?

At some point the cranks will be getting swapped for some Dura ace 9000 series and was going to get one of these to do the conversion. but there are a few different OSBB variants on Spesh road bikes.

I'm no expert but as far as I'm aware the Specialized OSBB is a standard BB30, they just don't like to tell you so you buy a Specialized OSBB crankset.

Can't help with the converter (run a SRAM BB30 on my Spec) it looks fine from the description, sure someone will chime in to offer an alternative that they may have already used.

You need a praxis converter for hollowtec.
I have one if you can't find it. removed with ultegra cranks from my venge when I went sram bb30.
