I ride a Specialized S-works sl4 Tarmac. It has a BB30 bottom bracket. See the picture.
Which Praxis Works ConV BB do I need to use my frame with the Campagnolo Ultra Torque crankset (2015 model).
I bought the BB/PF30 ConvBB Campy ULT 68mm Road but I am not sure if it is the correct unit when I look at the pictures and the Praxis works video on you tube. Can you help me out?
Thanks in advance!

On the pull down tab there is an option for Specialized OSBB.

So you think I need the OSBB version? What is different between the OSBB and the BB30 version. My frame is BB30.

Are those inserts glued in? I am not sure but my frame came with these inserts pre installed.

So if I understand you right, I need to remove the inserts on the picture and replace them with the Delrin cups that are delivered with the OSBB version praxis Works (http://www.praxiscycles.com/product/conv-bb-campagnolo/).

Are those Delrin cups glued in or are they fixated when the Convv BB is pressed in. I don't want friction and noises from the bottom bracket when cycling (my worst nightmare

You won't have that with praxis. Just follow the instructions on the praxis site and you will be fine. They are initially pressed in, but I believe the nature of the praxis is that the collet system expands and holds them.

Ok thanks. Final question. The delrin cups on the picture are pressed in by Specialized. I am not sure but I believe the frame came in with theses Delrin cups pressed in. Can I remove them savely or are they glued in the bottom bracket. I assume I need a Partool bracket removal tool and a soft hammer to do it?
