    Bearing press tool, I would take it to your LBS to have it pressed unless you plan on doing lots in future as itll be a one off tool.

    Well the image in the link above clearly states "press in" on the drive side bearing. However the central section also carries the text " Center shell with threaded lock on design".

    So I'm guessing you need to press the drive side in then use a specific tool to screw the non-drive side bearing into the central shell.

    You need to check the number of notches on the non- drive side bearing as well as it's diameter. Park Tools do a number of tools for differing notch counts and diameters. For example

    The above may not fit your BB but it gives you an idea of what to look for.

    I've fitted a similar one from Token (suits Trek "press fit" BB's as found on Domane's in my case). You don't really have to press fit one side before threading them together, just fit insert both halves, noting which is the drive side, and hand screw them together until they go tight. Then it's a case of the appropriate tool to tighten one side. That'll pull both halves into the BB shell. Do please observe any torque specs as it's quite easy to keep tightening them and deform/crush the BB shell on a CF bike. Oh, and grease the frame "cups" and the BB threads before assembly.
