I am considering changing the cranks on my Tarmac to the SiSL2 cranks.

Couple of questions:
1. Compatibility issues? I am assuming that SPesh's PF30 BB is pretty much the same as Cannondale's BB30 BB...but just wanted to make sure that I won't run into any unforeseen issues.

2. Has anyone seen a Tarmac with the SiSl2 installed? I googled that but did not come up with any images. Maybe it's a no no to have cannondale's cranks on a Specialized?!?! I guess I can always cover up the Cannondale wording with a crankskin protector.

Thank you for the reply. I am pretty certain that my Tarmac has a "pure" PF 68 mm wide BB with the aluminum insert.

As for installation, bringing her into my LBS to do the job. Love tinkering with my bike but haven't felt confident enough to mess around with the cranks / BB.
