So, first off let me say I was pretty surprised to find that Specialized calls Campy UT "incompatible" with their carbon OSBB frames. Had no clue when I bought my 2011 S-Works Tarmac SL3 - I had planned to finally 'go Campy' on it, after two decades riding Shimano.
Thanks to a post in the forum, I learned of the C-Bear OSBB adapter, and ordered one from Discount-Bike.de in Germany.
No instructions were included with the adapter. I e-mailed C-Bear for information, but got a response in Flemish(?) about Mavic wheels. Guess I'm on my own!
Here's how it arrived - aluminum BB sleeve, non-drive side cap, Super Record BB cones and C-Bear's ceramic bearings. All new to me - I've been a Shimano guy. A circlip in the 21st century? OK.
I got the frame NIB off Craigslist, but thanks to this dealio from Specialized, I was on my own from the start. So WTH, I'm going Campy
Here's my press. 3/4" threaded rod, whopper washers each side. Spacer sleeve on left is a section of Thomson seatpost I just cut off my mountain rig
Here's the start. I slathered the adapter sleeve in Loc Tite 609. "Medium strength adhesive for cylindrical assemblies" - sounds about right, doesn't it?
But - this was the toughest thing I've pressed by far. Headsets into steel, aluminum - not even close. 200 grain SWC's into .45 cases - easy schmeezy. It popped, it pinged, it took serious pressure. Totally freaked me out. I took the assembly apart probably 6-7 times to ensure everything was aligned. I was certain I was going to hear and feel - at once - the entire BB shell crush under the pressure I was exerting.
Half way in, I knew there was no turning back. As soon as the drive side flange engaged, the pressure increased! I slathered grease on top of the Loc Tite - I needed all the help I could get.
Finally, I got the thing in. Almost. Here's the non-drive side. Tough to tell from the pic, but it is flush and even with the carbon BB pipe in the frame.
But here's the drive side. Still a ways to go - and hard to tell if its aligned or not.
At this point, there's no gap left for the press to press against. I wailed away with a rubber mallet, but the adapter would no sink any further. So - I think its going to remain here. Not coming out, that's for sure. Triple checked the BB shell, scanning for damage or cracks, all looks good. Now, to wait for my Chorus group to fly in from Ireland.
