Now what I'm not fully understanding is the amount of cup engagement on the DS. The BBright shell may only offer 13mm of engagement (see drawing) which would appear to match the Campy adapter, so I don't see where the "3 times more" engagement is coming from.
Thank You for the drawing of BBright BB! It helps a lot!
Your question regarding the 3times more contact area. I measured Campa BBright cup, actually the contact surface on the cup is ONLY 4mm long!!!!!!!!
So, 13mm available in BB is 3times more
I made a quick draft of my idea, see bellow. I think that it could work quite well using an ordinary BSA right cup + my adapter.
I have already contacted Cervelo and they told to send my frame back. I do not want to do it because:
1) I am quite sure I will have the same problem with a new one (using campa cups)
2) I do not want to spent my time stripping and re-assembeling the frame again
3) I am sooo afraid of getting back the HORRIBLE 2013 Silver paitjob. I love the 2012 black/red
So, I am going to try this machineshop adaptor first, if it does not work, I will send the frame out.
Guys, what do you think about all of this?
