Permon, this is interesting...looks like Cervelo changes the BB design on the 2012 frames. My 2011 R5 has a completely sealed BB shell...the only hole in it is for the cable guide mount on the underside. It appears your shell is cut out on the inside and access to your chain stays. Indeed the required 13mm contact area is compromised. Huh...I wonder why they changed the design?
