08/2014: "Have had three months (and four replacement sets of BB bearings) on my 2013/2014 PRO SL4 OSBB, with Ultegra 11-spd cranks. Your chart seems to indicate that there is no adapter (30mm to 24mm) in your setup. If so, what bearings are used as they cannot be the usual 6806 which have an ID of 30mm, as you would need an ID of 24mm. This would suggest a bearing OD of much less than 42mm, and the only ones that come to mind are 2437 with an ID of 24mm and an OD of 37mm, so what do we do with the other 9mm of the ID for the OSBB shell?"

C-Bear: "2013/2014 PRO SL4 OSBB 42mm bottom bracket shell. The bb is a set of precision cnc alum. bb cups which have a 42mm outside diameter. 24id bearing sits in this housing. So just press in C-Bear BB30-24 bb into the frame, then fit your 24 Shimano crank. That is all. Simple, no adds-on, no loctite.
