Hi everyone - I have searched on previous topics, but couldn't find an answer for this:
I need to get new (headset) bearings for a Cannondale System six.


I believe the top bearing is 1 1/8 45x45, but what are the exact specs for the bottom bearing?

The FSA 1.5" bearing 90d shoulder MR069 seems to be what I need, but I just want to be 100% sure.
Will the bearings of a FSA Orbit C-40 headset fit fine?


Any help is appreciated - thank you!

This is the headset that you need. How do I know this because I have a sytemsix with this exact headset. Don't waste your time trying to find something that does not work. http://www.cannondaleexperts.com/Cannon ... p_229.html

Thanks for your reply.
Yes indeed the original Cannondale headset would fit fine, but I don't need a complete headset, just the bearings.


The FSA 1.5" bearing seems to be a close match - bearing I.D. and O.D. are the same, I just wanted to confirm.

I called Cannondale and they said the lower bearing has a 52mm OD and is 45/45 angular contact bearing.

I'm going to order the Cf-40 and hoping that it'll work with the Easton SL Taper fork.
