BRIDGE SCALPEL 29 CARBON
Took me two minutes to find that...
That is it! It's called a bridge...interesting because Cannondale doesn't even have a part number for that.
Appreciate your help N.T
I too needed a new bridge a while back, and Cdale lead time was two months. That site is also where I found mine, and is the ONLY place I could find it 6 mos ago. Although they only had white which looks funny on my ultimate, it did get from Germany to Texas in 10 days, was so happy to get the bike back on the trail.
