My frame uses a 41.8mm top bearing, would a 45 fit this
Maybe, depends on the wall thickness of the head tube. Take a measurement, I have all sizes from 45 to 48 in stock.
Any idea what size for cannondale caad 5?
I'd guess at 47×2 given that subsequent generations are that size, but there's no substitute for doing your own measurement.
