Hi
I've cracked my front da c50 rim on the braking surface so new rim, I've found a replacement rim its not dura ace but it's a 50mm 16 hole rim with similar aesthetics will or should I be able to rebuild the wheel using existing hub and spokes?

All measurements seem to say so, pretty much identical rim, just slightly different rim width the original Dura Ace rim measures 20.8 and the rim I've sourced is 20.5, will this make a difference?

Just want to be 100% before I do anything

Cheers

Width of the rim doesn't matter when it comes to building it up: the diameter does.
