Does anyone know what the internal diameter of the 808 Firecrest CC from 2011 was? For that matter, has the rim changed in that time in any substantial way?
In looking at old Zipp Catalogs from the time, I don't see any internal brake-track width specified, just the outer. The current 808 CC that they sell (not the NSW) lists an internal width of 17mm. But who knows what it was in 2011?


This isn't going to affect my equipment choices. I'm happy with my 2011 wheel. I was just curious.
