Rim on the Boras is pretty light for a 50mm rim also. Factor in the giant stickers and the difference is less than you might think
If you compare a set of Neutrons to the Hyperons you'll notice that they're exactly the same bar for the carbon rims of the Hyperons. I.e. fatter spokes on the driveside of the rear wheel and the exact same number of spokes all in all as well.
IMO, given the far greater stiffness of the carbon rim, they (Campa) could have done away with at least four spokes on the FW. Instead of this rather silly cross driveside/radial non driveside configuration of the rear spoke pattern they could also have reduced the spoke count and opt for a more clever pattern such as 2:1 as used on the Fulcrum version.
That would have shaved at least 40g off the Hyperons without compromising stiffness IMHO.
Interesting ... wld love Mr Campagnolo to come out with something along those lines:
- 16 spokes F, 24 max R
- 30 mm ish depth, wide smooth rim shape
- carbon hubshells, CULT bearings
