I’m not sure that 150g savings is really a worthwhile thing to chase for most riders. Sure it probably makes a difference, but probably not be worth the cost. I think a lot of these products only exist because consumers are willing to pay for them and think “if I want to climb well I need a climbing bike and climbing wheels”. If your wheels are already using good hubs and quality rims with a good brake surface (presuming rim brake here) I wouldn’t bother going through the trouble
If you have them, why don’t you just weigh them?
Also, they are 1510g (https://youtu.be/4gpjH4hvAMU).
Aero wheels are basically always faster. 150g or even 250g on wheels is negligible unless you want a bike to flex on the weight weenies or you are at a point of your physique, where loosing 250g of body weight severely lowers your performance.
I think there have been a couple of podcasts that were basically like, weight savings dont’ matter as much as a lot of people think and “rotating weight” doesn’t matter as much as wheel manufacturers claim.
So if they’re light enough, they roll good, and they handle good, you’ll be all set. I certainly wouldnt’ sweat over 150g difference for the set.
