They look like they are meant to be a competitor to the Cadex 50 Ultra but are priced about a grand less
That was the first thing that jumped out to me as well. An internal of 21 is perfectly fine. But with the external being just under 28mm, you are probably stuck running 25mm tires if you want to maximize their aerodynamics. A tire labeled at 28mm is probably going to measure out to 29+mm on them.
The thing with broad external width is that some frames don‘t have the clearance for this. Sadly my beloved road bike has a clearance of 30mm which is just not enough for the Roval Rapides.
Obviously the solution is to get these wheels for your current bike, and another bike with slightly wider wheels. So you can compare them. For science, and stuff.
Those are really good. Swiss Side’s involvement = good stuff.
I would have gone with DT Swiss hubs but went with Carbon-Ti for the weight savings. The 180s were close but for a lot more money.
Just beware of shipping times. Hopefully they have improved but it took about 10 weeks for me to get my wheels from order to delivery, and most of that time was spent in transit - literally a slow boat from China.
I wouldn’t call winspace wheels an off brand anymore I think they are established now. The question is do you have a dealer distributor in your area for that kind of money that would be a piece of mind else all the warranty and service stuff could be bothersome.
And for the weight they play in the enve ses 4.5. Space but are 100g. Lighter.
I’d argue the only thing zipp/enve have on winspace is the dealer network for service and warranty and winspace is expanding a lot there.
