Winspace Hyper 65 vs 67 Review

[vanillaflyweight]

Very interesting review, I was set on the 67s but now not so sure. Out of interest were you running 23s on both wheelsets? Any issues with the 21mm internal width?

May i ask, talking wheelset like these, let's say 17-21 ID and 28mm OD, deepth about +60 up to 70mm (rim brake), what would you go for?
Talking stability in crosswinds

Yeah I ran GP5000s in 23 on both wheelsets. I would say that you need to be cautious doing it on the 67s because the edge of the rim is just a fraction wider than the tire when the tire is not inflated properly. My rear wheel had an underinflated tire at about 60-70PSI (had a latex tube and I didnt have access to a pump for a couple of days) and I hit a pothole at 50km/h, the rim hit the edge of the pothole and pinch flatted. I would say this is probably what weakened the rim and why it delaminated when a tire lever was used on that spot. In the end I got a crash replacement discount from Winspace and opted to get another set of Hyper65s. I should have gotten a set of 50s!

This is interesting!
I rode Easton Aero 55 tubular. I spoke to Easton which recommended 22-23mm for best aero effect.
The rims were the widest at their time. The brake track is like 28mm and the rims are 30mm at it's widest!
Ok, so i mounted 23mm tubulars and just like you state, the rims walls are wider than the tire.
All good until you hit something, no matter what. If the tire contract at one spot only, and rim wall is actually higher, bang and your rim(s) are dead.
That is exactly what happened to mine.

I didn't even see it at first trying to repair the puncture with sealant.
But the tube inside the tire was demolished around that region (rim damage).
So i would also be cautious using a tire that is not supporting the rim walls.
