They look a lot like the old Zipp 101s

Which I had a pair of way back in 2009. They made my Allez look very pretty, but I doubt there was much advantage over the original Mavic CXP-22 rims, which are back on it now.

"...the street finds its own uses for things"

But wait...I thought that designing rims for rim braking REQUIRED the brake tracks to be straight up and down!...at least that's what all the "separate braking surface" folks tell us :-/

I'm intrigued by the ceramic coated rim-only option. I wonder if these will be available before HED finally starts selling the Belgium Plus Black rims...

I have ceramic on my (retro) mtb :



Almost as loud as the carbon on the tri bike :-)

Yup...to be honest, I really like the "radially machined" surfaces on the Hed rims. Even with just regular anodizing on them (technically a "ceramic coating") they work REALLY well.

These are significantly deeper.

Yep, 2.5mm deeper.

But at $1300, the 101s were a lot more expensive and weighed a bit more, iirc.
