Hi all

I am interested in the Zipp 303 Firecrest Tubeless wheels (rim brake version). It's the new 19mm internal width tubeless variety, I am looking at.

Does anyone have real world experience with these wheels - especially the stiffnes (I weigh 76 kgs), braking performance and the longevity of the hubs (I believe these are an update over previous versions with some degree of German engineering as per the website).

Anybody with experience to share?

Thanks

I've got a set. They are a good improvement over the previous gen 303 rim wheels.
Showstopper brake track is good, obviously noisier, but braking is improved. Just make sure pads are flat on and not toed in.
Hub is much better. Clearly better design. No more bearing Freeplay problems.
Wheel stiffness does not appear to be dramatically different, but I'm not exactly a sprinter. I'm a climber.
They came nicely trued and I checked spoke tensions and they were spot on.
I don't use tubeless. I'm running conti 5000 25 width clinchers at 90 PSI.
