WhyFi curious about your thoughts.

Challenge lists their Strada Bianca Pro as hookless compatible in 33 and up. Enve lists the 30 as approved on their 25 wide SES AR. Wondering if you’d trust it or stick with what the manufacturer says. Since Zipp doesn’t test- I’m thinking I can trust the 30, but who knows.

I imagine that the 33 is about as fast as the GP5k 32 since the 36 is only like a watt slower. I’m probably over thinking it.

Also- I don’t know if you’ve used the Rapha down size, but if you do, you can use the jersey discount on the bundles. I got some core cargo bibs and a core lightweight jersey for 120 bucks.
