Zipp303 Firecrest Tubeless Disc Brake Wheels(Return to Product Page)

I like the wider internal width and has a better feel than my 19" internal width wheel.

I only put 200 miles and I'm thinking it still need at least 500 miles of break-in, but the hub can use some improvement. The ZR1 DB hub does spin nice and quiet, but not as good as my Campy WTO that this replaces. Did wish BikeTiresDirect had the Chris King hub option and there won't be any question. But, will wait for a few more miles before a full review.

Overall, I still love this wheel, but will find out in another few miles if I end up replacing the hub.

Great wheels! I owned the 2018 Zipp NSW's and always like the ride, fast and sure footed. I bought a new bike in 2022 with Enve Foundation 45's. I liked those, but for me, they were a much firmer harsher ride than my NSW's(and a tad slower than the new FC 303's). I didn't want to break the bank so I replaced the Enve's with the Zipp's 303 FC. The 2023 FC are also softer than the 2018 NSW's. I run new Zipp 303 FC according the their recommendations which is in the 50's for tire pressure. In May of 24 my rear wheel cracked while riding in a city with too many potholes. The reason I gave it 4 stars. They sent me a new or refurbished wheel, but it took about 2 months from the day is cracked. BTD helped me through the return process no problems.
