2019, Zipp, 303 NSW Carbon Clincher Tubeless

Zipp has made many important contributions to the advancement of focusing on aerodynamics in cycling. It seems amazing to think now, but up until the early 2000s, just about every frame had round tubing with box section rim wheels. The Zipp 303 NSW rim brake wheels are the latest installment proving Zipp’s dedication to creating the fastest, most stable wheels available.

The NSW are the top range for Zipp road wheels, and this time they have tweaked them to accommodate a modern setup. That means that the rims have a wider 19mm internal width compared to previous editions. This change has aerodynamically optimized the outer rim width for 25mm tires. You could conceivably put something wider on them, but remembering this is a rim brake wheel, you’ll likely be more limited by how much tire volume the brakes can accommodate than the rim width. These are racing wheels first and foremost, after all.

This wheelset allows you to run tubeless or traditional clinchers. Tubeless tires offer a number of advantages over clinchers such as low rolling resistance, overall weight savings, superior flat protection, the ability to run lower pressures. You’ll be impressed also with the ride quality and cornering capabilities tubeless tires offer: all the advantages of tubulars without the hassle of gluing them on.

The 303 NSWs use the Zipp Cognition hub set that uses magnets to engage and disengage the ratchet mechanism. The Axial Clutch technology Zipp has developed reduces the drag of a traditional spring mechanism by disengaging the ratchet completely when coasting. Saving that energy loss due to friction will give you a refund on your real speed that you can take to the bank.

With the 45mm rim depth, these 303s offer you the best of aerodynamic advantage with a minimum of weight and will remain beautifully stable in cross winds. The updated Sawtooth design has the dimples forming the sawtooth shape to benefit the wheel’s performance in the wind. And once you get everything going nice and fast, you can feel confident that the braking performance will be excellent as well thanks to the Showstopper brake track. Rain or shine, it will offer solid stopping when you really need it.

The refined carbon layup of the Zipp 303 NSW wheels ensures they are durable enough to be your go-to training wheels, and light enough for race day. The front wheel has 18 spokes in a radial pattern while the rear comes with 24 spokes in 2 cross pattern both on the drive and non-drive side. Zipp does recommended a rider weight limit of 250 pounds. A set of Zipp 303 NSW wheels weigh 1500g with the front weighing 675g and rear comes in at 825.
