Brand new take-off wheelset, never ridden. Shimano Freehub body (Sram/Shimano 10/11/12 speed). Center Lock disc rotor mount. Comes with Zipp valve stems.
For too long, the weakest point of Zipp wheels is the hubs. While the newest generation is notably better, they regressed in durability due to the use of j-bend spokes. Zipp did this to allow for easier serviceability as j-bend spokes are sometimes easier to source than straight-pull spokes.However, the j-bend is the weakest part of the spoke and is most prone to failure. That's where the "E" comes in in Zipp 303 SE. It's a Zipp 303 S rim laced to a straight pull Syncros hub (rebranded dt swiss 350). Zipp claims the 303S weights are. Measured weight (using my kitchen scale) of 303 SE with the Shimano freehub body. Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. Road bikes are more versatile than ever, no matter the road surface, but just as fast as before.
The 303 S offers an entirely new rim profile and design to optimize rider performance on this new breed of bike. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S borrows design concepts from the higher-level 303 Firecrest Tubeless Disc-brake wheelset to gain speed through increased efficiency.That is achieved by creating a wheel with reduced: Wind resistance, rolling resistance, rider fatigue, and weight. The key innovation is in the 303 S Series' rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its rim width is 2mm wider, at 27mm, and its tire bed is a full 7mm wider, at 23mm.
That rim platform is designed to be the fastest with a 28mm tire. The wide rim optimizes tire profile to allow lower tire pressure. That helps to reduce rolling resistance and provides a more compliant ride. The result of all this is a 10 percent watt savings vs.A top peer wheel in total power required to ride 40kph on a smooth flat road with a 28mm tire, according to internal Zipp testing. This groundbreaking wheelset also features all-new cosmetics, setting the rider apart from the pack, and comes at an attractive price. Zipp graphics and cosmetic identity that scream speed. Fastest with 28mm, fits wide gravel tires as well. UD fiber / Bake-On labels / Matte clear coat.
