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 a redesigned 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 is among Zipp's lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. The key innovation is in the 303 S's rim design. Its 45mm rim depth is the same as its predecessor, the 302 Disc brake. But its external rim width is 2mm wider, at 27mm, and its tire bed is a full 7mm wider, at 23mm internal width. 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 watt savings vs. a top peer wheel in total power required to ride 40kph on a flat road with a 28mm tire, according to internal Zipp testing. This groundbreaking wheelset also Specifications updated cosmetics, setting the rider apart from the pack, and comes at an attractive price.

- Wide hookless rims create a seamless transition to the tire, reducing drag
- 76 / 176 DB hubs with center locking interface
- XDR driver body option

Bicycles, Trainer Bikes & Indoor Trainers
Clothing, Footwear, Helmets & Protective Equipment
These items are subject to our policies above, with special consideration for fit. A lot of our brands offer comfort guarantees. Bicicletta and our brands are selective when it comes to utilizing these warranties as it means the product you return will be destroyed. If you’re at all unsure of how an item fits, or if sizing is confusing, please reach out to Rider Support. We can help guide you through choosing a size and make alternative considerations to help make sure there are no regrets. If you need to order two sizes of a product to try them out, it’s totally okay to return what doesn’t fit. However, potential abuse of this policy will be monitored. Ordering many pairs of shoes to try them all on is wasteful, so let’s not do that. Instead, chat with us beforehand to find the best fit.
It’s hard to find the right saddle, especially online. We understand this entirely. You’re free to order 1-3 at a time to try them out. We ask that you place electrical or masking tape on the rails to keep them clean for the next customer in case you need to return. Saddles often come with comfort guarantees too, so feel free to inquire about whether the brand you’re looking at does or not. We’ll often try to avoid doing this as well because we don’t like to be wasteful, but if you use tape and don’t take it on an epic shred down a mountain, chances are they’ll be fully re-sellable and we can refund you for it.
