SPEED FOR ALL ROADS AHEAD
Zipp’s 303 S Series 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 is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. The 303 S Series 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.

I recently took my dated and tired old racing bike along to Leeli Cycles for some much needed work. I was cheerfully greeted by Ben the very friendly owner and number one mechanic. He suggested a full service and looked over the bike to access the condition of the other cycle components. A very comprehensive quote was later emailed to me listing all the parts that Ben would require to complete the job. He phoned me as soon as my bike was ready and I hurried along to pick it up. My first reaction was, wow! It looked as good as new and fully roadworthy again. Ben had done an incredible job in transforming my old racer back to its former glory! I'm very pleased to have used Leeli Cycles along with Ben's wealth of mechanical knowledge, sound advice and attention to detail. Even happier still to support this amazing small local business offering great value and excellent customer service. An outstanding shop in every way for all your cycling needs with the personal touch. Pop in and see for yourself. I guarantee you won't be dissapointed.
