In designing an upgraded hubset for our pro-proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAM’s development center in Schweinfurt, Germany. The result is the ZR1 hubsets for disc and rim-brake wheels. This hubset features better seal design for improved durability and quicker response with 66 points of engagement. Our engineers spent more than two years developing the ZR1. Proving the durability of the hubset included more than 58,500km of test riding, part of 3,222 hours of total testing. The ZR1 features key technology from Zipp’s Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. At any time, there are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace.

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.
