The number to count on—240 with Ratchet EXP. The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement (which reduces wear), and a smaller number of parts not only makes maintenance easier, but also reduces weight.

Dependable Independence – Reliability, versatility, and simplicity are united in a hub. Thanks to the proven freehub Ratchet System, the 350 hub is a dependable partner for every adventure. The 36-tooth ratchets ensure direct power transmission. The sophisticated yet simple construction of the hub allows a low weight while providing outstanding rolling performance. Furthermore, it enables cyclists not only to maintain their freehub system without special tools but also to convert to the various standards. The intention behind the 350 was to create a dependable hub that supports cyclists in their independence. PRODUCT DETAILS: - A DEPENDABLE HUB The freehub Ratchet System makes the 350 the dependable partner for any ride - NO TOOL CONCEPT Plug-in hub construction allows for quick and tool-free maintenance - NEW ENDCAPS The new shape of the end caps facilitates disassembly and thus speeds up handling requiring disassembly - VARIETY The 350 hub is available for all common axle standards and for the various drivetrain systems. TECHNOLOGY: We believe in the art of engineering and strive for sophistication in the product development process. Our guiding idea is to constantly push barriers with our in-house developed technologies. LEGENDARY RELIABILITY: The patented freewheel system, which features high-precision star ratchets, guarantees top performance and reliability. The simultaneous engagement of the ratchet teeth makes the Ratchet System extremely reliable since the loads are distributed equally across a large contact surface.

The new standard for durability and price. - Contact-free seals and high precision build guarantee smooth bearings

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 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. 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. - Better sealing, increasing durability over previous hub model - Quick engagement for a responsive ride - Lightweight - Same bearing size as premium-level Cognition hub - e-bike certified - Disc brake hub with Center Lock rotor interface. The lock ring is included
