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.

Zipp's ZM2 hubset delivers dependable precision performance to the gnarliest trail. - Engineered in Germany with better seal design for improved durability - Compatible with e-mountain bikes - Spoke Count: 32H - Boost only - 6-bolt brake interface

Zipp's ZM2 hubset delivers dependable precision performance to the gnarliest trail. This German-engineered hubset features 12 pawls and 132 points of engagement for a quicker response. The hub's improved seal design means better durability on rough terrain. The genius of the ZM2 hub is how we achieved quicker engagement. This hub system works with 12 pawls, in 4 groups of 3, on a 33-tooth ratchet ring. The 33 teeth make the ring strong with pickup that's reliable and consistent. The 4 groups of 3 pawls are staggered, meaning there are always 3 pawls engaging at any time, which boosts durability. The ZM2 also has higher load transmission capability. The hub is capable of being used on electric mountain bikes. - Engineered in Germany with better seal design for improved durability - 132 points of engagement - Designed with 12 pawls (4 groups of 3) for quick engagement - Strong ratchet ring maximizes load capacity - Compatible with e-mountain bikes - Spoke Count: 32h - Boost only - 6-bolt brake interface

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

When we first introduced our Wacky One-Speed Rear Device (W.O.R.D.), it was the first purpose-built single speed mountain bike hub. That original hub not only set design standards that continue to this day, like a 52mm single speed chainline, it also proved that small American manufacturers could stand out in a market increasingly crowded by bigger overseas brands. When designing this modern version of the WORD, we spread the flanges out as far as possible while leaving room for freewheel threading. This allows the WORD to be built up as a strong dishless wheel. Over the years we’ve also improved upon the original axle and bearing adjustment mechanism to produce a single speed hub that we’re proud to call one of our heritage - 6061 Aluminum - 200g - Anodized or Polished - Black or Silver - Axle Spacing: 135mm - Flange Diameter: 43m - Center to Flange: 39.5mm - Chainline: 52mm - Spoke Holes 28, 32, or 36 - Freewheel threading English 1.37x24tpi - Axle Bolt Torque 21 N·m
