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

Reliable, simple, and e-bike specific hub. To withstand the higher torque of e-drive systems, the 350 hybrid is equipped with steel rotors and a specific 24T ratchet out of hardened steel. Oversized bearings ensure smooth running under extreme conditions.

DT's 350 MTB rear hub offers top-end performance for all your riding needs. DT Swiss' Ratchet freewheel system provides precise engagement, high load capacity, and reliability. The Ratchet System driver is extremely durable and can be easily serviced—without tools—in minutes thanks to it's press fit assembly. The press fit assembly also allows the hub to work with a wide array of axle configurations; by simply swapping out the tool-free end caps (sold separately), you'll be able to enjoy the legendary DT Swiss quality on almost any bike. • Accepts 6-bolt rotors

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.
