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.A Dependable Hub:- The freehub Ratchet System makes the 350 the dependable partner for any ride.Notool 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.Brake Interface:- The advantage of the Center Lock system is that the disc brake attachment is made with one single lock ring, which facilitates assembly. On the other hand, an advantage of the IS-System (6 Bolt) is that in the event of a necessary repair on the trail, no special tool is needed for disassembly. IS 6-Bolt:- IS is short for International Standard and describes a mounting system for brake discs. 6-bolt refers to the fact that the brake disc is in this case mounted on the hub using 6 bolts.Shimano Light (ASL):- Milled aluminum freehub body for Shimano 10 and 11-speed MTB cassettes. Visit the brand website for more details about the compatibility of the freehub bodies.Thru-axle:- Thru-axle refers to a wheel mounting system. RWS technology from DT Swiss allows quick, precise mounting simply by turning an easily adjustable lever. Thru-axle systems guarantee a rigid and secure connection between the wheel and the frame. Thru-axles must be compatible with the frame and fork because the built-in-width, diameter and thread of the axle vary and are defined by the frame and fork manufacturer.Boost:- Boost refers to wider axle dimensions. Frame and fork manufacturers use this to build a stiffer bike overall. A flatter spoke angle on the wheel can be created by increasing the flange distance, which improves the symmetry and increases the stiffness, especially on large wheels.Specifications:- Net Weight: 273 g- Material: Aluminum- Field Of Application: MTB- Cassette Interface: Shimano MTB- Freehub System: Ratchet System 36 SL- Axle System: 12 mm Thru Axle- Built-In Dimension: 142 mm- Number Of Holes: 28- Brake Interface: Disc IS (6-bolt)- Freehub Body: Shimano Light (ASL)Technology:Bearing Technology:- DT Swiss hubs are designed to function optimally once installed in a bicycle. To achieve this, the clamping force created by the wheel mounting system must be taken into account when constructing a hub.
