Tooth disc + bearing + seal + end cap + 2x O-ring + spacers (0.1mm + 0.15mm + 0.2mm) The hubs set standards in terms of durability and weight. If the freehub’s splines wear out after prolonged use, you can find all the parts here to restore it to like-new condition. Of course, the kit is also suitable for changing the freehub standard, for example, when switching from SRAM XD to Shimano Microspline or vice versa.When choosing Highspeed bearings, you get minimal rolling resistance and maximum speed for dry conditions, while Enduro bearings are designed for maximum durability and load capacity under harsh conditions. Important information: The N3W and MS freewheels only fit the new axles. Please check which axle you have; you may need to order an additional axle. The old axles have a step. The diameter is slightly smaller. The new axles have a continuous diameter for freewheel bodies with 3 bearings.
