Features1Aluminum Alloy Material: The bike hub is made of aluminum alloy with a surface anodized finish and a dazzling anodized coloring process. It provides better protection for the metal surface, enhances wear proof performance, and extends the lifespan of the hub. It is also eco friendly and safe for health. 2CNC Machining: The hub is processed through CNC machining, providing erosion resistance, impact resistance, and strength while reducing weight. It maintains its shape without deformation or warping and is resistant to rust. 3High Density Tooth Engagement: The high density tooth engagement ensures a tight and secure fit. With high toughness and minimal effort, the hub can engage the teeth at a small angle during pedaling, making it easier to generate power. 4Highly Precise Cutting Technology: The hub features a standard 6 claw disc brake and a 44mm hole distance, allowing for stable installation of the hub. It provides exceptional performance for mountain bike disc brake systems. 5Complete Accessories: Each shipment includes 2pcs 32 hole hubs, front 2 bearings and rear 5 bearings, 2pcs quick release levers, and 1pcs washers, satisfying your needs and providing all the necessary components for installation.SpecificationItem Type: Bike HubMaterial: Aluminum alloyWeight: Approx. 739g/26.1ozColor: ColorfulBearing: Front 2 bearing, rear 5 bearingHoles Number: 32HSpeed: Freehub body supports 6 7 8 9 10 11 speedPackage List2 xBike Hub2 x Quick Release Lever1 xWasher
