AEST pulley wheel is equipped with a high quality hybrid ceramic cartridge bearing. The advantages of using a ceramic bearing in the rear derailleur's pulleys are the most dramatic of any other bicycle bearing system. This is due to the high speed at which the pulleys spin. Each pulley is machined from light and strong 7075 aluminum and anodized, with laser cut logos. : BrandAEST : ModelYPU09A-07 : Features High Speed High rigidity Long use-life Low heat Low heat dilating rate Corrosion resistance Non-magnetic : ColorRed,Black : MaterialAL7075 CNC processing, Ceramic bearing : FunctionsRear Derailleur Pulley, Inner diameter: 5mm : Best UseCycling,Mountain biking,Road cycling : Packing List1 x Rear derailleur pulley Dimensions: 1.77 in x 1.65 in x 0.08 in (4.5 cm x 4.2 cm x 0.2 cm) Weight: 0.35 oz (10 g)
