These clever reducer sleeves fit inside the TRAMPA bearings & reduce the axle size they fit too from either 12mm Bearings to fit onto 9.525mm Axles or from 12mm to 10mm Axles, most skate trucks have 9.525mm axles. Due to the accurate fitting of the TRAMPA reducer sleeve into the bearing, when the stainless steel half nut holding the hub onto the axle is tightened up too the bearing reducer sleeve, the sleeve works in perfect harmony with the bearing casing, holding it firmly in a precise position on the truck, ensuring a good spin rate from the bearing and giving maximum performance for the rider.
