No sorting through plates to find the right weight, the colors make it simple to quickly add the right weight you need. Built with durable solid rubber and steel inserts, they are strong for Olympic lifts and repeated drops. The low bounce with a Shore durometer of 88 (+/-5) means your barbell wonxe2x80x99t travel far when you let it fall. The minimal bounce rubber design is safe for home use, reducing noise and damage to your floors like other plates. These weight plates are also ideal for building overall strength with exercises like squats, deadlifts, chest presses and more. Plates come in 25 lb, 35 lb., 45 lb., and 55 lb. with a 450 mm (+/-2mm) diameter and a weight tolerance of +/- 15 grams. They fit on 2-inch sleeves and are intended for multipurpose use so you can build a better, stronger body without breaking your bank. Durometer measurements indicate the density of the rubber and how much a plate bounces when dropped, with 100 being the hard with no bounce, and 65 being softer with a lot of bounce.Material: Rubber; zinc steel inserts Specs: Durometer measurement:88°±5° Collar opening:50.4mm±0.2mm Weight tolerance:±15grams 25LB:diameter:450mm±2mm thickness:30mm±2mm 35LB:diameter:450mm±2mm thickness:41mm±2mm 45LB:diameter:450mm±2mm thickness:53mm±2mm 55LB:diameter:450mm±2mm thickness:60mm±2mm
