Renthal BMX Alloy Chainring

Using all of their racing experience, Renthal have designed and developed 4X and BMX Ultralite chainrings to offer the ultimate combination of lightness, strength and durability. All Renthal chainrings are individually designed, by tooth size, to give the maximum strength to weight ratio. We use the highest quality aluminium and the hardest wearing surface finishes to keep your Renthal chainring running smoothly, in the toughest conditions, for as long as possible. Renthal BMXAlloy ChainringFeatures Precision CNC machined to extremely tight tolerances to give the ultimate combination of strength and light weight. The 7075 T6 aluminium alloy rear chainwheels are 66% lighter than steel, yet incredibly durable. Their advanced tooth profile, concentricity and accuracy of fit provide maximum power transfer and long-life. Renthals combination of a very high strength base material and an exceptionally hardwearing surface result in significantly increased chainwheel life.
