Using all of our racing experience, we 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® Ultralite™ 4X chainrings are designed to ride faster, jump further and last longer.
