4X / BMX

close-window open-window

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 Chainrings : Designed to ride faster, jump further and last longer

Hard Anodised

We use a hard anodising process to hugely increase the longevity of the SR4 chainring. The durable surface finish not only resists wear, but also keeps your SR4 chainring looking fresh.

CNC Machined

Each chainring is fully machined from high grade 7075 T6 aluminium. Computer aided design allows us to machine away all unnecessary material and retain an incredible strength to weight ratio.

Chain Compatibility

The 4X chainring is compatible with all modern 8, 9, 10 and 11 speed chain. The BMX chainring is compatible with 1/8" and 3/32" chain.

Crank Compatibility

Renthal 4X and BMX chainrings have a 23.8mm axle bore. The chainring is supplied with aluminium adaptors for 19mm & 22mm axles, covering all fitment options.
