The Beringer Junior crankset is designed for BMX race competition.
This crankset is the fruit of French machining expertise and technical knowledge of high-strength alloys.
The hollow construction of its CNC-machined 6082 forged aluminum cranks and 24 mm hollow CrMo steel axle provides excellent rigidity. This guarantees optimum power transfer.
The J2's new crankset axle is a 24 mm steel axle with 40 splines, including 1 coding. Its design allows for easy assembly with the adjustment screw, and a solid hold thanks to axial clamping, thus eliminating any play.
The key features of this crankset are ultra-light weight, rigidity and product durability.
