Insight MX4

Crankset Insight MX4 2-piece BMX racing with aluminium splined axle.

Brand new for young competition riders of BMX, this ultra-light 2-piece crankset features an arm with a 4-bolt attachment and a 24 mm aluminium splined axle that fits into the crank arm by pressure. The non-drivetrain side has a double-bolt pinch design to keep the crank arms tight and work smoothly, all the way to the podium.

Designed for young riders who need a robust crank setup and want to switch to a 2-piece crankset with a 24 mm axle and 4-bolt chainring attachment, this crankset offers a shorter crank arm length.
