The Mission BMX 48 spline crank spindle delivers the clean, functional approach the brand is known for. It doesn’t overcomplicate things, it simply provides a solid foundation for your drivetrain that stays consistent over time.
The 19 mm diameter combined with the 48-spline interface ensures a strong connection between the crank arms and the spindle, distributing load evenly across the system. This is especially important in street and skatepark riding, where the drivetrain is constantly exposed to impacts and lateral forces. The cold-forged chromoly construction offers high durability and strong resistance to deformation.
With a 140 mm length, it fits most standard 48-spline setups, making it an ideal replacement or upgrade if you’re looking for a reliable, no-nonsense solution.
