In BMX Racing, every detail matters. From the first pedal stroke to the finish line, power, precision, and reliability make the difference between winning and losing. The Pride Newton SX crankset was engineered with a single goal in mind: maximize performance without compromise. Developed with advanced engineering and designed to meet the demands of elite racers, this crankset is the perfect blend of strength, efficiency, and innovation. Built for those who push their limits, the Newton SX delivers the responsiveness and durability needed to dominate the track.

The Newton SX crankset is the result of Finite Element Analysis (FEA), a cutting-edge engineering process that simulates real-world forces and stress distribution to refine every design detail. This ensures unmatched performance in BMX Racing, where every watt of power counts.

✔ Minimized unnecessary weight while maintaining extreme stiffness
✔ Reduced lateral flex for a more efficient and responsive pedaling experience
✔ Impact resistance in the toughest BMX conditions

A crankset that maximizes power output, reduces flex, and delivers explosive performance from the start gate to the finish line. The Newton SX is forged from high-performance 7000-series aluminum alloy, ensuring strength and rigidity far beyond that of conventional cranksets.

✔ Increased stiffness for better power transfer—less flex means more energy turned into forward motion
✔ Enhanced durability and impact resistance—engineered to withstand high-intensity racing and hard landings
✔ Optimized structural stability—our waffle-structured design ensures consistent wall thickness, superior strength, and precision in manufacturing

Unlike hollow-forged cranks, which can hide internal weaknesses, the waffle-structure forging process provides better control over wall thickness and structural integrity, making the Newton SX more reliable and stable over time.

The Newton SX also features an integrated chainring bolt system, eliminating the need for separate bolts—simplifying the setup while increasing rigidity.

✔ Fast and easy chainring swaps thanks to the integrated bolt system—no more hassle picking bolt lengths
✔ Increased stiffness—fewer weak points mean a more rigid drivetrain, better power transfer, and improved longevity
✔ Optimized Q-Factor of 168 mm, the ideal position for BMX Racing
✔ Perfect alignment for maximum power and stability
✔ Optimized pedaling position for smoother, stronger acceleration

With a Q-Factor of 168 mm, it offers the ideal stance for BMX racers, balancing stability and efficiency at every pedal stroke. Weighing in at just 738g (175 mm version), the Newton SX is among the lightest BMX cranksets on the market.
