Pride Newton SX Youth Crankset

Up until recently, options in a two-piece crankset have been limited in sizes under 170mm, with just a couple brands offering them. Options for cranks of this quality have been even more scarce, so those younger racers, or riders looking for a crankset strong enough to take on today’s SX tracks have been making compromises. But not any more.

Pride has developed and released the Newton SX crank to compete with the world’s best BMX race cranks, on the world’s biggest stages! They are 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.

In BMX racing, as in any performance sport that involves man and machine, there is a fine balance between lightness and strength. Parts light enough (especially rotating mass components like cranks) to give the rider an edge over their competitors, but strong enough to be both durable and able to withstand the big hits wrong things go wrong.

This is the advantage that Finite Element Analysis (FEA) brings to the table.

✔ Minimising unnecessary weight while maintaining extreme stiffness

✔ Reduction of lateral flex for a more efficient and responsive pedalling experience

✔ Impact resistance in the toughest BMX conditions (those big cases)

✔ Optimised structural stability—our waffle-structured design ensures consistent wall thickness, superior strength, and precision in manufacturing

The Newton SX crank is forged from high-performance 7000-series aluminium alloy, ensuring strength and rigidity far beyond that of conventional cranksets.

Additionally, 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. We’re big fans of this system as the bring:

✔ Fast and easy chainring swaps thanks to the integrated bolt system—no more hassle picking bolt lengths

Other highlights

✔ Optimised 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.
