System Alloy 3 Piece 175mm Crank

System Alloy 3-Piece 175mm Crank

Product Overview

The System alloy 3-piece crank is a lightweight performance pedaling platform engineered for competitive BMX riding. The 175mm length with integrated 44T sprocket and forged alloy construction provide extended leverage and responsive power transfer suitable for racing and speed-focused applications.

Key Features

• 175mm forged alloy construction – Lightweight yet durable aluminum alloy material reduces rotational mass while maintaining strength under high-stress sprinting and acceleration; forged construction enhances durability compared to cast alternatives
• Extended crank length – 175mm sizing provides increased mechanical advantage for acceleration and top-end speed; suitable for taller riders and performance-focused racing applications
• Integrated 44T sprocket – Larger chainring optimizes gear ratio for speed-focused riding and racing; increases top speed potential compared to standard 25-40T options
• 4-side taper spindle engagement – Four-sided taper design provides positive, secure engagement with bottom bracket spindle; ensures reliable connection without play or slippage under racing stress
• 3-piece modular design – Separate spindle and crank arms enable independent component replacement if wear occurs; provides maintenance flexibility and extended crank lifespan
