DK Social Bicycle Crank

Product Overview

The DK Social Bicycle Crank is a one-piece crankset built from tubular 4130 chromoly with forged pedal and spindle bosses. Designed for durability and direct power transfer, it works across street, park, and trick riding with right-hand or left-hand drive compatibility.

Key Features

• Tubular 4130 Chromoly Arms – Hollow-core construction reduces weight while maintaining strength. Chromoly resists impact and fatigue from tricks and landings without brittleness or cracking.

• One-Piece Forged Pedal and Spindle Bosses – Bosses are forged (not welded) directly into the arm structure, eliminating weak points at connection zones. Forged construction increases durability and reduces stress concentration during high-impact riding.

• 19mm x 48T Spindle – 19mm diameter provides adequate stiffness for direct power transfer without excess weight. 48-tooth configuration delivers balanced gearing for general BMX riding across trick and park styles.

• Flush Mount Hardware Included – Hardware sits flush with crank surface, reducing snag points and debris accumulation. All fasteners included—ready to install.

• RHD/LHD Compatible – Works with right-hand drive (RHD) or left-hand drive (LHD) bottom brackets, offering flexibility across different frame setups and rider preferences.
