Cult Crew BMX Crankset – 175mm 19mm Spindle Black

Product Overview

The Cult Crew 3-piece crankset is a chromoly crank system designed for BMX street and park riding. It features a hollow 19mm spindle with 48 splines, single-sided sprocket boss, and full RHD/LHD compatibility for either pedal setup.

Key Features

• 3-piece construction – Arms and spindle separate for easier installation, removal, and replacement of individual components
• Wrap-around gusset design – Reinforces the crank arm–to–spindle junction; increases rigidity and distributes stress more effectively during hard tricks and landings
• Heat-treated swaged chromoly arms – Tubing is tapered at stress points to reduce weight without sacrificing strength; heat treatment increases hardness and durability
• 19mm hollow chromoly spindle – Lightweight yet stiff; hollow core reduces rotational mass for responsive pedal feel
• 48-spline interface – Industry-standard spline count for compatibility with most BMX sprockets and hubs; allows easy swaps without tools
• Single flush-mount hollow spindle bolt – Minimalist design reduces frame contact and snagging; hollow design keeps weight low
• 1-piece spindle/sprocket boss – Integrated design eliminates separate fasteners; sprocket mounts directly to spindle for direct power transfer
• RHD/LHD compatible – Works with right-hand or left-hand drive setups; spindle accepts either configuration without modification
• Lifetime warranty – Manufacturer backs product against defects in materials and workmanship
