GOLDIX 104BCD MTB Bike Crank 170mm Aluminum Alloy Chainring

GOLDIX 104BCD MTB Crank Engineering and Specification Details

The 104 bolt circle diameter design represents the most common standard for modern mountain bikes, ensuring compatibility with the widest selection of aftermarket chainrings and upgrade options currently available. A 170mm crank length strikes the balance between leverage and ground clearance that most riders require on technical terrain, preventing pedal strikes during aggressive cornering or rock garden negotiation. Aluminum alloy construction maintains structural rigidity while keeping rotational mass minimal, a combination that translates directly into responsive acceleration and efficient climbing power. Chainring options span 32T through 38T, allowing you to select the exact gear ratio matching your terrain and fitness profile without expensive full crankset replacement. This bottom bracket system integrates with standard taper interfaces, making installation straightforward with basic tools and enabling future upgrades as your riding demands evolve.
