Bicycle Crankset Suppliers: Gravel Cranksets and Road Cranksets

LASCO manufactures high-precision, cold-forged cranksets designed to seamlessly integrate with modern frame geometries and major drivetrain ecosystems. Supporting global OEM/ODM projects, we deliver reliable power transfer, precise chainlines, and international testing standard compliance across Road, Gravel, and E-bike platforms.

Gravel Cranksets: Optimized Clearance & Mixed-Terrain Gearing Engineered to resolve the balance between tire clearance and Q-factor on modern adventure platforms.

• Extended Chainline: Pushed outward by 2.5mm – 4.0mm to accommodate high-volume gravel tires without sacrificing biomechanical efficiency.

• 1x & Sub-Compact 2x: Featuring precision narrow-wide profiles for maximum chain retention and optimized gear ratios for technical climbing.

• Forged Durability: High fatigue resistance built for rugged bikepacking and gravel racing.

Road Cranksets: Maximum Efficiency & Precision Shifting Designed for competitive road, endurance, and urban fleets where every watt counts.

• Efficient Biomechanics: Narrow Q-factor (43.5mm – 45mm chainline) for aerodynamic stance and consistent cadence.

• High Stiffness-to-Weight: Cold-forged aluminum arms minimize flex under sprinting loads for direct power transfer.

• Ecosystem Ready: Fully compatible with industry-standard 11 and 12-speed systems, delivering predictable quality for OEM model specifications.
