ProWheel Pioneer 170 Crank and Chainwheel Set – Stealth Black (42T)

Description

High-Torque Performance & Rigid Trail Mechanical Efficiency

Maintaining smooth mechanical power transfer over loose sand, thick mud, and severe incline accents puts high structural pressure on your bike’s primary rotational drive assembly. The ProWheel Pioneer 170 Crank and Chainwheel Set is built to balance physical toughness with clean, responsive pedaling dynamics. Cut from premium forged aluminum alloy with an anodized matte stealth black finish, the 170mm crank arms resist bending under high-impact torque while keeping the bike’s center of mass centered.

Note on Factory Engravings: While the integrated outer protective chain guard features an industrial stamp indicating up to 48-tooth clearance capabilities, this official FM 500 / FM 750 OEM variant is factory-fitted with a dedicated 42-tooth gear cluster. This explicit sizing reduces your front-end circumference, altering the physical chain loop length requirements to maximize lower-gear mechanical leverage for superior all-terrain hill climbing.

Technical Highlights

• Optimized 42T Gear Mapping: Physically counting exactly 42 drive teeth, this layout optimizes your chainline for high-torque hub motor assist ratios, accelerating cleanly from a standing start.

• 170mm Forged Alloy Construction: Ultra-rigid arm architecture eliminates flex under deep standing pedal pressure while providing optimal clearance over trail rocks and roots.

• Integrated Protective Bash Guard: The dual-sided outer guard shields your chain from direct impact damage, limits chain drops on rough downhills, and keeps clothing clean.
