About this item
- High-Quality Aluminum Alloy: Lightweight & Durable This bike crank arm (compatible with bike crankset, bicycle pedal crank and bike pedal arm) is crafted from premium aluminum alloy, balancing performance and longevity: Lightweight: Reduces overall bike weight without sacrificing strength, enhancing riding efficiency and reducing fatigue on long trips. High strength & deformation resistance: Withstands pressure from pedaling and rough terrain (like mountain biking) without bending or warping. Durable: Resists daily wear and tear, ensuring long-term use compared to low-quality metal or plastic cranks that break easily.
- 170MM Size: Universal & No Interference The 170mm crank arm features a universal design tailored for practicality: Universal fit for mountain bikes: Works with most standard mountain bike models, eliminating compatibility worries. No overlap issue: Crank arm and chainring bolt don’t overlap, preventing friction or damage during pedaling—common with ill-fitted cranks. The 170mm length is a versatile choice, suitable for most rider heights and riding styles (commuting, trail riding).
- Standard Precision Holes: Easy Installation Standard precision-cut holes simplify the installation process: Perfect fit: Holes align seamlessly with bike components, no modifications or extra tools needed. Hassle-free setup: Just align the interface and secure it—saves time and improves efficiency, even for users with basic bike repair skills. Avoids the frustration of mismatched holes (common with non-standard cranks) that delay repairs or cause unstable fits.
- Excellent Paint Finish: Stylish & Fade-Resistant The crank arm stands out with its polished, high-quality paint job: Stylish appearance: The black diamond fine polish adds a sleek, modern look to any bike, upgrading its aesthetic. No fading: Paint resists sun exposure, rain, and scratches, maintaining its glossy finish for years—unlike cheap paint that chips or fades quickly. It combines functionality with visual appeal, ideal for riders who value both performance and bike style.
- Multi-Application: Ideal for Bike Repair & Replacement This 170mm crank arm is highly versatile for bike maintenance: Bike repair essential: Perfect for replacing worn, bent, or broken crank arms (a common issue with frequent riding). Wide compatibility: Works with many bike models beyond mountain bikes (including some hybrid or commuter bikes), making it a handy spare part. It’s a cost-effective solution for keeping your bike in top condition, avoiding the need to replace entire cranksets.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
