About this item
- Smooth Operation: Equipped with sealed bearings, this derailleur pulley reduces friction and ensures quiet, efficient gear shifting. The 13T teeth provide smooth chain engagement
- Lightweight Aluminum Alloy: CNC-machined from high-grade aluminum alloy, the pulley is both light and strong. The anodized black finish resists wear and corrosion
- Wide Compatibility: Fits most mountain and road bike rear derailleurs with 4mm, 5mm, or 6mm spindle shafts. Check your deraille’s compatibility before purchase
- Easy Replacement: Simple installation – just remove the old pulley and attach this one using the existing mounting hardware (screws not included)
- Enhanced Performance: Upgrading to a sealed bearing pulley improves drivetrain efficiency and prolongs component life. Suitable for various cycling conditions

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

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.
