About this item
- 【CNC Aluminum Alloy with Hollow Design】 Precision CNC-machined from high-strength aluminum alloy with an integrated hollowed-out structure. Delivers see strength-to-weight performance, reduced rotational mass, and a smooth, refined finish.
- 【Sealed Steel Bearings for Smooth Rotation】 Equipped with polished, sealed steel bearings to reduce friction, improve drivetrain efficiency, and provide long-lasting, low-maintenance performance under demanding riding conditions.
- 【Wide Compatibility Across Drivetrains】 Compatible with 8/9/10/11-speed rear derailleurs and supports 4mm / 5mm / 6mm mounting bolt diameters. Fits common road, MTB, and gravel derailleur systems.
- 【Guide & Tension Pulley Ready】 Bolt-fixed structure allows use as both guide (upper) pulley and tension (lower) pulley, ensuring proper chain guidance, stable tension control, and consistent shifting performance.
- 【Correct Size Selection for Safe Use】 Standard 11T pulley size matches most stock derailleur configurations. Important: choose the same size or smaller than your original pulley—13T pulleys are typically only suitable for long-cage derailleurs.

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.
