About this item
- 【REVOLUTIONARY NARROW-WIDE TOOTHING】Alternating tooth profiles (high and low) precisely mesh with each chain link width. Prevents chain jumping during shifting or impacts – for smooth power transmission in racing and mountain biking!
- 【STABILITY TECHNOLOGY FOR CERAMIC BEARINGS】Integrated bearing retention system prevents axial play. Protects the silicon nitride ceramic bearings (Si3N4) from impact loads – 3x longer service life than standard bearings!
- 【CNC PRECISION MADE FROM AIRCRAFT ALUMINUM】5-axis CNC milling guarantees a ±0.01mm tolerance. Smooth tooth flanks reduce friction by 22% – noticeably quieter gear shifts & higher efficiency!
- 【CERAMIC BEARINGS FOR EXTREME APPLICATIONS】Waterproof Si3N4 balls (90 HRC hardness) resist mud/salt corrosion. Weight-optimized (10T = 31g) – accelerates starts & reduces inertia!
- 【UNIVERSAL 6MM STROKE + REDUCTION KITS】Easy installation on 99% of all derailleurs thanks to the 6mm inner bore + 4mm/5mm reduction sleeves. For gradient or speed optimization!

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.
