Hero Genuine Chain Sprocket Kit for Glamour, Glamour FI – Part No. 20K810S

Buy the Hero Genuine Chain Sprocket Kit (Chain Kit / Chain-Sprocket Set) for Hero Glamour & Glamour FI with part number 20K810S. This OEM kit is built for correct pitch, smooth power transfer, and longer drivetrain life—ideal when your chain is noisy, slipping, or worn out.

The Hero Genuine Chain Sprocket Kit (20K810S) is the OEM drivetrain replacement kit designed for Hero Glamour and Glamour FI / Glamour PGM-FI variants. This is the part riders and mechanics commonly call a “chain kit” or “chain-sprocket set”—replaced when the chain starts elongating, sprocket teeth hook, or the bike develops jerks and vibration under load.

Choosing a genuine Hero kit matters because drivetrain components must match precise OEM specifications for sprocket alignment, tooth profile, and power delivery. Local or duplicate kits often lead to early wear, extra chain noise, uneven pickup, and frequent adjustment. With the original kit, you get predictable performance, smoother riding feel, and better long-term reliability—especially important for daily-commute bikes like the Glamour series.

As per Hero’s own product listing, this is a Hero Genuine part (common name: Chain Sprocket Kit, net quantity 1 unit, country of origin India) and is intended as a direct replacement for the compatible Glamour platforms. 
At underthehood.co.in, we focus on genuine packaging, careful packing, and fast dispatch, so you receive the correct, authentic part without the counterfeit risk.
