11T Mountain Bike Cassette Replacement Cog (8 to 12-Speed Compatible)

Restore your drivetrain's smooth shifting without replacing the entire cassette. This high-quality 11-Tooth (11T) Replacement Cassette Cog is the perfect solution for mountain bikers experiencing skipping or excessive wear on their highest gear. Designed for universal compatibility with 8, 9, 10, 11, and 12-speed setups.

Crafted from ultra-durable steel, this lightweight sprocket features an optimized tooth profile engineered to reduce friction, minimize drivetrain noise, and increase overall wear life. It is an essential, cost-effective maintenance part for any avid cyclist.

Product Notice: This listing is for a single 11T replacement cog, not a complete cassette. It is designed to fit standard Shimano-style (HG) splined freehub bodies.

UK Stock & Fast Dispatch: Order with confidence for fast, reliable delivery direct from the UK.

Key Features

Optimized Tooth Profile: Advanced tooth design increases chain retention, ensures crisp shifting, and reduces friction and chain noise.
High-Strength Durability: Forged from premium steel for maximum ring durability and resistance against heavy torque and wear.
Cost-Effective Repair: Save money by replacing just the worn-out 11T cog instead of throwing away an otherwise perfectly good cassette.
Easy Installation: Super lightweight and designed for quick dismantling and installation using standard cassette lockring tools.

Important Installation Notes

Chain Compatibility: If you are replacing a heavily worn 11T cog, it is highly recommended that you inspect your bicycle chain for "stretch" and wear as well. A new cog paired with a worn chain may still result in skipping under load.
Proper Torque: When installing the lockring to secure this new cog, ensure it is tightened to the manufacturer's recommended torque setting (typically 40 Nm) using a proper cassette lockring tool.
