KMC

The KMC X12 Ti-N gold-and-black is designed for mountain bikes. The manufacturer specifies it for 12-speed drivetrains. This is a top-of-the-line model.

The first thing that catches the eye is its unique appearance. The gold-and-black links are very attractive. The gold color is due to a titanium nitride coating. However, it's worth noting that the manufacturer wasn't solely concerned with aesthetic appeal. This surface finish ensures reduced friction and improved anti-corrosion properties. For this reason, titanium nitride is often used in high-end tools.

The chain's excellent properties are paired with its low weight. The manufacturer's stated weight of 268 grams is enough to make others envious. Other features of the chain include:
The use of Hi-Pformance and Extremely Durable technologies makes the product incredibly durable and strong
Symmetry - KMC X12 Ti-N is non-directional, meaning it can be mounted without considering the direction
Works perfectly with SRAM and Shimano drivetrains

The chain comes complete with a clip.

Size: 1/2"x11/128"
Connecting pins: 5.20 mm
Missing-Link chain connection clip included

The X10SL is a high-end 10-speed chain. The technology used ensures the lowest chain weight, making it the lightest chain in its category. The X-Bridge design increases shifting speed and precision. A premium nickel plating prevents corrosion. All KMC chains are highly compatible with any drivetrain and can be used non-directional, making installation much easier. The combination of extremely high strength, excellent performance, and a nickel plating makes the X10SL chain the ultimate addition to your bike.

Improve your ride with KMC GO WAX

Experience the next level of chain performance with our new, advanced dry wax formula. Designed to significantly reduce friction, improve shifting, and ensure optimal efficiency, KMC GO WAX extends drivetrain life by forming a durable microfilm on the chain that repels water and resists dirt adhesion.

For cleaner, faster and longer-lasting performance.

DURABILITY: Once applied, the wax dries to form a protective barrier that is more durable than oil-based products.

CLEANER RUNNING: Our waxed chains attract less dirt, minimizing common causes of wear and ensuring smoother operation.

SIMPLE MAINTENANCE: With minimal dirt buildup, your drivetrain requires less maintenance. Refreshing the wax is simple—just use a dry brush or cloth. No degreasing is required, just a simple touch-up with KMC GO WAX.

ENVIRONMENTALLY FRIENDLY: KMC GO WAX is biodegradable and contains no PFAS or harsh solvents, making it a responsible choice for both your bike and the environment.

Good for your ride, great for the planet

We're pioneering change with our premium chain line and are paving the way for a future where our entire chain range will be free of mineral oil-based lubricants. By producing around 5 million chains per year in the X-series alone, we'll soon save around 20,000 kilograms of mineral oil-based lubricants per year.

This change is just the beginning. Consider the enormous amounts of oil traditionally used to maintain chains and its impact on our environment. Our wax-based solution not only improves drivetrain efficiency but also significantly reduces the environmental footprint of our products by preventing harmful chemicals from entering our ecosystems.
