KMC X101 112 Link Track Chain

The KMC X101 Track Chain is engineered for the track cyclist who demands absolute reliability and power transfer. Built with a focus on structural integrity, this chain offers 30 percent more strength than standard alternatives, ensuring it can handle the explosive torque of a standing start or a high-speed sprint. The super rigid construction is designed for maximum efficiency, minimizing energy loss so that every ounce of effort reaches the rear sprocket. At a lightweight 375 grams, it provides the robust feel required for heavy track use without adding unnecessary bulk to your drivetrain.

Advanced Durability and SL-X Technology

Central to the performance of the X101 is the patented SL-X technology, which utilizes a sealed locking design to keep lubrication trapped exactly where it is needed most. By retaining grease within the bearings, the chain experiences significantly less internal friction and a much longer lifespan. This is further enhanced by a unique stretch-proof treatment that reduces attrition between the inner plates and the pins. These innovations work together to provide an extremely durable component that maintains its precision and smoothness even under the most grueling training schedules.

Refined Aesthetics and Compatibility

Beyond its mechanical prowess, the X101 features a striking brass-plated finish that offers both corrosion resistance and a premium look for your build. Designed with a standard 1/2" x 1/8" pitch and 112 links, it is perfectly suited for track bikes and high-performance single-speed setups. The 10.0mm pin length ensures a secure and stable fit across your chainring and cog. This chain represents a top-performance choice for riders who refuse to compromise on strength, longevity, or the signature gold-tone aesthetic of a professional-grade drivetrain.
