Introducing the SU-31172 EVS Link Belt Silent Chain from Sunlite, a high-performance alternative to traditional bicycle chains. This 72-link chain is designed specifically for use with Shimano and SRAM 11-speed drivetrains, ensuring seamless compatibility with a wide range of bicycle models.
The SU-31172 chain is renowned for its silent operation, thanks to its unique roller design that significantly reduces the noise commonly associated with cycling. These rollers are precision machined from high-quality steel, allowing for smoother and quieter operation, even under heavy loads. Additionally, the rollers are coated with a durable PTFE material that minimizes friction and wear.
This chain features a 1/2 x 11/128 pitch, making it an ideal replacement for the Shimano HG-73, HG-75, and HG-77 chains. The 72 links provide sufficient length to accommodate various frame sizes and configurations, ensuring a perfect fit for most bicycles.
Each link in the SU-31172 chain is designed to be both strong and flexible, enabling optimal power transfer from the pedals to the rear wheel. The rollers are also designed to be self-lubricating, reducing the need for frequent chain maintenance. However, it is recommended to periodically clean and lubricate the chain to ensure optimal performance and longevity.
The SU-31172 chain is also known for its durability, which is crucial for any cycling enthusiast. The pins and rollers are made from high-strength steel, while the bushings are constructed from hardened steel, ensuring the chain can handle the rigors of intense riding.
In summary, the SU-31172 EVS Link Belt Silent Chain from Sunlite is an excellent choice for those seeking a high-performance, silent, and durable chain for their 11-speed Shimano or SRAM drivetrain. Its unique design features, including the silent rollers and self-lubricating properties, make it a must-have accessory for any serious cyclist looking to enhance their riding experience.
