  • Show all items from HayesHayes Bicycle Group is a manufacturer of high-performance bicycle components, including disc brakes. The company was founded in 1991 and is headquartered in Grand Rapids, Michigan. Over the years, Hayes has established a reputation for producing durable and reliable disc brake systems for a variety of cycling applications, from cross-country mountain biking to downhill racing.

    Hayes offers a wide range of disc brake models to suit different riding styles and preferences, including hydraulic and mechanical systems. Their hydraulic brakes use a closed system of mineral oil to transmit braking force from the lever to the caliper, resulting in a smooth, consistent feel and increased modulation. Their mechanical disc brakes, on the other hand, use a cable actuation system, making them more economical and easier to maintain.

    One of the key features of Hayes disc brakes is their use of four-piston calipers, which provide more stopping power than traditional two-piston designs. This makes them ideal for use on steep and technical terrain, where stopping power is essential. Additionally, Hayes uses high-quality materials in the construction of their disc brakes, such as heat-treated aluminum and stainless steel, to ensure durability and longevity.

    Hayes also places a strong emphasis on product development and innovation, and they regularly release new and improved disc brake models. For example, their latest hydraulic disc brake system, the Code RSC, features a more compact design, improved modulation, and increased power, making it a popular choice among mountain bikers and enduro riders.

    In conclusion, Hayes Bicycle Group is a respected and trusted name in the bicycle industry, known for producing high-quality disc brake systems for a variety of riding applications. With a commitment to innovation, quality, and durability, Hayes continues to set the standard for disc brake technology in the cycling world.
