The Regina 137zra/1000 525 ZRA Dual Z-ring 124 links chain is a high-performance bicycle component that is specifically designed for off-road and extreme cycling conditions. This chain is an upgrade from traditional chains, featuring a number of advanced technologies that ensure robustness, longevity, and exceptional efficiency.
The 137zra/1000 model is part of Regina's Z-Ring chain series. The Z-Ring design is a significant improvement over standard chains, with its wide-pinned design and two z-ring links on each side. These z-ring links are ingeniously engineered to provide better chain retention and reduced chain slap, thereby reducing wear and chain derailment. This is especially important for mountain biking or cyclocross where the chain frequently experiences high forces.
Measuring 1000mm in length, this Regina 124 links chain is suitable for use in various bicycle applications, particularly those with a 124 link pitch such as 9-speed and 10-speed cassette systems. It boasts a roller pitch of 11.3mm and an inner width of 6.1mm, providing excellent compatibility with different frame designs and cassette sizes.
The outer plates of the 137zra/1000 chain are crafted from chrome molybdenum steel, a material renowned for its high tensile strength and resistance to corrosion. The inner plates are made of nickel-plated chromium molybdenum steel, which further enhances the chain's durability and resistance to wear. The use of these materials ensures that the chain can withstand the intense stresses and harsh conditions encountered in off-road cycling, making it an ideal choice for demanding riders.
Another noteworthy feature of the 137zra/1000 525 ZRA Dual Z-ring 124 links chain is its innovative low-friction bushings and anti-wear coating. The bushings help minimize the amount of chain slack, ensuring better power transfer between the chainrings and the cassette, ultimately translating to improved performance and increased pedaling efficiency. The anti-wear coating, applied to all rollers and bushings, shields them from damage and contaminants, extending the chain's lifespan and reducing maintenance requirements.
The Regina 137zra/1000 525 ZRA Dual Z-ring 124 links chain also deserves mention for its compatibility with various shifting systems, including I.S.G.X.E. (outer plate reinforced with an additional pin), Shimano HG, and Campagnolo C.I.S. Not only does this compatibility extend the chain's versatility but it also ensures seamless integration with various drivetrain components, offering a more convenient and hassle-free riding experience.
In summary, the Regina 137zra/1000 525 ZRA Dual Z-ring 124 links chain is an exceptional product designed for those who value performance, durability, and reliability in their cycling components. With its advanced Z-Ring technology, high-strength materials, low-friction bushings, anti-wear coating, and versatile compatibility, this chain is an excellent investment for off-road cyclists and competitive riders seeking top-tier performance and longevity.
