Durable Rubber Outer Hose: The shifting cable' s outer hose is crafted from rubber, which retains its vibrant red color and stays flexible even in cold or warm weather. It resists cracking and wear, protecting the inner cable while ensuring smooth cable movement for precise shifting. Premium Steel Inner Cable: The inner cable is made of premium steel wires, delivering exceptional strength to handle frequent shifting without stretching or breaking. Its anti-abrasion surface reduces friction against the hose, preventing fraying and extending the cable' s lifespan. Built-In PVC Lubrication Tube: PVC tube acts as a built-in lubricant, eliminating the need for frequent manual oiling. It keeps the steel wire sliding smoothly inside the hose, reduces wear, and ensures consistent shifting performance—saving you time on maintenance. Compatibility with Shifters & Derailleurs: Designed to work seamlessly with all standard bike shifters and derailleurs. The cable’s lightweight yet sturdy build optimizes your bike’s shifting response—whether you' re adjusting gears on a road bike or navigating rough terrain on an MTB. 3M Length: At 3 meters long, the cable provides more than enough length to replace worn or damaged shifting cables on both mountain bikes and road bikes. You can easily trim it to fit your bike' s specific size, making it a versatile replacement part for any bike setup.
