Jarruvaijeri Shimano DURA-ACE BC-9000 Polymer Coated

Shimano Polymer coated Road brake inner cable made of stainless steel with excellent anti-rust protection (SUS). The secret is polymer coating that when viewed under a microscope looks like a series of tubes wrapped around the cable. This means less surface area rubbing the internal housing liner and it holds grease longer. Main benefits are significantly less shifting effort and the feeling of a quicker shift action also improved braking power with remarkably less brake lever effort.
