Stainless steel gives you corrosion resistance, and PTFE coating gives you reduced friction. Combining the two in a single brake cable means you get both benefits without compromise. The Shimano PTFE Road Brake Cable uses their SIL-TEC treatment process to apply a die-extruded PTFE layer to the individual wire strands before they're wound into the finished cable. This construction method bonds the coating at a deeper level than post-formation treatments, so it stays intact through years of use rather than flaking off and clogging your housing.

The friction reduction translates to lighter lever pull and more consistent modulation across the entire stroke. You feel more of what's happening at the brake caliper because less of your input gets lost to drag inside the housing. The difference is most noticeable on longer descents where repeated braking compounds any inefficiency in the system, but even on flat terrain the smoother cable action simply makes the bike more pleasant to ride. The PTFE also creates a barrier against water and grime infiltration, which extends housing life by protecting the liner from the abrasion that contaminated cables cause.

This cable originally carried Dura-Ace branding, though Shimano has since moved to labeling their top-tier cables by coating type rather than groupset name. The performance is the same: wound SUS stainless steel construction with PTFE treatment, compatible with virtually all road brake levers including Shimano dual-control, SRAM DoubleTap, and traditional non-integrated designs. The pear-shaped cable head fits the standard road lever interface.... Read More
