Brake lever feel depends on more than just the caliper and pads. The cable and housing connecting lever to brake determine how much of your hand effort actually reaches the calipers versus getting lost to friction along the way. The Shimano BC-9000 Polymer Coated Road Brake Cableset addresses friction with a polymer coating on the inner cables that reduces sliding resistance enough to noticeably lighten lever pull. That lighter feel isn't just comfort—it's feedback you can use to modulate braking more precisely.

Shimano introduced this cable system alongside the Dura-Ace 9000 series and officially approves it for use with Dura-Ace BR-9000/9010, Ultegra BR-6800/6810, and cyclocross BR-CX70 brake calipers. The compatibility restriction exists because the polymer coating creates a slicker surface that requires stronger cable fixing bolt clamping force. Older calipers may not generate enough clamping pressure to prevent the cable from slipping under heavy braking loads. If you're running approved calipers, the system works as designed. If you're using older brakes, some riders sand off the coating where the cable clamps, though that's outside Shimano's recommendations.

The set includes everything for both front and rear brakes: two inner cables at 1000mm and 2000mm lengths, two sections of BC-9000 SLR-EV housing at 800mm and 1800mm, plus the appropriate end caps and cable tips. The housing lengths work for most standard road frame routing, though bikes with unusual cable runs may need additional housing purchased separately. Cut the cables and housing to length during installation, leaving enough slack for handlebar movement.... Read More
