Jagwire Sealed Brake Kits use a continuous liner that seals the system completely, protecting it against dirt, water, and other contamination. Available in three colors for road bike brake systems, this system offers the ultimate combination of protection and low-friction performance. To ensure the best possible performance, we've paired Elite Polished Ultra-Slick inner cables with our Slick-Lube continuously-lubricated liners. This combination delivers precise cable movement and excellent durability. The continuous liner running from the levers to the brake calipers offers outstanding protection from dirt and debris. Elite Polished Ultra-Slick cables are paired with Slick-Lube liners to minimize friction. Since most high-performance mountain bikes use hydraulic or mechanical disc brakes with full housing, Elite Sealed Brake kits are available only for road bikes.
