Jagwire Elite Link Shift Kits are the ultimate combination of durability and attention-grabbing looks. 1x and 2x versions are offered to maximize compatibility with nearly all frames and shifting systems. Available in six eye-catching colors, they're designed to improve any bikeâ€™s shifting performance and appearance. The housing uses a series of aluminum links to provide a compressionless system for precise shifting. But unlike other compressionless housing, its fLEXibility allows for tight bends without kinking. Itâ€™s also lighter than traditional linear strand shift housing while being more durable. Combine these benefits with Elite, ultra-slick polished cables and Slick-Lube liners, and youâ€™ve got the best of performance and style. Precise, compressionless shifting performance combined with extreme fLEXibility. Each kit comes with links pre-installed on housing segments making setup quick and simple. 20% lighter than typical shift housing. Durable, ultra-slick polished inner cables minimize system friction. 2x kits are designed for use with both front and rear derailleurs, while 1x kits are for rear derailleurs or internally geared hubs only.
