Jagwire Elite Link housing is the ultimate combination of durability and attention-grabbing looks. Available in six eye-catching colors, they're designed to improve any bike's performance and appearance. 2x Elite Link Shift Kits are spec'd for use on road or mountain bikes that use both a front and rear derailleur. The housing uses a series of aluminum links to provide a compressionless system for precise shifting performance. But unlike typical compressionless housing, its flexibility allows for tight bends without kinking. It'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 you'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 - Ultra-slick polished inner cables minimize system friction - Durable aluminum housing won't kink or rust and is 20% lighter than typical shift housing - Includes enough housing and end caps for a bike with both a front and rear derailleur, with split (non-continuous) cable housing - Bikes with continuous housing and/or extra-large frames may need additional links and/or liners; service parts are available separately
