Jagwire's Red Elite Sealed Shift Cable Kit is a top - notch choice for both road and mountain bikes. These kits come with ultra - slick polished uncoated inner cables and Slick - Lube liners that significantly cut down friction. The continuous Slick - Lube liner and grub seals at the liner ends protect the cables from dirt, water, and other contaminants, without sacrificing high - level performance. Small parts are included for easy installation on dropbar or flatbar bikes. There's enough housing for most full - length runs. The XEX housing is 30% lighter than traditional shift housing, and the cable ends are compatible with SRAM and Shimano. Note that the 5.0mm shift housing and 1.9mm inner liner may not fit all frames and components.

Using this cable kit is easy. First, gather all the parts included in the kit. If you're installing on a dropbar or flatbar bike, use the provided small parts for the installation. Make sure to route the housing along the bike frame properly. When it comes to the inner cable, thread it through the Slick - Lube liner carefully. As for maintenance, regularly check the grub seals at the liner ends to ensure they are keeping contaminants out. If you notice any dirt or water getting in, clean the cables and the liner. Also, keep an eye on the friction level. If you feel that the shifting is becoming less smooth, it might be time to replace the inner cable. Remember, the 5.0mm shift housing and 1.9mm inner liner may not be compatible with all frames and components, so double - check before installation.
