Everything you need to recable both derailleurs on a mountain bike in one pack. Designed around Shimano XT M8000 MTB gears, this set pairs OPTISLICK coated stainless steel inner wires with SP41 outer casing, so it's ideal for fitting new gears or giving a tired drivetrain a full overhaul.
The OPTISLICK coating leaves a smooth surface on the inner wire for low friction, while the directionally wound SP41 casing is axially stiff so shifts go through accurately and quickly. The outer is lined with a polymer sheath and pre-lubricated along its length with low-friction silicone grease for a light, consistent lever feel.
