Shimano’s Ultegra HG700 11-speed chain is a great solution for road or mountain riding. Shimano builds its chains based on the number of gears and the “level” of chain. This means the HG700 is an Ultegra/XT level 11-speed chain. Zinc-alloy plated outer links, used in conjunction with a SIL-TEC coating treatment on the chain, help place the HG700 at the pinnacle of shift performance, smoothness, longevity and durability. Stainless steel materials ensure this chain won’t give out any time prior to the chain stretching past its useful lifecycle, even when you ride in poor weather or the chain is under-lubricated.</p>. Weight: 260 grams. 11-speed compatible only. Narrower to reduce chain weight (Same dimensions as a Dura Ace 9000 chain). Non-directional, symmetrical design makes installation easy. Sil-Tec, using PTFE coating, increases chain life while decreasing noise and friction
