These may be a couple of grams heavier than KMC X 10SLs but even a die-hard weight weenie like me appreciates their smooth shifting and lower friction (yes these can be made to go under 5W total friction at a 200W input). If you are riding Shimano/Sram and race.....these are the chain for you. Comes with a couple of extra joining pins.
