The X9SL features KMC proprietary X Bridge shaping on the outer links. This produces a very stiff link assembly for more accurate shifts and less stretch for better longevity and life cycle. Both inner and outer links are completely nickel plated and have weight saving cut-outs. The pins are hollow for additional weight savings and help bring the total chain weight down to a scant 255 grams. The bushing-less roller design is super smooth and very quiet during operation. The MissingLink connecting link is reusable for the life of the chain and makes installation and removal an easy task. Simply put this is the one of the best 10 speed chains you can purchase and is proven to work flawlessly on all 10 speed road and mountain drivetrains.

The 9 speed specific X9SL chain fits all Shimano, Campagnolo and SRAM drivetrains. Each chain includes KMC's magical MissingLink master link, which provides you with tool-less installation and removal of the chain. Perfect for routine maintenance and cleaning duties.
