These 9 speed chains work with ALL 9 speed mountain and road bicycles on the market. The outer plating's proprietary design gives the Connex 9 speed chain the highest shifting performance available and the high performance 9sX is made of high tensile stainless steel, which increases the life of the 9 speed chain by 20 percent. All of our nine speed chains are compatible with the Connex Link which allows the chain to easily be removed without dismantling the bicycle.
