This is a brand new chain. Never used. Extra inventory that we have on hand to build new bikes. You basically get a new chain without the box. It's the exact same item, just no box. The KMC X-Series has been designed with the specific characteristics of the Shimano, SRAM, and Campagnolo systems in mind and will meet the most demanding requirements. Elaborately designed and manufactured, the X-Bridge technology, thanks to precisely chamfered plates, allows a smooth propulsion and perfect gear changes in all driving situations.
