The Campagnolo EKAR 13-speed groupset, designed specifically for gravel riding, offers a significant new feature - a quicklink-style chain link option. While this feature is not new to the market, Campagnolo's engineers in Vicenza, Italy have always believed that a properly driven and peened chain pin is the safest and most reliable way to connect a chain. Therefore, the inclusion of the C-Link for the EKAR 13-speed chain marks a major change for the brand.
The 13-speed C-Link is crafted from the same high-tensile-strength C67 NiCrMo2 steel and Nickel surface treatment as the outer links of the EKAR chain. To use it, you simply need an approved chain tool for C13 use to cut the full length chain to your desired length and attach the reusable C-Link like any other quicklink-style system. You do not require the new 13-speed Campagnolo chaintool, only one approved for driving a C13 pin out. It is recommended to reuse the link only once after initial installation, and always use a new C-Link (not a worn one) when installing a new EKAR 13 chain.
