While modern drivetrains have made respectable efforts to prevent dropped chains, it can-and will-still happen. And if it happens on a new carbon frame, you're going to have a bad time. For added insurance against gouges and scratches, install the K-Edge PRO Braze-On Chain Catcher. Not only is the K-Edge a frame safeguard, it also ensures you don't miss a big ring to inner ring shift when you need it the most, right before a harrowing climb. Its lightweight aluminum construction simply attaches to frames with braze-on front derailleurs mounts with the included hardware. Made from CNC-machined 6061-T6 aluminum in Boise, ID., it weighs 10g to your steed and is available in six colors. The 3-bolt is compatible with older style SRAM front derailleurs, whereas the 2-bolt works with the majority of Shimano, Campagnolo (EPS not compatible), and newer SRAM front derailleurs.
