Keep the chain were it belongs.
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 a 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 and is available in six colors -- Black, Blue, Gunmetal, Gold, Red, and White. It comes with 2 mounting bolts -- 20mm for Shimano or Campagnolo (except Campy EPS), and a 25mm for SRAM.
