K-Edge Chain Catcher Installation
Even the most well tuned and perfectly aligned derailleurs can drop a chain every now and then. Rough roads, poor shifting technique and just freak occurrences can lead to chains dropping off the inside chainring. This circumstance is annoying in the least, delaying your ride and forcing you to mount the chain back on the drivetrain. At worst, the chain may damage the bottom bracket when it comes off, or become jammed into the drivetrain (ask Andy Schleck about jammed chain woes.) Preventing dropped chains is as simple as installing a chain catcher (sometimes called a chain watcher) on the front derailleur braze on clamp. This simple little part will help to prevent chain drops in even the nastiest road conditions; in fact, they are so effective that the vast majority of ProTeam racers use them in the spring classics. If it's good enough for the pro peloton, it's certainly good enough for me.
