What Our Gearhead(R) Experts Are Saying:"I keep this in my repair kit for swapping chains at home and for emergency fixes out on the trail. It breaks links cleanly without chewing up the plates, and the spare link set has saved more than one ride."A snapped chain miles from the trailhead can turn a good ride into a long walk, which is exactly why the Chain Breaker Tool earns a permanent spot in any repair kit. It breaks worn links, seats new ones, and gets a drivetrain running again with a few confident turns of the pin pusher arm, whether that repair happens in the driveway or on the side of a singletrack climb.
