- Familiarity: I've used it several times
I consider these an absolute necessity in any "worst case scenario" mountain bike tool kit. A broken chain can turn a super sweet ride into a super long walk and is one of the worst events that can befall a biker.I have broken a chain before and the PowerLock connector made the repair a snap. I also took confidence in the knowledge that I did not have to pop any pins so my chain could be counted as good as new, without any weak spots. Neither my wife or I ever go on a ride without these in our bags.
