So, mountain bikers think theyre tough, right? They can handle anything the trail throws at them, but can they even fix a simple broken chain link? I mean, Ive seen road cyclists do it with their eyes closed, but I guess thats not exactly relevant here. Seriously though, whats the best way to fix a broken link on a mountain bike chain? Is it better to use a quick link or a chain breaker? Should I just replace the whole chain or try to salvage whats left? And dont even get me started on rust - how do you guys deal with that? Do you just let it eat away at your chain until it breaks, or is there some secret trick to keeping it at bay? Im genuinely curious, because Ive seen some of you guys out on the trails with chains that look like theyve been through a war. Help a guy out and share your expertise.
