Appreciation post: the $9 chain tool that saved my Saturday group ride in Tucson
My chain snapped 4 miles from the meetup spot at Sabino Canyon and after two broken quick links I finally dug out the cheap chain breaker I almost left at home, got the pin pushed through on the third try, and rolled back in just as everyone was clipping in, so what small tool have you almost tossed that ended up bailing you out?
