I have a 65' Firestone Warrior Vagabond with a really small sprocket. I am new to this. I also have a problem with the slipping when I pedal. Does this mean the bearings are bad? If so...how can I change the cranks, sprocket, bottom bracket or bearings, without one of those special crank pullers? I have just the basic tools, ie. wrench, channel locks.. Any help would be so great. Love this forum and you all are building some amazing rides. I am new and learning. Was a motorcycle builder but, went with a safer and cooler hobby.
