I find gerber the superior multi tool and am never without mine ( exc. Court and in the shower) . I have used it on every major component of bike more then once. The same tool itself has saved the day at more then one rally roadside breakdown
to bad all the patents for that type of tool are taken an motorized bicycle version would be great!
The other day I had stoped to grab a beer and had to dig thru the tools in my jacket to get to my wallett the bartender mubled "so thats wat it takes to ride on of those bikes"
