This tool kit has been assembled over 15 years and 60000 miles of touring. http://share.ovi.com/media/currentre...resident.10301 The crank puller has been filed down to fit the 15 mm wrench which also fits the pedals and both hubs. The bottom tool has been filed down to perfectly fit the adjustable wrench. The screw driver is actually a drill chuck there is a T20 bit and a multisize drill bit. The 8mm 9mm 10mm sockets came from a multitool and fit a 6mm hex wrench. A 12mm socket was filed using the Smith and Wesson diamond file shown to fit on the 10mm Allen wrench it fits the pedals. There is also a piece of a chain saw file. There is also a 8mm 6mm 5mm 4mm 3mm and 1/8 inch Allen wrenches. The 1/8 inch is for working on grip shifters these always galvanic corrode the 1/8 can be hammered into the 3mm socket to remove it. I suggest you get the multitool with a chain tool and the sockets but also buy the loose Allen Wrenches. You can carry a smaller wire cutters buy high quality here these are easy to break and you will be lucky if you don't end up with the broken handle through your hand. I also carry a water key that I recently lost.
