Would anyone care to offer up some advise as to which cone wrench sizes I should keep on hand? I normally find that I use just the 13mm and 15mm for most of my hub repair work on the bikes I own. I keep two of each and one needs replaced. Thought I would stop by the LBS on the way home and pick up a replacement. However, I have a decent place to work (tools, stands,etc) at my place and I offer it up for anyone to use if they drop by. Any other sizes that come to mind? Do you use them for anything else (i.e..I think it's the 13's that I use on brakes) I'd be interested in what specialty tools you find are major helpful to have on hand.
