Not only are there 23 pro quality, hardened tools but they're housed in a protective plastic case that mounts to any frame tube via Topeak's QuickClick system. Of course there's a wide array of wrenches Allen, Torx, open, box, socket hex, spoke but there's also a Phillips screwdriver plus a disc brake spacer.
