Tools included are 2,2.5,3,4,5,6,8mm hex keys; a Phillips screwdriver; and T25 Torx. The X-Tool weighs a scant 115g. This is ideal for bicyclists who need a small basic tool, just enough to be prepared. The larger overall size (3.8" long) of the Topeak
X-Tool provides for better leverage than some competing smaller mini bike tools. Made with hardened steel tools, all of them fold into a composite body. Compare to Park
multi-tools - equal or better quality, at a great price level. All you'd need is a 10mm hex for bottom bracket bolts, and you could make almost any repair with this small portable tool.
