A post by In4 in Muppets forum, about a Topeak Peak DX2 pump that he picked up cheap, and my response that it's the best of the mini pumps, reminds me that Topeak also makes something else I consider the best of the best.
The Topeak Toolbar is the best and the lightest of the multitools on the market. My Dutch friend Lou Holtman suggests that it isn't more popular with cyclists because it is too
small and too
light: they think it is a toy. But it is a most competent complete travelling toolkit which weighs 68 grams and hangs on your keyring. You can roll up a glueless Park tube patch and put it inside with the hex bits, and you're ready to go.http://www.sjscycles.co.uk/topeak-topeak-toolbar-compact-multi-function-tool-prod16114/
It's not a toy. I bought mine when the Toolbar first came out, probably a decade ago, and have used it on several bikes, and once left it at an LBS who used it for a couple of months (a marvel that he didn't lose the bits...) until I came in again and said, "Hey, that's my missing Toolbar."
