I read a post on the iBOB list about the Jethro Tule from Surly. I’m just not down with it.
For $25 you get a bike specific 15mm wrench. Or for $9 at Harbor Freight you can get an entire set of stubby metric and english wrenches. You can keep the 15mm in your bike bag and throw the rest away at that price! Ok I threw them in my toolbox. They are $16, but regularly go on sale for $9.
