6mm actually5mm (IIRC) tip
Anex makes a tool similar to the OEM one, just a touch smaller, that works pretty good. And it's made in Japan and not china like most everything else these days.Any other cool alternatives? I figured some of you would be cyclists and the bike world is full of super compact light tools for allen bolts. I'll noodle around a bit, too.

There's also a straight handle version. Available for under $20 on Amazon
