I like the Spin Doctor multitool I got from Nashbar last year on blowout for something like $15. The chain and spoke tools are really good -- I've used them instead of my shop chain and spoke tools a few times. But there's no way to fold it flat. It mostly goes in my hybrid's larger saddle bag.



Spin Doctor Rescue 16. It's good. Doesn't quite lay flat.

But recently I wanted a minimalist multi-tool that also included a chain tool. It needed to fit inside the dinky Lezyne Road Caddy, along with a tube, levers, patch kit, and maybe a CO2 inflator (the Road Caddy is too small for a complete CO2 kit unless I omit something else).

Amazon read my mind and suggested the Hero Kit multi-tool. It's the first I've seen with a chain tool that lays flat. The reviews seemed honest, mentioning some rusting with the early samples. That's an indication of high carbon steel, which should be tougher. One of my Topeak multi-tools is carbon steel, no problems with rust here in Texas.

So I bought the Hero Kit. It seems good. I've only used a couple of the Allen keys so far, but it seems to be well made. And it fits the Lezyne Road Caddy perfectly.

If I can find a CO2 inflator smaller than my Red Zeppelin I might be able to fit a CO2 cartridge and inflator in the Road Caddy. Pretty good deal for my only carbon bike. On my steel bike I'm less weight conscious and carry a Serfas Speed Bag with plenty of room for junk.
