Stainless steel construction is critical to having a multi-tool that doesn't rust, I keep this in my saddle bag and as much as I try to stay dry I get caught in the occasional downpour and usually don't bother drying everything out after my ride. Tools with just a coating on the bits will rust very quickly as I found out the hard way with about 4 different brands. I got the 7 bit version and it has everything you need for mid-ride adjustments, it is solidly built and again the fact that it hasn't started to corrode makes it a keeper. I use a Speedsleev saddle bag, which is awesome BTW, and even though it is supposed to be waterproof nylon humidity makes its way into it as there is no zipper to fully close it (its only downside IMO).
Have not used and I hope I don't need too. The best safety tools are those you never will need.
Super compact and lightweight tool that I keep in my seat bag. I like that it has a chain breaker on it incase my chain acts funny while out on a long ride. Quality seems to be there.
Well made, with just the right tools for everyday riding. One of the lightest I could find that was quality made.
