5 out of 5 stars
Really nice tool kit, and case.
When I picked up the package off the porch I didn’t expect the weight of this little tool kit but when I opened it up I was really impressed with the build quality of this versatile little multi tool. I mention that it is a little weighty, that’s because it’s made of better material and a little larger than some that I have seen, but that’s okay with me because it means I can put more leverage behind this kit if I have to. I also like the case that came with it. Though a little snug, it has a nice brush finish to the tuff plastic body. I did notice however the Anodized finish on the red & black sides that holds the kit together have a very thin layer of coating and is already chipped. But that aside I think this little multi tool kit is going to work out fine. Pros: well made, large enough to get my hand around yet small enough to carry in my bike bag. Nice little case to keep it clean and dry. Cons: cheap anodized finish, heavier than expected. Overall I’m really happy with my purchase of this multi tool kit

    Great quality. May have some tools that you may not need on a day to day basis but it’s good if you are planning to use this as a sole tool for your bike and have a bike mechanic who does the major work. Overall great quality and it’s amazing that it comes with a case.

    If you’re searching for a reliable, all-in-one cycling tool, look no further than the Crankbrothers Multi Tool M19. This compact marvel has quickly become an indispensable part of my riding gear thanks to its flawless balance of portability and robust capability.

    What truly stands out about the M19 is its thoughtful, compact design. It slips easily into your home toolbox, a traveling kit, or your favorite storage pack on your bike—never weighing you down or taking up unnecessary space. Despite its small stature, this tool packs an impressive array of features that inspire confidence on every ride.

    From Allen wrenches in nearly every size you could need, to flathead and Phillips screwdrivers, this tool has you covered for virtually any adjustment. But what really impresses me is the inclusion of a sturdy and effective chain tool. Whether you’re fine-tuning your gears, tightening stubborn bolts, or fixing a popped chain out on the trail, the M19 handles it all without you ever needing to carry a bulky toolbox.

    An additional highlight is the protective flask case that comes with the M19. It keeps the tool clean and secure, no matter where you store it—be it in your workshop, travel bag, or backpack. This thoughtful addition means your multi tool is always ready for action and protected from the elements.

    In summary, the Crankbrothers Multi Tool M19 is a perfect companion for cyclists who value functionality, reliability, and portability. Every tool on it—from the Allen wrenches to the screwdrivers and chain tool—works smoothly and efficiently. Whether you’re out on a long adventure, commuting, or simply keeping your gear tuned up at home, the M19 is the only multi tool you’ll ever need. Highly recommended!

    Solid, well-built. Sprayed some WD-40 on it ;) 2+ year update

    Very pleased with the tool. Tested most of the tools on the bike. No major problems. All hexes fit snug, chain breaker is solid, and tool pivots do not move when using. Will be putting it in saddle bag for all rides.

    I don't care how "heavy" the tool is. A small price to pay for a solid tool. It is possible to break it down into individual components if you want to save some weight.

    Case is aluminum, tools are stainless steel. Some reviews mentioned rust forming early (and I'm not planning on using it unless needed), so I sprayed some WD-40, wrapped it in lightly-oiled paper, and placed it in the case. (the paper also dampens/quiets the tool - can jiggle a little in the case)

    UPDATE: June, 2023

    This tool has seen some usage! Everything perfect except for I broke the chain breaker (don't remember if it was my fault or tools). No rust whatsoever. Hexes are fine with mild corner rounding (very minor though). Had to tight the case a couple times. Love it and will continue to use it forever at this rate!
