Excellent product
This is one of the best little bike tool sets money can buy. It has a majority of tools you may need when you need to make quick adjustments. Design and durability is second to none, and all the tools are fairly easy to use. It is small enough to fit into a small backpack, or even into your pocket. Big plus with this kit is inclusion of the tire patching kit, may not be the best, but in the pinch it will do the job just fine. Considering how many tools are included on it, it is not that heavy, although it is a little hefty, but that's only due to everything you get with it and because of the quality steel they are using. Great tool for the money.

Good tool, but not a all in one.
This is a good universal tool however there are parts on my bike that this does not cover. So I do need to carry additional tools with me. For my bike it is not a all-in-one tool. However I do enjoy having this and I give it a good review because it does have a lot of good pieces to it.

Well built and reliable tool
Great multi tool for bikepacking and around town rides. The individual tools are easy to access and very compact to store in a frame bag or handle bar bag.

Excellent Multitool
I’ve had this for well over a year and it has been useful on occasions when you need to make adjustments or quick repairs both at the trailhead or the trail itself. It has a lot of useful tools, and yet the best part is it is very portable with a small thin profile that easily stows in your bag or even jersey pocket. It weighs less than half a pound and yellow side rails help it to stand out in a sea of black so it’s easy to see when you need it. Highly recommended.

Perfect, Compact Tool Kit
This is a really nice, compact tool kit that has just about everything you’ll need for a quick fix while on a ride. I love having a tool kit that is so compact it fits anywhere and has the tools I need to make on-the-fly adjustments to my pedals, seat, bars, etc. if/when I need to. I’ve found this especially useful when trying out new products like shoes and pedals where even the slightest adjustment can change the feel of your ride from painful to comfortable. Overall weight for this particular model isn’t bad for its size. This tool kit would make a perfect gift for anyone that rides regularly. Great product.

Good tool, made nice and solid and it has every bit I have needed so far, the only thing is the chain breaker wasn’t big enough to put my shimano chain pin back in

Great tool but with this many finctions it is of course a little bit heavy. No problem for me but could be an issue for those chasing grams on their ride.

Das Crankbrothers M20 Multitool gehört definitiv in jede Satteltasche oder in den Rucksack. Es ist kompakt, extrem robust und bietet alle wichtigen Werkzeuge, die man unterwegs braucht – von Inbusschlüsseln über Torx bis hin zum Kettennieter. Besonders praktisch ist das integrierte Reifenreparatur-Set mit Plug-Werkzeug und Aufbewahrung für Tubeless-Plugs – perfekt für schnelle Notfälle auf dem Trail. Die Verarbeitung ist wie immer bei Crankbrothers hochwertig und langlebig. Alles wirkt durchdacht und zuverlässig. Für mich ein echter Lebensretter auf längeren Touren und das perfekte Tool für alle, die vorbereitet sein wollen. Kurz gesagt: ein Muss für jeden ernsthaften Biker!
