I have an older one of these I use on my mountain bike. Has everything I need in a pinch. Bought another one for the road bike that I use on long tours. Nice to have a solid set of tools and a chain break just in case. My old one started to come loose over time but just tightened up the hex bolts on the side and good as new.
You can get a good grip on the tool. which makes it easy and comfortable to use. This also makes it difficult to use it tight spaces. To wide to allow me to make adjustments to my 29er disc brake piston through the spokes. great all around tool, will have years of use.
This tool really comes in handy when you're on the road. It really is a great tool to have when you go on long rides. Saved my bacon on more than one occasion. It has all the necessary tools you need to make quick repairs. I especially like the chain tool.
This is the third one of these I've purchased-I have one in the seat bag of each of my bikes. I have used these for a number of on the road adjustments and have even used it to repair a chain. It's sturdy and is easy to use and covers almost every adjustment you might need to make when riding.
I have one of these tools in every bike bag. They have never let me down. I have one that keeps falling apart because it lost a bolt that held all the key together but it still function properly. Highly recommended tool.
