This is my choice of multi-tool and I have purchased many of them to equip our entire fleet. It is very well made, has the essential tools and a chain breaker, and is light. I pulled it out recently to repair someone's seat clamp - they were sure glad I had it.
Packs a lot in such a tiny multitool!
Ive only had to use a chain tool once on a ride, but it really saved our butts. I bought this to replace a similar (bulkier) Lezyne multitool from a few years ago, and Im thrilled.
