Bought this tool as I was tired of always reaching for different the 4, 5 and 6mm allen keys when working on my bikes. It's a time saver, but due to the design, does not work well in areas with less clearance such as some seatpost saddle clamps.
What a great tool. It's 90% of what I need every single time I work on the bike. And it's all there in one hand. If I ever lose it, I'll get another the next day.
These are the industry standard
Solid handy little tool. Just the right size allen keys. The build is solid and give you good leverage. Won't fit all of your bicycle repair needs but will do the job 80% of the time in 1 tool.
I needed a new 5mm allen, so I thought I would give this a try since there are so many 4,5,6 sizes when working on bicycles. It is good quality, but I find I can't spin it as the other sides get in the way. I don't use it as much as I thought I would.
Portable, works for most adjustment points on my bike, allows you to provide enough torque to loosen stubborn bolts...all in all a good investment.
Having been both a bike mechanic (home and professional) as well as an avid cyclist for many years, I can honestly say this is one of the most important tools for anyone who rides a bike to have in their home toolbox. If you're making adjustments, its' very nice to have the three most common hex key sizes right there handy without having to fish around in a toolbox. If you're toolbox is as messy as mine, that can be a bit of a frightening undertaking!
