Needed to upgrade to actual hex wrenches after only using a multi-tool for ages. Great set. Way, way better having the full-size versions for better leverage. Happy to have the holder to keep things compact and organized as well.
Hex wrenches, the ubiquitous tool for bicycle fasteners. The Park Tool HXS-1.2 Hex Wrench Set is the industry standard. The set has all the sized you will need for bicycle maintenance and the wrenches are made with precision by Bondhus in the USA. Wrenches are long for leverage and the end has a ball driver which lets you turn a bolt at an angle. That is handy in tight spaces. The holder keeps your wrenches organized so you can find what you need on the fly.
Any cyclists who takes care of his or her own bikes needs a good set of hex wrenches. This is the best, and most affordable, set I was able to find. And to top if off, the best brand when it comes to bike tools is Park! I particularly appreciate the length of the longer sides as it allows me to adjust my mechanical disk brakes with the wheel on the bike.
One practical advantage is that the blue holder folds and that therefore this set takes up a lot less space in my tool box than a previous set with the same number of wrenches. I haven't had many chances yet to use them, but noticed that the smaller sizes are a bit flexy. I don't think that there will be any issues with real use, though.
