    Arguably the most popular tool in cycling.

    When making adjustments to your bike, the three most common hex sizes are 4, 5, and 6mm. Park Tool, being the savvy purveyor of bicycle repair equipment that it is, developed what's quite possibly the most iconic shop tool ever -- the 3-Way Hex Wrench.

    Known internally at Park Tool as the AWS-1, and to mechanics worldwide as a 'Y-wrench,' this three-way has 4, 5, and 6mm hex wrenches. Each are bonded to a sturdy plastic center handle in order to ensure a firm grip. And by having three sizes instantly available, you'll spend less time fumbling around, and more time fixing things.

    Literally Get's the Job Done!

    • Familiarity: I've put it through the wringer

    It's a "Y" wrench by Park Tool, there isn't to much to say.
    It is well made, fits tight into the bolt heads and has a little longer reach than most. Would buy again if I lost this one.

    You need this, you just don't know it...

    • Familiarity: I've used it several times

    It is so nice to grab one tool and be able to adjust almost everything on my bike. This is replacing an "all in one" tool that I have had for years. If you have used the all in one solution, you know it is good in a pinch on the trail, but is more difficult to use than dedicated tools like this. I keep this with me when riding with large groups or on bike trips when mechanical work is a possibility. This is one of those purchases that you wonder how you lived without it.

    bought one for the truck...

    • Familiarity: I've used it several times

    These are just too handy to not have around. Bought this one to keep in my truck for trailhead tightening and adjustments. Easy in the hand and easy to manipulate. On occasion the shape won't let it get into tight spaces, but 90% of the time this works great.

    MUST HAVE!!!

    • Familiarity: I've put it through the wringer

    Between this and the Park Tool Hex & Torx 3-Way Wrench they cover 90% of the adjustments and maintenance for my bike. For sure my go to tools.

    superb tool from Park/Bondhus

    • Familiarity: I've put it through the wringer

    With this tool and the 4,5,6mm version you have in just two tools the hex wrenches needed to perform 90+% of the tightening of hex bolts on a typical bike.

    Ball driver wrench

    • Familiarity: I've put it through the wringer

    Most frequently used tool you can have on the workbench. Definitely go with the ball driver version as it allows you to tighten / loosen things are funny angles.


    • Familiarity: I've put it through the wringer

    Bought this tool for small adjustments or emergencies out on the trail. It has worked great so far, and I expect to keep using it for years to come. I would highly recommend this product!


    • Familiarity: I've put it through the wringer

    I got this and tossed it into my bucket of cleaning and maintenance supplies. It does what it is suppose to and has taken a beating but still going strong. Very happy and would buy again!

    My Daily Driver...

    • Familiarity: I've put it through the wringer

    Great tool for daily bike maintenance. Features a great #4 hex, an even better #5, and the best #6 hex on the market. For all your metric adjustments this fits the bill.

    Should Have Bought It Years Ago

    • Familiarity: I've used it several times

    I wish I could get back all the lost time searching for hex keys in the garage. This has the 3 most used hex sizes, feels great in the hands and allows better leverage to easily torque those bolts!

    Not the 3 Way you are thinking

    • Familiarity: I've put it through the wringer

    As a home mechanic, I got by just fine using a multitool for pretty much all my repairs as I had basically everything I needed all in one tool. While it worked well, fiddling between different sizes got old and I realized there was a better way. This is that better way. Not only do you have the most commonly used sizes all on one simple tool, you can apply torque much better for them. This tool is definitely something that is a staple to have in your toolbox for wrenching.
