The Cutter Doc Y-Key includes 4, 5, and 6mm hex keys to help you fix your derailleur, tighten your headset, or snug down your pedal and keep from walking home. Cutter’s three-prong design gives you way more leverage then a standard L-style wrench, so that half-rust, super-stuck bolt doesn’t stand a chance.

Nice Travel Tool

    This was a great tool to have on my recent trip to Spain and France. It came in handy for tightening up the parts that the substandard French mechanics failed to. It was also nice for removing pedals from one rental bike to the next. It's relatively small and packs easily.

    Awesome convenient tool

      This tool is one of my go too tools for quick adjustments on the bike. This gives you the best of both ends of the traditional L-shaped allen/hex wrench. It has extension, to reach those bolts tucked behind other components, and has torque power to tighten without having to pull the tool out due to having limited rotation room.

      With some bolts, it performs worse, such as disc brake calipers, due to the spokes getting in the way, but for a vast majority of other bolts, I find it does a faster job.

      Cutter Doc Y-Key is a must have...

        The Cutter Doc Y-Key is a great tool at a ridiculous price and has been my most used bike tool for the last couple years. The design provides great grip and leverage, which is especially handy for loosening stubborn bolts and even pedals. It's a nice size as it fits easily into any pack and with three common Hex sizes, has saved the day more than once. The Cutter Doc Y-Key is a clear cut winner - 5 Stars.

            I am interested in this tool. I am wondering...

            I am interested in this tool. I am wondering if one of these allen wrenches is the appropriate size for seat adjustments. I dont have set of wrenches that i can compare with. Do you know if 4/5/6 is commonly used for a seat post size? If it matters the bike is a Bianchi Castro Valley. Thanks.
