    Before I bought the wrench, I read comments about it. Someone wrote that it had sharp edges. It’s true for mine also. Other then that everything was in order. It helped me do the work I needed it for.

    I might sell or might keep it. I have not decided yet. If I’ll keep it, I will smoothen out edges and wrap leather handle around it. (For better grip)

    That’s all I have to say, hope info helps to someone else. 🤚🏻

    I was sold as soon as I changed my first cog with this tool. This even took off a stripped lockring I thought was on the wheel permanently. The tool’s good quality guarantees a tight, accurate fit on your lockring, and the added length both adds ideal leverage and keeps knuckles farther from the spokes. I wrapped the end I don’t use in tape, which provides a better grip and cushion. It’s Park Tool; you always get the best quality.

    HCW-17 also works(loosen/tighten) for stock locking ring on the non-drive side bottom bracket. My bike is stock non-sealed Bottom Bracket, general build for most manufacture. The locking ring is 43mm with 6 notches. I used this tool's end with 43-44mm. I could have used cressant wrench, but it would damage the clean look of the locking ring. I decided to get the correct tool HCW-17. Its strong/durable enough to last a lifetime. I did not have problem with this tool slipping when turning or getting scratch knockles or gouging the paint job in bottom bracket shell. Just be straingt when you turn. Unless you are a gorrilla, then you shouldn't be fixing bicycles!

    Seems pricy but if you work on your own bikes it will pay for itself in two uses between the time it takes to travel to the shop, pay the shop to work on your rear wheel, and travel home. Worked super well also.

    Does it what is says on the tin. I only need to change my fixed gear a few times a year and usually spend 10 minutes at the job with a hammer and screwdriver, resulting in much swearing and bloody knuckles each time. I gave up on the latest job after 30 minutes hacking away at it, and purchased this tool instead. When it arrived in the post, it was larger than I expected, and gave me all the leverage and grip I needed to fix the job in 10 seconds. Without swearing and bloody knuckles. :-) If you look after fixed gear bikes, a tool like this is a welcome addition in the toolbox.
