Your cart is empty.The CNW-2 makes chainring bolt set installation and removal easy. It securely holds the slotted nut to prevent spinning when tightening or loosening the bolt. Double-ended to fit most slotted-type nuts, including the Campagnolo® chainring nuts.

Slotted chainring bolts can be a pain, the screwdriver-like tool previously used requires pushing inward and rotating the bolt, all while keeping the tool straight to stay engaged with the slots. You might also need a stick to clamp between your teeth to keep from cursing, and paper towels and duct tape to make a bandage if the tool slips and the chainring bites you. This Park tool makes the process much safer and less frustrating for certain.

Not much to say, it is a good Park tool but I had to use it very carefully to get the chainring bolts off I was struggling with. They were really tight.

In the process of converting my Catrike back to manual with very little bike maintenance experience I found myself needing this special tool and not having one. It was a pain. I tried a bunch of alternative method to get the chainring tightened but nothing worked until I was able to get my hands on this. Seems pretty solid and definitely good enough for a casual bike rider and mechanic

With inflation affecting my life, I always try to cut some corners with cheaper brands but always return to Park Tools. This tool wasn't that much more expensive but still tried to shave some coins. It turned out that I made a mistake. The tool worked like expected and it also caused less damage to my chainring bolts, which I can reuse. Thanks.

Works well! But it feels flimsy, the metal is very lightweight.

Works really well, solid construction, used on a derailleur bolt, allowed to tighten properly - would recommend.

Outils de bonne qualité, résiste au vis serrées très fort. La clé ne s'émousse pas, et se tord pas malgré sa petite taille. Je vous conseille de démonter le pedalier et de se mettre bien à plat, ça évite de ripper et taper les mains dans la couronne.
