Park Tool CNW-2 Chainring Nut Wrench

Park Tool CNW-2 Chainring Nut Wrench

This handy tool fits securely into the slots on the reverse side of a chainring bolt so it doesnt spin while you loosen the bolt. Designed specifically for the job, the revised CNW-2 (replaces CNW-1) makes removing chainring bolts much easier.

  • One end has a two outer tips nominally 2.7mm wide each, and the other end has tips of 3.8mm each
  • The blade thickness is nominally 1.35mm

    Does the Job!
    This tool makes working on chainrings much easier than using a flathead screwdriver. It works fairly well and locks in pretty well. It can be a little hard to hold while also using the allen wrench, but it is easier than anything else.

    PROS: Efficient, cheap

    CONS: Slightly Unwieldy

    A must have tool
    This is the second chainring bolt tool that I've bought. The first was a one-sided Park. This one is double sided. It's small and easy to misplace. I attached a 2" ring to it so It'll stand out it the toolbox. End your frustration and buy the right tool for the job.

    PROS: Versatile, Good Grip, Rugged

    Can be useful
    I bought this but it can be a take it or leave it item. I added it to my on the road kit. I never needed it to remove chainring bolts. Though I have used it for the sake of trying it out. May come in handy for siezed bolts. Good quality and tough. Park quality of course.
