- Reviewed in the United States on January 24, 2025Color: BlackVerified PurchaseRubber O ring prevents rattle and as far as a ride along chain breaker goes it's top notch.
- Reviewed in the United States on April 1, 2024Color: BlackVerified PurchaseTool is sturdy and well built. My problem is the rubber stoppers and end caps - the end caps are slightly to large for my grips and the rubber stoppers don't work well; they pop out easily and i am worried will lose it on the trail. I will instead keep this in my hip pack along with the granite stash tire puncture tool. Was really hoping i could keep these in my bars and out of my pack, but they are good tools nonetheless.
- Reviewed in the United States on March 9, 2023Color: BlackVerified PurchaseWe’ll will see if I ever use it. It’s crafted nicely. I thought it was neat.
- Reviewed in the United States on August 6, 2022Color: BlackVerified PurchaseRequires an Allen wrench to use. Where do you store the Allen wrench?? Might as well just bring a chain breaker in your pocket instead of an allen wrench. Bad design, the point of these stash tools is that they are indendently capable without carrying other tools!!
- Reviewed in the United States on December 31, 2024Color: BlackVerified PurchaseThis is well designed but a fraction of a millimeter too small to fit a thicker bmx chain!
- Reviewed in the United States on June 23, 2023Color: BlackVerified PurchaseHard to remove and m5 x 0.8 x 16mm screw is too short. Needed a 20mm screw. Not sure if I like it yet
- Reviewed in the United States on January 18, 2021Color: BlackVerified PurchaseAwesome and super light. Fits inside my Bontrager carbon mtb bars. It will take a chain apart. I tested it 3 times just to make sure. To store, make sure you tighten all screws and handle so it doesn't rattle. If you want to get away from wearing a pack, get this.
