Rail Chainring loose (another thread)

[ronianash]

I saw a different thread about this and someone made a tool to tighten. In the meantime, mine is loose and wondering how I should tighten with everyday tools. Will I have to take the crank arm off if I wanted to apply some lock tight??

Also, those of you who bought the Parktool wrench to tighten, has it stayed tight??

Mine came loose. Took to LBS they had tool to tighten. They locktited,torked 30 nm. Hasn't loosened since. I also read thread checked and it was loose. Saved me lot of troubles. I assumed they had to remove arm.

To use a proper tool yeah you have to remove the crank arm. You can use a hammer and punch but I’d not recommend it. You’d most likely damage the nut and you’ve no way of knowing the torque it’s tightened to.

Must have tool. Mine kept coming loose. Not after torque,all good
