Motion Pro Master Link Press Tool

This tool is larger and more stout in person than you will think it is from the pictures which was a relief considering its all aluminum. Thats a full-size 520 chain link in the pics for reference. I originally bought this tool to loosen up a couple tight links. (I made a mistake because I was distracted and wound up with a couple tight links). If you are familiar with current bicycle or 70s motorcycle chain tools you will know what I mean about loosening the tight links. I dont know why NO motorcycle chain breakers have that feature these days but they dont. This is the ONLY one I could find that could do that job which is basically pushing on the pin while supporting the chain from the center to take some compression off the o-rings. As a bonus it is PERFECT for putting on master link side plates without accidentally moving the pins but even if you accidentally do you can fix it with this tool. To me this is a necessary tool for people who do chain maintenance and replacement. It is the perfect compliment to a typical chain breaker.
