I have a "new for me" Lemond that came with a KMC 10S Missing link. This is the first removable link I have had on a chain. Do they work? Do you need a special tool like Parks MLP-1 ? http://www.parktool.com/products/det...t=5&item=MLP-1
Is it a single-use link? I have seen conflicting info on if its single use or not. How many times can you take it off before it gets to loose?
