TO be perfertly honest with you there not that much stronger than a normal chain, but they do last a little bit longer. They can be a b*****d to fit, Especially the Shadow V2. But get one If you don't like it youll know never to buy one again. I think there great and use one at the moment. But, everyone else said that they weigh a ton, and they dont get loose then snap, they just snap. But as long as you check the tension of it before a propper ride it'll be fine. Jarrod
