I have a used PureFix bike where the chain tensioners are just a pair of machine screws that run through the frame. Over time, the screws bent, the frame started to rust them in place, and they were a pain to remove. They also stripped the threads on the rear axle. These tensioners are an excellent alternative and are much easier to work with.
