I think the new shock caps are excellent, an improvement over the alloy ones. The alloy ones would wear and get a bit of play in them, the plastic ones are a tighter fit, and shouldn't wear as much. If they do, they're a cheaper replacement. They seem just as strong, and judging by the effort to put them on, and the number of crashes I had at the weekend, they won't be popping off. Once fitted to the ball stud, the hole in the shock cap can be used to take shocks off for rebuilding, to limit the number of times you pop them on and off. Also, with them having the optional bleeder holes, they are multi functional, sealed or vented depending on if you drill them or not, so more options covered in the kit
