Just be careful. Some frame sliders are quite effective while others are just for show. I have seen two basic problems, so far. The first are mounting screws that are way to small to withstand any sort side impact, which is highly likely in a slide down the road situation without just snapping off the screw. The other, and even more unfortunate situation is when the slider is secured onto something completely unsuitable for task. I have actually seen situations where the slider greatly added to the severity of the damage. The fairing generally gets ruined anyway, but when the slider destroys the frame by directly transferring the impact into something that otherwise would have been unaffected and was not able to withstand the impact. So, give a little attention to the screw size and exactly where the thing is attached. There’s always somebody out there anxious the sell you something, but it’s up to you to consider the design merits and not just the desired ‘look’, but it’s function as well.
