I have had a pair of those Olympic "Reverse-a-bars" (the heavy duty more expensive ones) for a few years. I put them on to protect against minor stuff and as a step for my wife. They are OK for trail riding, working in the woods, etc. and my wife loves the step (I even installed them pointing UP for max clearance). They seem to be strong enough for moderate contact with trees, boulders, cars, etc. but they are not for serious rock crawling where you might come down hard on them. Stuff sometimes gets caught on the ends (like branches and brush) . I did have to slightly move a brakeline support to install them but no big deal. The bars fit very well to the frame. The Massachusetts overkill road salt program (where they pave all roads with salt for six months per year) has caused the bars to rust in places, mostly around the frame brackets. I did not want to drill the (then) brand new body so I opted for these, for now. Someday I'll probably get (or make) some sliders, just in case. Best of luck - John
