I had a look at these, they don't appear to be built super strong. Where do they get this extra strength from? I used some Cycra ones on one of my other bikes and they seem to be built a lot stronger than the Barkbusters. I haven't binned it hard enough to test them yet. But I have destroyed a couple of sets of Barkbusters. Plus about 5 sets of handlebars, on my other bikes.
