I tweaked a pair, so it's not impossible to bend them. I bought another pair, because I was still very impressed with them. On my new set I even twisted my Atomic 22 big bar mounts, and the bars are still unbent. I tweaked my first set after I cased one of the doubles here at home on my track, but to some people I suppose they were in still rideable condition. Except they made my left arm pump up, so I replaced them. Best bars I've yet to come across. In McGrath's case, those were prototype bars, and were used on his bike before released to the public.
