Well that's kinda scary. I don't have any on my FS, but I've actually had to replace the one's on my HT because I ate them up so much. They're aluminum and I had almost gotten through the metal in a couple places. Um, not from crashing or anything, tho...I only fall down when I plan to. And if you believe that....

Friend of mine just got a GF Tassajara. I'll see if it came with barends. I haven't thought to look at the LBS. Mine work fine and are nowhere near needing to be replaced so I don't really think about it. I probably couldn't find another pair of the same ones now anyway.
