These suckers are light--and once you get used to the knife edged blades they're not so bad. Two big issues, though: the hinge rattles incessantly, which is really inexcusable considering a $.008 cent viton o-ring during the mfg process would do the trick. Instead, every 100 or so miles I have to squish a chewed up piece of gel block into the washer to shut it up. They fit the Vision bar, but they'll only fit other bars with an adapter (that makes them heavy). When I went to upgrade my vision base bar to an Easton I had to score new brake levers.

Decent design and semi-light/minimalist structure, but knife edged (eg better for an all out race bike that doesn't see street duty). Installation was a breeze, but these f'ers RATTLE like crazy. Expect to spit, shove or shovel silicon, gu and/or gel blocks into the hinge washers, because they make a lot of noise if left alone (a .003 cent rubber grommet inserted during the mfg process would bump my review up 2 stars).
