As someone else pointed out, it can be damn slippery. My Masi came with the original bars wrapped in yellow Benotto. I went with it has long as I could, but could no longer tolerate the angle of the bars and the correspondingly
funky positioning of the brake levers once I corrected the bars, so I dumped the slippery stuff for yellow Newbaum's with a "cushion" underneath made from a bit of inner tube.
