The VO Crazy Bars are intended for touring on paved and unpaved roads, single and double track, gravel and crushed limestone, and everything in between. The main, swept back section provides excellent control and leverage on rough and tumble surfaces, while the the bullhorn section offers an aero position for smoother roads and headwinds. The junction of the horns and sweeps feels similar to being on the hoods of drop bars and makes for a nice, neutral position. The main bar uses a 22.2mm grip area so MTB grips, levers, and shifters fit. The "horns" are 23.8mm, so road components like bar ends and inverse levers are compatible. The stem clamp area is 31.8mm.
