Flat Bars= GGGGGGGGAAAAAAAAAAAAYYYYYYYYYYYYYYY!!!!!!!!!!!!!!!!!!!!!!!!!!!! Someone is just trying to start some gay trend. If flat bars are awesome for DH they would have been popular a long time ago. Flat bars are for riders with that mid 90s Classic Hardtail (2inch travel fork) cross country bike that they just can't part with.
surely once you get bars theis wide you'd have to be riding at sub human speeds to feel unerved but lets face it how close does any one get to as fast as Sam Hill
