Profile Design 1Twenty Road Handlebar. The Profile Design 1Twenty bar represents a quantum leap forward in the fit and performance of road handlebars. The 1Twenty is one of three handlebars in Profile Design's DRiVe series, which conforms to rider morphology rather than forcing riders to adapt to the bar. The series features progressively sized bars designed around a cyclist's most powerful hand positions. The 1Twenty handlebar, situated in the middle of the DRiVe series with a medium reach and drop, provides ergonomics that suit the body positions of most riders, or riders who seek a performance oriented hoods position with an aggressive position in the drops.
