Built from a lifetime of riding and racing experiences, and inspired by life itself, the latest generation of the Ritchey Comp Streem brings fully internal cable routing to this legendary handlebar. The Streem bar has long combined the performance and advantage of an aero bar with all-day comfort. A generous aero-formed top section provides sleek performance and ergonomic support. While its comfort is bolstered by the stress-relieving compact drop, ever so gentle back sweep and slight drop flare, its increasing radius drops offer multiple hand positions. Now updated with the ability for fully internal cable routing, the new Comp Streem ups its advantages to fortify its position as the perfect choice for road racers and serious enthusiasts who demand performance without sacrificing comfort in the everlasting quest for great ride experiences.
