Made to the same tried and tested RHM shape as their top end Alanera bar, the Zero 2 Handlebar ensures comfort, and speed of movement, whether you're on the drops or on the flats. The RHM shape is a design that has weathered the ages, and will do so for a long time to come. It features a very shallow drop, which is especially designed for riders with a high out of saddle position. A compact reach makes it perfect for modern brake/gear controls. The patented multi-position Continuous Incremental Radius design overcomes the limitations of the anatomical shapes, which has just one position. These bars feature a drilled entry hole for installation of Di2 bar-end junction box.
