Both the AR and RR feature Coefficient aero-ergonomics that make it easier to ride faster on the noon ride or an all-day ride. With a deeper drop and increased rigidity, the RR promotes a more aggressive, aerodynamic riding position. The patented Coefficient SWOPE (sloping, sweeping bar tops) carries over from the AR to relax your upper body and improve respiratory and neuromuscular function.

The RR Bar is Shimano Di2 compatible. It not only accepts the bar end junction, it includes exit holes for remote shifter buttons in four locations (2 each side) on the underside of the tops. It's also compatible with SRAM Blips.

When comparing handlebar weights keep in mind that the average off-the-front computer mount weighs in at 30 to 40 grams. The Coefficient RR is molded using Toray unidirectional carbon fiber and tested to the highest ISO international standards for professional road and mountain bike racing.
