Ideally Suited For:

  • Aggressive Gravel Riding & Racing
  • ITU Draft Legal Triathlon Racing

The RR's patent pending integrated computer bridge is not just a perch for your favourite data capturing gizmo, it offers hand placement options to powerfully and comfortably lift you over a steep climb AND/OR stretch-out and narrow-up to bridge a gap or breakaway from the pack. Designed within UCI and ITU rules, the RR will change your cycling experience for the better.

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. Our 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.
