At Tate Labs we have in depth product knowledge & hands on experience with some of the worldÂ’s fastest most technologically advanced aerodynamic components. These insights helped us in creating the Bar Fly TT. The Bar Fly TT was designed specifically for Triathletes & Time Trialists & incorporates the same patent pending 1/8th turn mechanism used on the Bar Fly 1.1. Because 1/8th turn allows the display to be mounted in 90Â’ increments Bar Fly TT is compatible with the Garmin Forerunner watch & Garmin Edge series cycling computers. Bar Fly TT accepts a variety of mounting options for both computers along either side of the aero extensions & allows plenty of room for your aero bar mounted hydration & nutrition accessories.
