KIT ZONE
It always surprises us in transition areas when we see deep-rim wheels, integrated tri-bars and truncated aero frames on a superbike… only for a pair of rounds own wind tunnel research and that conducted by XLab and more has shown the benefit of mounting the bottle behind the saddle in the slipstream of the rider. That said, and while it's no fault of this Zefal set, we do seem to drink less with the bottles behind instead of mounted on a tri-bar or down tube.
