The AeroGain BTA (Between/Behind The Arms) system allows you to mount two bottle between your armpads.
With the change in Ironman and World Triathlon rules eliminating the possibility of having a bottle or water bladder down the front of the race suit, a similar aerodynamic gain can be obtained by raising the bottle so that it sits close to the chest, closing the otherwise empty area there. Depending on the rider, this can further improve aerodynamics and lead to those total compared to having no BTA bottle.
The AeroGain BTA system is designed to integrate seamlessly with your existing pads, and will fit most triathlon bikes. It works by the baseplate being clamped between the mounting bridge, and your pads.
The BTA double bottle mount comes in different angles, and different plate widths.
Comes without bottle cages.
