AeroGain BTA Mounts and Spacers offer aerodynamic efficiency, secure bottle placement, and full adjustability — trusted by top triathletes for high-performance setups.

Measuring for AeroGain Baseplate:
- Measure the Horizontal Distance Between Arm Pad Bolts.
- Measure the horizontal distance between the two bolts you currently use to mount your arm pads.
This is where the AeroGain base plate will be installed – it fits between the cockpit and the arm pads, as shown in the diagram and images below.

Choose the Right Base Plate Size:
- Medium Base Plate – for bolt spacing between 54 mm and 148 mm.
- Wide Base Plate – for bolt spacing between 130 mm and 198 mm.
