The Ergo is the core of our new family of fit and comfort  focused armrests. It offers a smoothly curved shape designed to comfortably cup the elbows while providing good support and control. The bolt pattern yields 48 possible configurations just by moving the armrest. The Ergo is compatible with all current aerobars and earlier models that used the F-19, F-22, F-35 or F-40 armrests.

Rotating the pad 180˚ alters the reach offset by 7.5mm - the smallest increments of any aerobar that doesn’t have sliding parts

Swapping the pads from ones side to the other changes the width by 9.5mm per side for a total change in pad width of 18.5mm.
