Dimensions AeroGain BTA System mount plate
Measure the distance between the bolts securing the left armrest, and the bolts securing the right armrest.
If the distance between them is between 54 and 148 mm, choose the narrow width mount plate. If the distance is between 148 and 198 mm, choose the wide plate.

Your aerotest will be led by Kristoffer Visti Graae — a professional triathlete and aerodynamicist with a PhD in applied physics. Kristoffer has spent years developing and refining aerodynamic testing protocols, combining deep scientific knowledge with real-world racing experience.
He has tested and optimised the setups of some of the world’s top triathletes, including Kate Waugh, Kristian Høgenhaug, Josh Amberger, and much of the Danish elite triathlon scene. Whether you're chasing marginal gains or looking for a major performance breakthrough, you're in expert hands.
Kristoffer’s approach is practical, precise, and tailored to each athlete. Every session is built around your specific equipment, position, and goals — using controlled velodrome conditions to measure even small changes in drag and rolling resistance. The result: clear, data-backed decisions that help you go faster without sacrificing power.
