The Retül Vantage tool sits comfortably at the forefront of bicycle fitting technology. But in simpler terms, it's at the heart of everything we do. And while this is all well and good, you're here to learn how it works, and more importantly, how it can benefit your ride, so let's get into the details.
The Vantage Tool is comprised of four infrared cameras that detect a series of 16 LEDs that are attached to you via a wireless harness. As you ride free of any wires, it's collecting a massive host of information, ranging from Stroke Intelligence to body alignment. We'll first cover the former. You can think of it, roughly, as a motion capture system, but ending there would be selling it short. Stroke Intelligence is cycling-specific and designed to analyze your pedaling on a stroke-by-stroke basis, without necessitating any lengthy set-up period for the fit technician.
As it gathers rich intelligence, it measures the joint angles of your lower extremities throughout the pedal stroke. This means that it will be recording, and averaging, the entirety of your body alignment, covering the angles of your ankles, knees, and hips at numerous points of each revolution. It also gathers three-dimensional information about the movement patterns of the knee in the forward, aft, side-to-side, and downward motions. Altogether, Vantage analyzes 20 data points in order to determine where your pedal stroke begins and how your body is pedaling.
The collected data is then transmitted over our proprietary RF signal, and we've even taken care to ensure that each component has two processors (one for signal and another for analyzing data) in order to avoid interference and system drag, all without any reliance on post-processing. This allows both you and your fit technician to see the most accurate data possible in real time, which in turn allows your fitter to see the results of position changes both quickly and accurately.
While the Vantage hardware is nothing short of exceptional, its software is equally impressive. It operates off of 10 years of historical data, built up from thousands of bike fittings, which is also known as the Zin Tool. And with this data, it creates "norms" for position that are based off of a comprehensive historical archive of rider positions and corresponding power production and efficiencies. Coupled with the hardware, the system ensures that you'll be receiving a robust set of data like no other. And more importantly, this guarantees that you'll find the perfect position on your bike in an incomparably quick period of time.
