The Tacx IRONMAN® Smart is the ‘Official Cycle-Mounting Trainer’ of IRONMAN®. Just like the Genius Smart, the Tacx IRONMAN Smart uses the most advanced resistance unit and software which analyses performance and simulates bike courses very accurately. The wireless motor brake converts the properties of the terrain into resistance on the bike, in a highly realistic manner. The bike route is displayed on your screen.
The motor brake is able to apply a maximum power of 1500W to the back wheel. The slopes simulated are realistic up to 20% and down to -5% for descents. The Tacx IRONMAN Smart comes with the Upgrade Smart to connect to a Windows PC and use the Tacx Trainer software 4, Advanced, Skyliner front wheel support, Kona water bottle and the Tacx film of the IRONMAN World Championship bike course in Hawaii (for TTS 4, Advanced).
The Tacx IRONMAN Smart communicates via ANT+ and Bluetooth Smart for convenient training sessions using your smartphone or tablet. Performance data can be viewed on several devices simultaneously, including your smartphone, bike computer and sports watch.
When the Tacx IRONMAN Smart isn’t connected to a smartphone, tablet or computer, it behaves as a fluid trainer. This means the trainer behaves progressively: when your speed increases, the resistance increases as well. So it is possible to use this trainer in a “stand-alone” status.
The motor brake is the most advanced brake, offering the most realistic cycling experience. The brake force is controlled dynamically. This means that the resistance is calculated and adjusted continually to simulate natural road resistance, including during descents.
When calculating the brake resistance, all physical formulas a cyclist encounters on the road are applied, in order to create a situation that is as realistic as possible. Air and rolling resistance, gradient percentage, weight, air pressure, wind speed, temperature, altitude, inertia and brake properties are all taken into account and calculated hundreds of times per second to achieve a realistic feel.
A virtual flywheel dynamically controls the brake force. This means that the resistance is calculated and adjusted continually to simulate natural road resistance. Whereas other trainers use a flywheel to pass the dead centre, the Tacx IRONMAN uses calculations to predict the movements of the bike and simulate the action of a flywheel. The Tacx IRONMAN even has a downhill drive. The wheel keeps turning, so you do not need to pedal, just like in real life. The virtual flywheel can generate a variable inertia effect, allowing it to simulate the bike movements of all cyclists up to a specific bodyweight (125 kg max.) in a highly accurate manner.
The motor brake is equipped with LED lights that move to the rhythm of your cadence. The red lights light up when the power output is high. When the power output is low, the green lights are more visible. The Tacx IRONMAN® trainer has to be plugged into the power grid, apart from this the trainer is wireless.
The Tacx IRONMAN® Smart works without a cadence sensor. The cadence is derived from the variation in force on the pedals and recorded by highly accurate electronic sensors.
