There are two categories of cyclists: there are those who clean the road bike after every ride and does not use it when it's wet for the fear of getting it dirty and then there are those who are always "on the road" regardless of the weather and temperatures during the different seasons. The selection of products are designed for the first but also for the workaholic that - in spite of themselves - are forced to fall back on the trusty indoor trainer, for at least during the winter season. The Indoor Trainer is the most convenient and effective solution to maintain a good level of fitness even when the days are too short and cold, they greatly reduce the time of riding. Thanks to rampant Bluetooth and ANT+ technologies also the indoor training no longer enforces the interminable sessions counting down the minutes but has become an interactive engaging experience, challenging and therefore more lucrative. The top models use a real time simulation showing you the path with the instantaneous slope variations directly connected to the route reproduced on the pc or tablet and direct transmission of motion - an indispensable feature to make the riding realistic even in the absence of a real road surface - which guarantees maximum silence and extremely high intensity efforts can be achieved. Even the traditional rollers are often interfaced with Apps and Software specially developed to track workouts, draw graphs, reports and statistics. Among the innovations of recent years we should not forget the free standing rollers, foldable and space saving platforms that allows you to ride and balance on three tapered rollers with complete freedom, staying on the bike without the need to disassembling anything. All you need is some speed and balance and you don't have to worry about anything else. If at first you had problems of finding the will to ride on the indoor trainer, these new technologies will definitely get the motivation going.
