Professional-grade durability with a robust steel frame ensures it can withstand intense training sessions and heavy use over time. However, it's worth noting that the compatibility with certain bike makes and models isn't guaranteed, so checking the compatibility guide is recommended.

Connectivity is another strong point, as it easily pairs with smartphones, tablets, computers, or GPS bike computers. The unit supports popular cycling apps like Zwift and Wahoo RGT, providing an engaging training environment. On the downside, the trainer is relatively heavy at 19 kilograms, which could affect portability and storage.
