GARMIN Tacx Galaxia Advanced Roller Trainer

For cyclists who want to refine balance and pedal stroke indoors, the Garmin Tacx Galaxia Advanced Roller Trainer turns any room into a dynamic training space. Its parabolic rollers keep the bike centered while the unique swing system absorbs forward and backward acceleration, letting you ride naturally without fear of falling off. No power outlet needed—just unfold, place your bike, and start spinning.

• Warm-up and cool-down before or after outdoor rides
• Balance and technique training for road cyclists and triathletes
• Basic indoor cycling when weather or time limits outdoor riding
• Rehabilitation and low-impact leg workouts

Good to know

The Galaxia Advanced is part of the Tacx Roller Series, known for durability and smooth operation. It works with any bike with 26" to 29" wheels, including most road, gravel, and mountain bikes. Since it's non-smart, you can pair it with any speed or cadence sensor and your favorite training app for basic metrics, but it doesn't transmit data itself. No assembly required—just unfold and ride.
