This Bundle Contains: 1 Tacx Galaxia Indoor Retractable Bicycle Rollers + 1 Tacx Sweat Set + 1 Signature Series Resistance Band. Garmin Tacx Galaxia. Take your training indoors with the Tacx Galaxia roller. Featuring a patented swing system, this advanced roller can absorb your forward and backward accelerations, so you can ride hard while staying firmly in place. The Galaxia relies on a swing system that ensures the rollers can swing forward and backward. When you start to sprint, switch pace or stand on the pedals, the system absorbs the sudden movement, so you don’t derail. Tacx Sweat Set. Indoor training means plenty of perspiration. This set contains everything you need to protect your bike and keep yourself comfortable while you ride. This convenient cover protects your bike from sweat while giving you access to your smartphone while you ride. Made from absorbent material and featuring a clear pocket for your phone, it fits most bikes and mounts easily. The pocket is suitable for different phone sizes, with a maximum length of 138 mm and maximum width of 68 mm. Signature Series Training Resistance Band. 78 Inches Long, 2 Inches Wide. Compared with normal-sized bands, our fabric resistance bands' length is more suitable and flexible so it can help you more effectively achieve full-body extension and enhance exercise. You can fold for more tension, tie a knot for a loop band or take a couple wraps around your hands for a secure grip.
