The Garmin 135mm Thru-axle Adapter Set is designed to make your indoor training setup more versatile and secure. Many modern bikes use thru-axle rear wheels, which are not always directly compatible with traditional trainer interfaces. This adapter set bridges that gap, allowing bikes with a 135mm thru-axle spacing to be mounted safely and firmly on compatible indoor trainers. It is ideal for riders who want to use their everyday bike on the trainer without swapping wheels or compromising on stability.
Engineered to work seamlessly with Garmin and Tacx-style trainers, the adapter set helps ensure proper alignment, smooth rotation, and consistent resistance during your workouts. Installation is straightforward, typically requiring only basic tools and a few minutes of setup. Once installed, the adapter provides a solid connection that minimizes flex and unwanted movement, giving you a more realistic road feel and confidence during intense sprints or long endurance sessions. Whether you are training through winter, warming up before races, or following structured workouts, this 135mm thru-axle adapter set is a practical upgrade that expands the compatibility and convenience of your indoor training system.
