On-Road Trainer Rear Thru-Axle

Standard thru-axles often have tapered or specialized ends that don't interface correctly with the clamping mechanisms of indoor trainers. This specific axle is designed with a flat, uniform profile to ensure your bike locks securely and safely into your trainer without damaging your frame.

No, this axle is specifically engineered for 2017 and newer Giant road models that utilize the 142x12mm rear thru-axle standard. It is not compatible with older models or different axle standards.

While it is constructed from durable alloy, this axle is specifically optimized for indoor trainer use. We recommend swapping back to your standard stock thru-axle for outdoor riding to ensure the best performance and compatibility with your bike's original hardware.

You can typically find this specification printed directly on your current axle, or by checking your bike's technical manual or geometry chart on the manufacturer's website. If you are unsure, your local bike shop can quickly verify your hub spacing and axle diameter.

Installation is straightforward and generally requires the same tools you use for your standard thru-axle, typically a 6mm hex key. It is designed to be a direct replacement for your existing rear axle when setting up your trainer.
