Setup Instructions
1. Trainer Installation
- Remove the indoor trainer, support feet, bolts, and the 5mm hex key from the packaging box.
- Place the trainer on a stable ground, ensuring no obstacles or dangerous objects are around and there is enough space to deploy the trainer.
- Align the mounting holes of the trainer with those of the support feet according to the left/right markings.
- Install the bolts and hand-tighten them initially.
- Use the 5mm hex key to tighten the bolts in a diagonal sequence.
- Plug the trainer into the power supply; the indicator light on the casing will light up.
Note: The support foot with the threaded hole closest to its edge must be positioned on the non-drive side of the trainer.
2. Cassette Installation
Before installation, prepare your cassette, wrench, and sleeve.
- Before installing an 8/9/10-speed cassette, first install a 1.85mm freehub spacer. This spacer is not required for 11/12-speed cassettes.
- Put the cassette onto the freehub in order from big to small size accordingly, paying attention to the alignment of the freehub spline.
- Install the cassette cover and tighten it roughly by hand.
- Wrap the cassette with the chain, then insert the cassette sleeve and use the cassette wrench to tighten the cassette again.
3. Quick Release Adapter Installation
- The quick release cap on the freehub side has been installed by the manufacturer.
- Choose the quick release according to the specification of your bicycle, and insert the quick release adapter into the non-drive side of the trainer.
- Insert the quick release skewer into the non-drive side of the trainer; insert the conical springs at each end of the quick release skewer separately, with the tips facing inward, and then screw on the nuts.
4. Attaching Your Bicycle (Quick Release)
- Shift your bicycle chain into the smallest sprocket in the front and rear.
- Release the rear brake, open the quick release skewer, lift the bicycle frame, and then remove your rear wheel.
- Push the quick release skewer on the trainer to the "open" mode, seat the bike on the trainer, and then align the chain with the smallest sprocket on the trainer.
- Lift the front wheel up while pressing down on the saddle to ensure the bicycle is fully seated on the trainer.
- Tighten the quick release nuts while turning the quick release skewer on and off frequently until resistance is felt.
- Lock the quick release skewer and wiggle the bicycle frame to ensure that the frame does not fall off from the trainer.

5. Thru-Axle Adapter Installation
- Use a 5mm allen wrench to unscrew the quick release cap on the freehub side counterclockwise.
- Screw on the HG thru axle end cap and tighten it using a 17mm open-end wrench.
- Choose the thru-axle according to the specification of your bicycle, and insert the thru-axle adapter into the non-drive side of the trainer.

6. Attaching Your Bicycle (Thru-Axle)
- Shift your bicycle chain into the smallest sprocket.
- Release the rear brake, remove the thru-axle, lift the bicycle frame, and then remove your rear wheel.
- Align the rear axle with the trainer's axle hole in the center, insert the thru-axle, and then align the chain with the smallest sprocket.
- Lock the thru-axle and wiggle the bicycle frame to ensure that the frame does not fall off from the trainer.
7. XDR Freehub Installation
SRAM XDR freehub and thru-axle end caps need to be purchased separately.
- Use a 5mm allen wrench to unscrew the quick release cap on the freehub counterclockwise.
- Pull out the original freehub.
- Insert your XDR freehub into the trainer, turn it counterclockwise and keep pressing the freehub and detent of the freehub until the freehub is fully installed in place.
- Screw on the thru-axle cap and use a wrench to lock it in place.
- Choose the thru-axle according to the specification of your bicycle, and insert the adapter of the thru-axle adapter into the non-drive side of the trainer.
Operating Instructions
