Do I need an adapter for my GT?
Yes – in most cases.
Modern GT bikes often come with:
- 12 mm thru axle (common on MTB & gravel)
- 5 mm quick release (older models or entry-level)
- Boost spacing (especially on full-suspension bikes)
- Thread pitch: M12x1.5 or M12x1.75 depending on model
If your trailer doesn’t fit, you likely need an adapter.
GT models that often require an adapter
- Aggressor / Avalanche / Zaskar / Pantera (MTB)
- Grade / Transeo / Nomad (gravel & hybrid)
- Sensor / Force / Fury (full-suspension & enduro)
- eForce AMP / ePantera (e-MTB)
⚠️ Boost spacing and axle thread pitch may vary – contact us to confirm before ordering.
