Key suspension refinements:
- Increased anti-squat for improved pedalling efficiency on climbs
- Lower leverage rate for enhanced small-bump sensitivity

This configuration supports controlled descending on root networks, rock gardens and steep terrain while maintaining efficiency when climbing under motor assistance.
Adjustable Geometry and Ride Tuning
The Rail+ allows for geometry and suspension adjustments to suit different riding styles and terrain:
- Mino Link: Fine-tune bottom bracket height and adjust head tube angle by 0.5°
