The Sight A3 boosts every rider’s All-Mountain confidence with improved descending capability, adept, sure-footed climbing, and efficient pedaling.

By re-imagining how we design bikes, our engineering department shattered the status quo with the Ride Aligned design system, addressing how a rider’s center of gravity impacts the bike’s performance and then built the Sight A3’s All-Mountain design and aluminum frame around that.

The Sight A3 offers 150mm of RockShox Deluxe Select R travel and is equipped with a RockShox Yari RC fork. The SRAM SX Eagle drivetrain transfers your power to the trail, and Shimano 4-piston hydraulic disc brakes dial in the control, all while the TranzX dropper offers size-specific drop to give you that edge, no matter the terrain.

- 6061 Hydroformed Aluminum, 150mm rear travel
- Generation 2 Gravity Tune geometry and suspension
- RockShox Yari RC motion control 160mm fork
- RockShox Deluxe Select R shock
- SRAM SX Eagle 12 speed drivetrain
- Shimano BR-MT420 4-piston hydraulic disc brakes
- Maxxis Minion DHF, DHRII EXO/TR folding bead tires

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
