Big thanks to modern geometry; a slacker head angle and longer reach and steeper seat, makes the Polygon Siskiu D series series unbelievably capable for riders looking to tackle XC riding with some aggression. The anti-squat has been optimized for pedaling performance and the suspension is more progressive for when the trail gets rowdy. We improved support under power, enabling Siksiu D platform climbs like a hardtail without substituting comfort or traction. The downs are even better when you enjoy the climb up.
