EXCEED YOUR EXPECTATIONS

UNBELIEVABLY CAPABLE FOR ANY XC TRAILS

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.

Enjoy a steady steering

Less flex for excellent front-end control with its tapered head tube design

Designed for an aggressive ride

A slack head tube angle, long reach, and steep seat angle to tackle any ride.

Better traction, better handling

With our Faux Bar System, Siskiu D provides you maximum traction on the rear tires for a steady handling and comfortable riding on climbs and downs.

Minimized lateral flex

Combination of the 120 mm of travel in the rear and a One-Piece Linkage System, Siskiu D reduces lateral flex and twist in the rear triangle and improves the performance of the suspension.

Wheel fit size system

Siskiu DSE comes with Wheel Fit Size System that perfectly fits the rider for an efficient ride and optimum riding experience.

A perfect riding position with dropper seat post

Comes with dropper seat post that suits your riding style and gives you a perfect pedaling position at any time.
