About this bike

The Polygon Siskiu D5 is a staff favourite, our most-affordable full-suspension bike that comes in at unbeatable value. Perfect for younger riders who are looking to push their skills on the trails or new riders looking for an entry level bike that will allow them to improve their skills.

Show full description and specs

Big thanks to modern geometry; a slacker head angle and longer reach, and steeper seat, make the Polygon Siskiu D5 XC Trail MTB bike 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 the Siskiu D5 platform to climb like a hardtail without sacrificing comfort or traction. The downs are even better when you enjoy the climb up.

Features

Accurate Steering: The frame features a Tapered headtube which offers less flex, more steering accuracy and improved front end control.

Progressive Geometry: A slack head angle, long reach and steep seat angle offer a confidence inspiring riding position to tackle any ride.

Better Traction: 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.
