Aggressive XC or down-country, whatever you call it, if you ride trails and like the up as much as the down, Polygon had you in mind when making this bike. With a little less travel than the T-series, the Siskiu D-series are designed for fast and flowy XC riding. Suntour suspension up front and RockShox out back, pari well with dialed in geometry to keep you glued to the trail. The 11-speed Shimano Cues drivetrain has enough mechanical advantage to take the edge off of the steepest climbs. And Shimano 2 piston brakes keep your speed under control in all conditions.

Suntour Raidon front fork has 120mm of air-sprung travel, a lockout for climbing and rebound adjustment for that glued to the ground feeling
RockShox Deluxe Select+ rear shock has been custom tuned to match the Siskiu’s geometry and Polygon’s Faux Bar linkage. Equipped with the highly tunable DebonAir™ spring that offers a coil-like consistent feel throughout the travel
One piece suspension linkage increases stiffness while reducing weight. Delivering a ride that is poppy and supportive, with excellent small bump compliance, yet is still efficient in the climbs
11-speed Shimano Cues drivetrain provides fast accurate shifts even in rough terrain
The Cues line provides reliable performance, durability, and easy maintenance – with cross compatibility across the line
Shimano MT201 hydraulic disc brakes offer plenty of stopping power in all conditions
ALX Alloy frame is uses hydro-formed, triple butted 6061 aluminum that has been heat treated for improved strength and durability
FWG frame geometry has been optimized for aggressive trail riding, steep descents, and comfortable climbs
Tapered head tube broadens towards the bottom leading to better force transfer from the fork to the frame. The increased stiffness of the tapered head tube provides improved handling
Internal cable routing keeps your cables safe from trail hazards and has a nice clean look
Polygon’s wheel fit system equips small bikes with 27.5in. wheels, and medium to extra large bikes with 29in. wheels. Polygon feels this balance offers the rider the most efficient power delivery and ergonomics for their size
Tranz-X dropper posts with internal cable routing, give you somewhere to sit when you need it and get your seat out of the way when you don't. 29in. – 170mm drop. 27.5in. – 150mm drop
Boost hub spacing offers improved rigidity and strength, and paves the way for easy upgrades down the road
Maxxis Rekon has a versatile, fast rolling tread pattern that bites into hard and soft terrain with ease and has taller side lugs for extra grip in the corners
Short chainstays make the bike feel nimble on the trail and flickable in the corners
