Siskiu D Range

Cross-Country Dual-Suspension Bikes


Thanks to modern geometry, Polygon's Siskiu D series takes 120mm of travel and makes it unbelievably capable. A slacker head angle, longer reach and steeper seat angle make the D series perfect for riders looking to tackle XC riding with some aggression.




1x Gear System

High-performance mountain bikes feature 1x drivetrains for their simplicity and reliability; that's just the case with the Siskiu D6 & D7. Removing the front derailleur and extra gears have removed any additional issues that may arise. Along with the problems and extra fuss, 1x drivetrains have also removed any confusion.

Instead of multiple shifters operating an excessive amount of gears, there is now one shifter. The shifters have been ergonomically designed for an optimised shifting position. Shifting gears has never been this easy.

Shimano Clutch Rear Derailleur

Shimano clutch rear derailleurs use a one-way bearing to provide extra friction when the derailleur cage is pulled forward. This style of rear mech provides an extraordinarily quiet ride thanks to more chain tension. More chain tension leads to less chain slap against the frame. The extra chain tension partnered with the unique "narrow, wide" chainring tooth profile means you can ride hard with confidence, even without a chain guide.

Lightweight Hydroformed Frame

Thanks to hydroforming, Polygon can create unique bends and tune the thickness of the metal. This means you won't have a frame that weighs a tonne because there is no excess mass where it isn't needed. Hydroforming is also what makes the frame look so damn good!

Dropper Seat Post

Dropper seat posts are the greatest invention since the wheel. At the flick of a switch, you can move the D6 & D7's seat up or down to suit the trail conditions. It will return to the perfect pedalling position every time. When descending, it is best to lower it down to get your weight back more easily and to allow the bike to move underneath you freely.

Small and medium sizes come with a 150mm dropper, while Large and Extra Large arrive with 170mm.

Hydraulic Disc Brakes

Mountain bike hydraulic disc brakes take cues from those on motorbikes but, are much smaller. Even though they are smaller, they don't lack power. With power comes modulation; gone are the days of accidentally going over the handlebars. With one-finger braking, stopping power is controllable and modulated easily by the rider for confidence in all weather and trail conditions.
