Short TRAVEL, MAXIMUM FUN
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.

Progressive suspension kinematics to climb like an angel descend like a demon.
The new Siskiu's suspension is more progressive for when the trail gets rowdy. 120mm of travel designed to enjoy the climbs and demolish the downs.
Read morePolygon has revised kinematics on the Siskiu D. The anti-squat has been optimized for pedaling performance. The suspension is more progressive for when the trail gets rowdy. It has 120mm of travel front and rear, with a one-piece linkage system that reduces lateral flex in the rear triangle, leading to better shock performance. The downs are even better when you enjoy the climb up. Thanks to improved support under power, the Siksiu D platform climbs like a hardtail without substituting comfort or traction.

Stiff, Light, and Tough
Polygon's Hydroformed ALX frame is one of the stiffest, lightest and strongest frames on the market. You get a brawler on a budget
Read moreBuilt around an ALX Alloy frame with high-quality pivot bearings plus thru-axles at both ends on the D6 and D7, the Siskiu D bikes are built to ride fast and hard. Even though it is a bike ready for a brawl, it is still light and agile enough for those technical climbs. 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!

Components for confidence
Air-sprung suspension, 1 by drivetrains and dropper posts, the Siskiu series is ready to rip.
Read moreThe Siskiu series not only boasts amazing frames, but Polygon has gone out of its way to make sure the components are up to the challenge. Shimano 1x drivetrains on the D6 and D7 provide performance with simplicity. Hydraulic discs with tonnes of power and modulation are there more than ready to slow you down from warp speed.
Air sprung suspension is perfect for achieving the right setup for any rider. The larger length dropper is ideal for getting the saddle out of the way after cresting the climb and are ready to descend. With the seat out of the way, you can get further back on the bike and ride confidently.

Refined geometry for an exciting ride
With a steeper seat angle, longer reach, and slacker head angle, the Siskiu is ready to shred.
Read moreSiskiu D is designed to make climbing as fun as descending. A 67° head angle provides enough stability on the downs while retaining an active front wheel on technical climbs. A steeper seat tube angle places a rider more centered in the bike, naturally placing more weight on the front wheel. You, the rider, spend more time enjoying the ride instead of uncomfortably on the front of the saddle.
Short chainstays lead to the Siskiu D being nimble and agile over the trail. Lifting the front wheel off drops and pumping through terrain has never been this easy. The Siskiu rewards riders who are active on the trail, riders who skip through the trails. It enhances the playfulness of cautious riders and brings an innate sense of fun to every ride.

Rider Size Specific Wheel Size
Wheel sizing to suit smaller riders on smaller sizes. Every rider gets the optimum experience no matter what their size. The Siskiu D series comes with 27.5" on S/M and 29" on M/L/XL.
Read more29-inch wheels provide better rollover for rough terrain thanks to the shallow attack angle and increased momentum. They also maintain speed better throughout a ride and increase traction thanks to a greater contact patch. However, for shorter riders with shorter legs, there can be some downsides.
Riders with a shorter stature may not be able to get their weight off the back of the bike without the rear tire hitting them. A bigger wheel also requires more input from the rider which, may end up becoming overwhelming. This could hinder the riding experience for some riders. While the D5 features agile 27.5-inch wheels on all frame sizes, Polygon has taken the Siskiu D6 and D7 bikes to another level with their Wheel Fit Size System. Size Small is optimized around 27.5 wheels. Medium is available in 27.5 or 29 depending on height and leg length. Large and Extra Large are available in 29 only.

Entry Level Price, Higher Level Performance
Polygon owns the manufacturing process from inception to quality control. We have lower costs so you have greater savings.
Read moreThe Siskiu D7 is proof you don't need to break the bank to get into the sport of MTB. There is no compromise on quality thanks to Bikes Online selling directly to the consumer. Direct to the consumer misses the middle man and the associated costs. We pass the savings onto the rider.
Thanks to these savings, riders can get a bike that will grow with their riding and is fully upgradable as they gain more skills.
Features
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 optimized 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 pedaling 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.
