Ex Demo / 2017 Polygon Siskiu D8.0 Dual Suspension Mountain Bike - MEDIUM 17"

His Siskiu D8 is a Medium and has some small signs of use but overall in very good condition. Please check photos for damages

The Polygon Siskiu D8 received consistent, positive feedback from the industry last year. Flow Mountain Bike's review noted the D8 had "such solid performance and reliability from the components fitted to a sturdy and well-thought out frame". Mountain Bike Australia Magazine also reviewed the D8 and viewed the bike as "amazing spec for the dollars" and built around a frame that was "stiff and respectively light".

The Siskiu D8 also features the new single piece linkage but also makes full use of the thru axle capabilities of the bike. Both the front and rear of bike come supplied with a thru axle, this system is much lighter and stiffer than a traditional quick release system. 

An upgraded Rockshox Recon Gold Air suspension fork was chosen to handle the damping duties up front on the Siskiu D8. Like the silver model, the Recon Gold also employs the dual chamber design. It does also feature alloy stanchions rather than steel stanchions as on the Recon Silver, to further reduce the weight at the front end of the bike.

With a remote lock out sitting on the handlebars, you won’t need to remove your hands from the bars to operate the fork lock out feature.

A Rockshox Monarch RT rear shock, complete the Rockshox damping duties these feature the Rockshox Solo Air technology and 2 position compression rebound adjustment – perfect for almost all trail conditions

The drivetrain on the Siskiu D8 comes equipped with an upgraded 22 speed Shimano setup combining SLX front derailleur and shifters with a clutch equipped Shimano Deore XT rear derailleur. A true high performance drivetrain. The broad gear range combined with the lightweight package means this bike is also very capable on the XC race track.

Perhaps the most significant improvement on preceding models however are the incredible Mavic CrossRide wheels. They are a serious upgrade on this bike and absolutely unseen for a bike at this price point.  CrossRide wheels feature sealed bearings, alloy thru axles and carrier and unyielding double wall alloy rims -  these wheels will be your loyal companion for many many kilometres to come.

Lastly a set of Schwalbe Smart Sam wrap around this wheelset and set you up for awesome cross country riding fun.

When your bike arrives, all you have to attach is the front wheel, the handlebar and pedals, everything else has been done – the headset has been adjusted, wheels trued, pedals and seat post greased, brakes and gears calibrated, and the tyres have been pumped up (please note upon arrival, in some cases you may need to add more air to tyres).

Most companies simply sell you the bike as it comes from the factory, which will require significant know-how to get your bike on the road. Currently we are the only Australian company providing this service, and have the 14 day test ride to back it up.
