Polygon Siskiu D7.0 Dual Suspension Mountain Bike

Free 14 Day Test Ride     Free Shipping Worldwide


The Polygon Siskiu D7 continues its success from previous years, as being one of the most sort after dual suspension bikes on the market, and yet, it has been again improved this year – continuing to push the boundaries in performance trail bikes.

This year the lightweight frame continues with its 120mm, linkage driven single pivot suspension system that has minimal pedal bob.  The D7 frame, like the D6, has been improved. Polygon have added a single piece linkage which has resulted in reduced lateral flex in the rear triangle and improved the linear movement and performance of the shock. Furthermore, the frame continues to internally route all gear cables, resulting in a frame with really clean lines.

The D7 does feature upgrades over the D6, mainly come in the form of branded components. Rockshox now supply their Rockshox 30 Silver Solo Air fork and its a superb addition to this bike – as the forks are known for their linear, plush and predictable feeling

The Suntour EpiXon rear air shock features a hydraulic speed lockout and rebound adjust so you can customize the sensitivity to each and every trail you encounter.

As a nod of the head to performance, it is now a double chain ring crankset, reducing the weight and unwanted duplication of gear ratios, commonly found in triple ring cranksets.

The crankset features a hollowtech spindle, external bearings, and with Shimano Deore now branding the crankarm, you can rest assure that there is the Shimano guarantee of compatibility with the Shimano Deore cassette and Shimano Deore XT rear derailleur. The clutch on the rear derailleur continues to be a well-deserved asset on the bike, removing any unwanted chain slap.

Keen observers will note that Shimano hubs have now also been spec’d on the bike, these free rolling hubs add to the reliability of the entire package.

 The Polygon Recon 4.0 was reviewed by Flow Mountain Bike Magazine. The Siskiu D7 is the new version of the Recon 4. Click here to check out the review.
