Industry Reviews

 

The new D6 – Polygon’s best value XC / down-country machine of the Siskiu D line. Capitalizing on extensive R & D, state of the art testing facilities, and feedback from top-level riders, the Polygon Siskiu D6 defies what an outstanding value dual-suspension mountain bike is capable of. This year’s host of upgrades tick all the boxes for those looking for a bike with modern geometry, great XC pedaling efficiency, and all-mountain capability.

The D6 is built around a lightweight, ALX aluminum boost frame that boasts a modern rider’s modern geometry. The bike now has a slacker head tube angle, more extended reach, lower BB, and shorter chain-stay to boost your climbing performance or descend, no matter the distance, technicality, or gradient. Polygon has also revised kinematics on the Siskiu D. The anti-squat has been optimized, and the suspension is more progressive. It has 120mm of travel in the rear, with a one-piece linkage system that reduces lateral flex in the rear triangle and improves the shock’s linear movement and performance. The frame now also comes with room for a water bottle mount.

The D6 comes with a Tranz X dropper post with 150mm (S-M) / 170mm (L-XL) travel and remote lever. Dropping the seat allows you to shift your weight around. This way, you can find the best possible position to descend’a position often blocked by a high seat post and saddle. Being in a better position results in greater control over your bicycle, which gives you more confidence to go faster. And faster ‘ usually ‘ translates to more fun!

An upgraded full Shimano Deore 1 x 10 drivetrain powers the D6 with a Shimano Deore rear derailleur with a clutch and a massive 46T rear cassette, providing plenty of range glide up those steep climbs. The Shimano Deore Crankset allows for quality and power while continuing the clean looks of the bike.

Dampening duties on the D6 is provided by an SR Suntour XCR 32 front air fork with thru-axle for added stiffness and cornering control. This is combined with a dependable X-Fusion O2 Pro air shock on the rear, offering smooth-riding and great pedaling support. The bike rolls on a pair of wide 25mm rim Entity X15 double-wall wheels and Entity Spiderbait 2.25″ tires, giving you loads of traction for climbs and hitting the berms.

If you’re looking for a bike to do it all with killer style and a dependable, high qualitytrail-ready components list, then the Siskiu D6 is the bike for you!
