The new 2018 Xtrada 8 is Polygon's top of the line hardtail alloy mountain bike and replaces the extremely popular Polygon Siskiu 7 from previous seasons. With several thousand of the Polygon Siskiu 7 sold globally last year, this spec level bike has been Polygon's most popular hardtail mountain bike to date. Polygon has listened to customer feedback and released the Xtrada 8 with some impressive upgrades such as a new Boost compatible frame, a better suspension fork, better gears and updated brakes.

The ALX super light 6061 hydroformed aluminium frame uses heat treated, hydroformed and butted tubing to give an optimal strength to weight ratio. The tapered headtube provides stable, front-end precision and the new Boost hub spacing on this frame allows for a stiffer wheel with more tyre clearance. The Boost system has also allowed Polygon to shorten the chainstays, which makes the back of the bike a lot easier to flick around corners. The frame comes internally routed, which provides cleaner lines to the bike and also reduces the chances of any cables getting snagged on trees or rocks while riding. Polygon is so confident in the performance of this frame that it has a lifetime warranty.

The Xtrada series utilises Polygon's new Wheel Fit Size System whereby each frame size is paired with the wheel size that best fits the rider and sets them up for optimal efficiency and power transfer. We pair 29˝ wheels with 18.5˝ and larger bikes, and more proportional, better-fitting 27.5˝ wheels for 17.5˝ and smaller bikes.

The Xtrada 8 build kit takes a step up, opting for Shimano's top of the line 1 x 11 XT M8000. The performance of the new XT M8000 is flawless - crisp and easy shifting, extremely durable and an all-day workhorse. The huge 11-46 tooth cassette means you won't miss having a double ring up front and you will have plenty of range for powering up long climbs. The clutch mechanism, which can be enabled and disabled with the flip of the grey lever at the top of the derailleur's parallelogram, is now externally adjustable with a 2mm hex key, a feature that allows riders to easily fine tune the amount of retention to their liking.

The suspension duties on the Xtrada 8 are handled by the new 2018 Rocksox Recon RL Solo Air fork which now benefits from the trickle-down technology of Sektor's stiff chassis and Reba's lightweight, motion control dampening. It features a15mm thru axle and a Lockout switch on the fork's leg to rapidly change from Open to Lock position and transform the way the bike behaves on the trail.

Completing the bike are Shimano M365 hydraulic disc brakes, a set of Entity XL2 wheels wrapped in Schwalbe Tough Tom tyres and a lightweight alloy Entity expert cockpit and Entity saddle and seatpost. If you are looking for a racing quality bike with durable and dependable components, the Polygon Xtrada 8.0 is the perfect bike for you.
