Polygon Siskiu D5 - Dual Suspension Mountain Bike

 

Introducing the Siskiu D5 - Polygon's newest addition to the very popular Siskiu D range which Polygon have been rolling out in Australia and globally for over 4 years now.

The D5 picks up on where the D6 from last year left off. It comes very similarly spec’d but comes with the upgraded frame which features new internal routing to keep the cables out of the way, as well as smaller finishing details that gives the bike a nice clean and refined look.

The Siskiu D5 frame is a durable yet lightweight Alloy Cross Country frame that has 120 millimetres of suspension travel to absorb any trail inconsistencies to keep you comfortable and in-control. It goes without saying that the D5 features 27.5” wheels, which provide increased performance by blending low weight together with reduced rolling resistance.

A Suntour XCM HLO, fork dampens up the front end of the bike with 120mm of hydraulically damped travel. A Suntour Raidon rear air shock provides the suspension duties out the back – both the front fork and rear shock feature a lock out, this enables you to improve performance whilst climbing or to improve efficiency on the road.

Rapid-fire Shimano Alivio shifting components promise smooth, reliable, and responsive action even in situations of extreme torque such as steep hills. With the 27 Speed Shimano Alivio drivetrain, you get a huge range of gearing for any riding scenario from high speed descents to easily climbing the steepest of hills. The Shimano Alivio rear derailleur is attached to the frame using Shimano's direct mount technology, which is a much more stable and reliable method of attaching a rear derailleur than a typical derailleur hanger. 

For stopping power, hydraulic disc brakes have been provided for by Shimano, who are undoubtedly the best name in brakes. The front rotor has been oversized to 180mm in the D5 and together with the Shimano levers and calipers, provide confidence inspired braking in all weather conditions.

A host of Entity alloy components such as handlebars, seatpost and stem, all work together to keep the weight down, the bike powerful, and the handling precise. All of these ride comfortably on a pair of super reliable Schwalbe Smart Sam tyres

We understand how important shipping is once you click "buy now", that's why we have the following policies

Australian Warehouse

All products are in stock and ready to ship from our Sydney warehouse (with the exception of preordered bikes, which have the dispatch date illustrated)
 

Next day dispatch

All orders received by 5 pm AEST will usually be dispatched the following business day. If an order is placed on the weekend or public holiday, please note dispatch will usually be the next working day. For tracked shipments, please allow 12 hours for tracking to begin.
 

Shipping of Parts, Accessories and Apparel

Economy Shipping

Express Shipping

We do also offer Express Shipping for a small additional fee on parts, accessories and apparel orders. Estimated delivery time on Express Shipping is 1 to 4 business days.
 

Shipping of Bikes

Shipping of bikes and other bulky goods is free to 85% of residences in Australia. However, some postcodes incur a surcharge starting from $29. 

Once shipped you will be issued a consignment number which can be used to track your parcel. We use Direct Freight Express for deliveries and you can track your delivery by calling 1300 347 397 or online at www.directfreight.com.au

 

We’re so confident that you’ll love our extensive range of bikes, that we’ll let you ride one as your own for a full 14 days and if you don’t like it, simply e-mail us at sales@bicyclesonline.com.au and we’ll pick it up from you, free of charge! Just make sure you keep the box so it can be re-used to send it back. Click here for more information. 

All of our bicycles come with a Free Pro Build valued at $99. This means that your bicycle will be pre built by our professional mechanics. For your convenience, safety and comfort all our bikes are fully assembled prior to delivery. The bike is then packaged back into a box for secure shipment.

 

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.

All the tools required to assemble the bike are included. 

Please note, that all bicycles whether purchased online or instore, are mechanical devices and need to be serviced regularly to ensure proper functioning. New gear and brake cables, will stretch during the initial bed-in period, and will need to be adjusted after approximately 150-300km. 

Whilst your new bicycle will have already gone through our Pro Build process, you will still need to complete some minor final assembly steps when you take your bicycle out of its box.

Please follow the video playlist below to correctly complete the setup of your new bike:

 

Assembly Time:

  • 10-15min - You have assembled bikes before
  • 15-25min - You are mechanically handy
  • 30-40min - Never assembled a bike and working with tools isn't your thing

 

Unboxing your bike:

Start by carefully opening the top flap to expose the contents. You will see the bike with plenty of protective packaging and next to the rear wheel, the saddle & seatpost, a small cardboard box where your pedals, tools, bell and reflectors are. If you ordered any other products with the bike, it is likely they were placed on the bottom of the box as well. Remove all the loose items before pulling the bike out of the box and gently placing it on the floor.

Keep the box and all the protective packaging found on the bike in case you choose to change frame sizes, upgrade/downgrade the bike, or return the bike for a full refund under the 14 Day Test Ride Policy.
