2018 Polygon Cascade 4.0 - 27.5 inch Mountain Bike

 

New for this year, the Cascade 4 enters the Polygon lineup, borrowing much of its technology from the highly popular Polygon Premier series from previous years.

Utilising a new lighter frame, the Cascade 4 is now one of the lightest mountain bikes in its category on the market. The aluminium frame is combined with reliable and durable components, which compared to other brands in the same price point makes the Polygon Cascade 4 the clear bike of choice. 

With the 27.5” wheels, the bike is not only an efficient commuter but can comfortably handle itself on mountain bike tracks and the front Suntour XCM fork validates the claim. The thicker 30mm stanchions on this model mean that the forks won’t flex under load and provide a very smooth and plush feel when riding over obstacles.

The rear Shimano Tourney rear derailleur has been improved for this year, now capable of handling the 8 speed cassette. This is then combined with the Shimano Altus front derailleur to give a total of 24 gears, enough to tackle any kind of terrain.

Braking on the Polygon Cascade 4.0 is handled by Tektro disc brakes both front and back. Having disc brakes on a mountain bikes makes a world of a difference especially when you’re riding in wet weather and need reliable braking performance.

Should you need it there are rack  mounts  on  the frame for rear baby seats or pannier racks.

To keep you connected to the ground at all times the bike comes with stainless steel spokes laced onto 27.5” double wall alloy rims - adding massive doses of strength to the wheelset.

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

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.
