2019 Polygon Strattos S2 - Shimano Claris Road Bike


Shipping Calculator

In many ways it is more difficult to design bikes for entry level riders than it is for the higher end, riders in this category you want a bike that functions well and aren’t sold on advertising gimmicks that provide little if any on- road benefits. It is for this reason that a lot of time was spent in the lab, working out how to provide a bike that is stiff and responsive, yet at the same time provides excellent value for money.

With the Strattos S2, Polygon have reached a critical balance point – trading weight with durability, speed with comfort, and performance with reliability. The overall package is indeed a category killer.

The heat treated, butted alloy frame doesn’t require an aggressive posture like pure racing bikes, and is instead a slightly more upright comfortable ride – these frames usually termed “endurance frames” are designed for riders doing rides like Bay in a Day or Sydney to the Gong.  It’s during these rides that the frame also delivers with predictable handling. Often competitor road bikes in this category are based on race frames, which can feel quite twitchy especially during descents, where the Strattos remains composed and sure footed.

Those using the bike as a commuter, will also appreciate the handling characteristics, and Polygon have backed up its commuter credentials by adding rack mounts to the frame for panniers and luggage.

The fact that the cables are internally routed, further add to the look of the bike.

On the front end of the frame, Polygon have fitted a carbon fibre fork. This fork not only reduces the overall bike weight but most importantly dampens road vibrations, causing less fatigue to your body and keeping you fresh - mentally and physically. For this new version of the bike, the fork also includes as carbon steerer as opposed to alloy which was on the previous version of this bike.

The drivetrain is powered by Shimano. The Shimano Claris is the first in the line-up of Shimano’s dedicated road group sets. Clean crisp shifts are combined with a range of gears almost identical to the higher end group sets.

The crankset and bottom bracket on the Polygon Strattos have also been carefully chosen with efficiency and lightweight in mind. This is an often overlooked part of the bike, yet it is through here that all the power is transferred through the frame.

Instead of using a heavier and cheaper sealed bottom bracket and crankset seen so often on entry level bikes. Polygon have specified a Hollowtech bottom bracket and crankset which shaves precious weight from the bike and stiffens up the bottom bracket, improving performance. You will usually only find similar technology on bikes twice or three times more expensive.

All of these features mean that this bike will outperform the competition and more importantly your expectations.

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.
