Developed, tested and tweaked by Sam Reynolds himself, the new Polygon Trid continues its successful formula combining a bomb proof alloy frame with a spec sheet you can depend on. 

The AL6 Alloy frame has won many a podium and is equipped with all the technology and features you expect from a top of the line Dirt Jumper. Tapered headtube, short chainstays, horizontal dropouts and wide frame tubes for improved rigidity. Despite all of this, the Polygon Trid frame still comes at an incredible 1.9kg for the frame alone, so important when you’re trying to spend as much time as possible in the air.

Shimano BR-M365 hydraulic disc brakes are provided front and rear, but its not uncommon to see the front brake and rotor removed for dirt jumping – strictly for off road use of course.

The X Fusion slant air fork is quickly becoming the dirt jumper fork of choice. The fork features super wide 34mm stanchions combined with adjustability, which has often been the bug bear of many dirt jump forks, and the slant has rebound and compression adjustment (check). Put all together with the quality that can only come with one of the biggest fork factories in the industry.

• X-Fusion Slant DJ 26” Air fork with thru-axle and 34mm stanchions

 All tools are supplied. If you are unsure of anything during assembly please contact us. 

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.
