    Feels really stable
    Thanks to the thoroughly modern geometry and sizing, the Siskiu T8 is a bike that can be ridden hard straight from the get go. It's one of the best budget mountain bikes out there.

    Exceptionally capable

    Competent climber
    It performs well in tight, technical terrain and long, steep grinds. The quality component spec, specifically the drivetrain, and tyres, helps bolster its solid climbing performance.

  • 5 stars Great bike, easy setup!
    "The T8 shipped fast, was packed beautifully, easy to put together and rides really well! The components all function very well and the bike was setup nicely from the factory. This is the absolute best value out there for a full suspension bike with these components."

BASE MODEL T6

The T6 is the base model out of the Polygon Siskiu T series - spec’d to be capable, right out of the box. Coming with reliable components and the same ALX alloy frame as its older siblings, this trail tamer is perfect for those who are looking to upgrade their hardtail, beginner mountain bikers, or those who want a trail bike that doesn’t break the bank. Compared to the T7 (the next tier up), the T6 has the same fork(RockShox Recon Silver RL), but different brakes (2-piston vs 4-piston), rear shock (X-Fusion O2 PRO vs RockShox Deluxe Select Plus), and drivetrain (10 vs 12-Speed Deore).

Proven
INTERMEDIATE T7

TheT7 is the intermediate model out of the Polygon Siskiu T series - spec’d with slightly better components compared to the T6; although, it still shares the same fork and ALX alloy frame (frame is the same on all models). This hard-hitter is perfect for those who want to take it a step up from the T6. Other than coming with the same fork (RockShox Recon Silver RL), the T7 is equipped with mid-tier brakes (4-piston vs 2-piston), rear shock (RockShox Deluxe Select Plus vs X-Fusion O2 PRO), and drivetrain (12-Speed Deore vs 10-Speed Deore).

Best-Seller
HIGH-END T8

The T8 is our best selling trail bike - spec’d with higher end components relative to the T7; however, still has the same ALX alloy frame as the rest. If you’re someone who is looking for more premium components straight out of the box, the T8 is an excellent choice. With a complete component upgrade from the T7, the T8 comes with even better brakes (4-piston F/R vs 4/2-piston F/R), rear shock (Fox Float DPS vs RockShox Deluxe Select Plus), and drivetrain (12-Speed SLX vs 12-Speed Deore).

Top Tier
ULTRA HIGH-END T9

The T9 is the top dog in the T lineup. Spec’d with ultra high-end components and the same ALX alloy frame as the rest, you’ll soon be wondering if you’ll ever need another MTB again. If you’re someone who is performance oriented and wants the creme de la creme, this trail demon is a big step up from the T8. From the stiff and light 36 performance elite fork to the podium producing X2 rear shock, buttery smooth XT drivetrain, and hard-hitting TRP 4-piston brakes, you’ll be kitted out with the best.

  • 01 - Stable
    Given a healthy dose of slack (65-degree head angle), the T will have you feeling confident on the descents - maintaining high-speed stability when the trails get hairy.
  • 02 - Confident
    Coming with a longer 460mm reach (size: M), the Siskiu builds on the MTB mantra 'long and slack'. You'll get that added stability as you bang it down those chunky descents.
  • 03 Efficient
    With the steep 76.7 degree seat tube angle, you'll be more centred over the bike, which improves the climbing efficiency whilst enhancing the handling on those steep pinches.
  • 04 - Playful
    With the short 425mm chainstay, the Siskiu T is fun and playful - allowing you to flick it out of corners and manoeuvre tech sections with ease.

FAQ
Is the Polygon Siskiu T good?

With over 1500+ positive buyer reviews and numerous industry reviews raving about punching well above its weight, the Polygon Siskiu T is changing the industry standard.

What type of bike is the Polygon Siskiu T?

The Polygon Siskiu T is a versatile all-round trail bike. This particular dual suspension mountain bike features 140-150mm up front and 135-140mm in the rear (depending on the size). With a 65 degree head tube angle and a short 425mm chainstay, the T is nimble enough for technical terrain and slack enough for moderately chunky descents.

Can the front fork have its travel lengthened?

Yes, but only by 10mm. Any more and the additional forces on the head tube and frame can cause a frame failure.

Can I fit a coil shock?

Yes, but the frame’s suspension is not designed to work with a coil spring’s characteristics; thus, it will not feel supportive or work well past 50% travel stroke.

What is the widest tyre/tire that fits on this frame?

2.5 - 2.6” is the largest. Please keep in mind that a rear tyre that is too large can make cornering less efficient and can bring a squirmy feeling.

What are the weights of the Siskiu T bikes?
  • The T6 is approximately 16.7kg - 36.8lbs
  • The T7 is approximately 16kg - 35.2lbs
  • The T8 is approximately 15.8kg - 34.8lbs
  • The T9 is approximately 16.1kg - 35.5lbs
What size are the dropper posts for the Siskiu T?

Seat tubes on the whole range have been significantly shortened to allow for 150mm dropper posts on SM and MD frames, and 170mm on LG and XL.

What is the difference between the Siskiu T and Collosus N?

The Siskiu T is a trail bike and the Collosus N is an Enduro bike. The T is designed to be more versatile (lighter, not as slack, and shorter), whereas the Collosus N is heavier, more slack, and longer - providing you with enhanced stability on gnarlier (steeper & chunkier) terrain.
