BASE MODEL

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), 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).

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.
