Rating: (4.7/5)

Lately, I’ve been watching a lot of videos about trail riding. The obscured views by the trees and the reliance on riding experience and road judgment make it an exhilarating experience. I want to try trail riding.

So, I found the Polygon SISKIU T8. It’s a highly cost-effective bike, perfect for beginners, but even experienced riders can handle it perfectly. I’m looking forward to how it performs on the trails.

Now, let’s analyze the riding experience, main features, components, specifications, and other versions of the Polygon SISKIU T8. In the latter part of this article, we will also compare it with several other top bike models. If you want to know more about bike reviews, feel free to follow us.

Riding Experience

I was eagerly anticipating the performance of the Polygon SISKIU T8, so I booked my flight and reserved a hotel through IHG to come to Bromont: Montagne d’Expériences.

I chose the La Vingt (Haut) trail in Bromont: Montagne d’Expériences. This trail is 2159ft long with an overall downhill trend and a 367ft altitude drop. The road is rough, with many loose stones and dry branches, and there are steep uphill and downhill slopes. These factors had a considerable impact on my ride.

Trail Riding

I set off, standing up to accelerate, and using the dropper to lower the seat height to avoid hitting my legs on the saddle. And I kept accelerating, flying through the forest, feeling the excitement of trail riding. I could sense the tranquility and freedom of the woods.

During downhill sections, I used the TEKTRO HD-M745 4-PISTONS HYDRAULIC DISC BRAKES to reduce speed, avoiding any mishaps in the winding corners. I firmly gripped the ENTITY XPERT handlebar to better control the entire bike.

For uphill sections, I adjusted the SHIMANO SLX RD-M7100-SGS DIRECT ATTACH rear derailleur to the smallest gear ratio. I stood up again to accelerate, lowered the seat height, and then powered through the uphill, adjusting my posture. The 135mm rear travel and 150mm front travel absorbed the shocks, providing me with great comfort and excitement.

When I reached the corners, I controlled the ENTITY XPERT handlebar and, on the ENTITY XTENT saddle, adjusted my center of gravity with my legs to lean the bike and find the best support position. Then, I powered through, skillfully completing each corner with confidence, thanks to the PERFORMANCE TIRE.

Is that all?

The Polygon SISKIU T8 comes with an ENTITY XTENT saddle. It has a very soft material, and I felt very comfortable sitting on it, without any stiffness in my hips. The central groove effectively relieves pressure on sensitive areas, providing a relaxed and comfortable sitting experience.

It is equipped with PERFORMANCE TIRE tires, available in two sizes. Based on my body condition and preference, I chose 29X2.40 (the other option is 27.5X2.40). These tires offer powerful traction and braking capabilities, allowing me to ride fast and brake promptly in emergencies, ensuring my safety.

Specifications

The Polygon SISKIU T8 is an exceptional full-suspension mountain bike designed for off-road trails. It features a sturdy aluminum frame and a FOX 34 RHYTHM fork with 135mm rear travel and 150mm front travel, providing powerful suspension for a comfortable ride.

Additionally, the Stack/Reach Ratio of this bike is 1.32, indicating good flexibility, and its 65.5° head tube angle ensures a stable ride.

In summary, riders can experience a comfortable and smooth ride, and the TEKTRO HD-M745 4-PISTONS HYDRAULIC DISC BRAKES offer reliable braking in case of emergencies.

Other Versions

After several tests, we gained a deeper understanding of this bike. It is an outstanding hardtail mountain bike.

However, many riders have their own performance requirements or component preferences, so we conducted further investigations with bikes of the same type.

Polygon SISKIU D5

The Polygon SISKIU D5 weighs 36.8 lbs, which is heavier than the Polygon SISKIU T8(33.5 lbs), potentially causing some hindrance during rides. The Polygon SISKIU T8 offers two sizes for the wheel, 27.5″ and 29″. The 29″ wheels provide better terrain clearance, while the 27.5″ wheels offer great agility. Moreover, the Polygon SISKIU D5 only has 120mm front travel and 120mm rear travel, while the Polygon SISKIU T8 boasts 150mm front travel and 135mm rear travel, providing stronger suspension for a more comfortable ride.

Additionally, the Polygon SISKIU D5 has a 2×9 drivetrain, which is not as smooth as the Polygon SISKIU T8’s 1×12 drivetrain. The 1×12 drivetrain offers smoother gear shifts, and a wider gear range, and effectively prevents chain drops. So, if you prioritize a more comfortable ride, the Polygon SISKIU T8 is a great fit. If budget is a concern, the Polygon SISKIU D5 would be a better choice.

What do we like about it?

Polygon SISKIU T8 vs Diamondback Release 29 2

The Polygon SISKIU T8 offers slightly better suspension, but the Diamondback Release 29 2 is priced nearly $1000 higher than the Polygon SISKIU T8. The Diamondback Release 29 2 comes with DB CNC Platform pedals and Ergon GE10 Evo Lock-On grips, which greatly facilitate user purchases and save time.

Polygon SISKIU T8 vs CUBE STEREO ONE22 HPC TM 29

The Polygon SISKIU T8 weighs 33.5 lbs, slightly heavier than the CUBE STEREO ONE22 HPC TM 29 which weighs 29.8 lbs, which may cause some inconvenience for riders. This is because the CUBE STEREO ONE22 HPC TM 29 has a carbon frame, while the Polygon SISKIU T8 has an aluminum frame, and carbon frames are generally lighter. However, they are more prone to breakage from side impacts, while aluminum frames are sturdier.

Moreover, the Polygon SISKIU T8 offers better suspension and more size options for the wheel. However, the CUBE STEREO ONE22 HPC TM 29 can reach a faster speed of 26mph. Additionally, in terms of geometry, the CUBE STEREO ONE22 HPC TM 29 has a larger Stack/Reach Ratio, providing a more comfortable riding experience.

In conclusion, if you want a lighter bike, the CUBE STEREO ONE22 HPC TM 29 would better suit your needs. If you prefer a bike with better suspension and sturdiness, the Polygon SISKIU T8 would be more suitable for you.
