About this product

The Polygon Siskiu T7 is a trail-focused mountain bike built around a hydroformed, triple-butted 6061 aluminum frame (heat-treated for added strength) with a geometry tuned for aggressive descents and efficient climbing. Up front, a RockShox 30 Silver RL fork provides 140mm of travel, while the RockShox Deluxe Select+ rear shock, custom-tuned to Polygon's Faux Bar linkage, delivers 135mm of coil-like travel via a DebonAir air spring. Stopping power comes from Shimano BR-MT420 four-piston hydraulic disc brakes, and the 12-speed Shimano Deore drivetrain (10-51T cassette, 32T chainring) handles a wide range of terrain reliably. Maxxis Dissector 29 x 2.4 tires are tubeless-ready and suited to hard-pack and aggressive cornering. An X-Fusion Manic dropper seatpost (150mm drop on smaller sizes) adds trail versatility. The tapered headset, boost hub spacing, internal cable routing, and stainless spokes round out a well-considered component package. Available in Candy Red; pedals sold separately.

What people are saying

Reviewers consistently praise the Polygon Siskiu T7 as an outstanding value in the sub-$2,000 full-suspension trail bike category, noting that its modern geometry, capable RockShox suspension, and Shimano Deore 12-speed drivetrain punch well above their price point. The aggressive trail geometry, 29-inch wheels, and steep seat tube angle earn consistent compliments for confident descending and efficient climbing. Many reviewers highlight that the frame is upgrade-friendly and looks far more expensive than it is. The most common criticism centers on the stock brakes, which reviewers describe as lacking power and confidence, with several recommending an early upgrade. Some note the bike carries noticeable weight, and a recurring suggestion is to save a bit more for the T8 trim, which offers meaningfully better suspension components.
