Polygon Heist X2 Text Review

Crafted from AL6 Urban Cross aluminum and featuring a QRx135 rear axle, the Heist X2 blends a lightweight yet durable frame platform with clean internal cable routing and mounts for racks and fenders. Size options (S, M, L, XL) accommodate riders roughly from 150 cm to 190 cm, with geometry offering a 71° head tube angle and 74° seat tube angle, 440 mm chainstays, 415 mm reach, and a bike weight around 13.9 kg (30.6 lbs).

Equipped with a dependable 2×8 Shimano drivetrain—Altus SL-M315 shifters, Acera RD-M360 rear derailleur, Tourney FD-TY710 front derailleur, Prowheel alloy crank (46/34T), and Shimano CS-HG200 12-32T cassette—this setup offers a wide gear range suitable for brisk commutes and light trail sections. The chain is a reliable KMC Z-8.3.

Comfort is a hallmark feature: the Suntour NEX fork provides 63 mm of travel with preload adjustment to soften rough surfaces, while the upright handlebar and ergonomic geometry relieve long-ride fatigue. Add to that the WTB Riddler 700×45C tires, offering low rolling resistance and cushioning over mixed terrain.

Braking is handled by high-performance hydraulic disc brakes (Tektro M275 on newer 2025 spec; unspecified “high-performance” model on earlier) with 160 mm rotors front and rear—delivering responsive, modulated stopping even in adverse conditions. Steering is stable and responsive thanks to the 700 mm Entity Xpert handlebar and integrated sealed-bearing headset.

The alloy double-wall 700c wheels pair with WTB Riddler 45C tires to deliver a taut, rolling feel that still offers enough grip for loose surfaces. On top of that, the Entity Steel-bodied saddle and 27.2 mm offset seatpost provide dependable comfort, though riders seeking long-distance plushness might wish for a padded upgrade.
