The Cascade 5 is Polygon's entry-level hardtail trail bike, built around an ALX XC aluminum frame with internal brake and shifter routing. It pairs a 100 mm Suntour XCM32 coil fork with 29-inch wheels and 2.25-inch tires, plus hydraulic disc brakes that are rare at this tier. It suits new riders and casual trail riders who want a dependable, low-maintenance bike rather than a race machine. Against pricier hardtails it gives up air suspension, a lighter frame and a clutched drivetrain, but the core package is sound.
