The all new Cascade 3 is your ticket to confident off-road riding without the fuss. Its lightweight ALX alloy frame rolls on fast and stable 27.5” or 29” wheels, paired with 100mm of front suspension to smooth out roots and bumps. Shimano’s simple 1x8 drivetrain keeps things easy to shift and low-maintenance, while hydraulic disc brakes deliver all-weather stopping power. Whether you're hitting local trails or just cruising the bike path, it’s built to handle it all — with room for racks, fenders, and future upgrades.
ADVENTURE STARTS HERE
The Cascade 3 is built for everyday riders who want a bit more from their bike — more comfort, more control, and more freedom to explore. Whether you're sticking to bike paths, cutting through the park, or tackling light trails, its wide tyres, front suspension, hydraulic disc brakes, and simple 8-speed drivetrain make every ride smoother, easier, and more fun.
LIGHTWEIGHT ALLOY
Polygon’s ALX aluminium frame hits the sweet spot between strength, weight, and ride comfort — giving you performance that’s usually reserved for higher-end bikes. Internal cable routing and clean tube shaping give it a modern, premium look without the premium price tag. Tough, lightweight, and ready to roll.
COMFORTABLE GEOMETRY
The Cascade 3 uses stable, upright geometry that puts you in a comfortable and controlled riding position — ideal for everything from bike paths to light trail rides. Its frame balances predictable steering with easy maneuverability, making it a great fit for riders who want both comfort and confidence on varied terrain.
100MM FRONT SUSPENSION
The SR Suntour XCE28 front suspension helps absorb bumps and rough surfaces, giving you more control and comfort on bike paths, gravel, or light trails. Preload adjustment lets you fine-tune the feel based on your weight or riding style.
SHIMANO ESSA DRIVETRAIN
The updated Shimano ESSA 1x8 drivetrain offers reliable, intuitive shifting with a wide 11–45T cassette for tackling climbs or cruising with ease. With just one shifter to manage, it keeps things simple, smooth, and focused.
HYDRAULIC DISC BRAKES
Hydraulic disc brakes give you smooth, reliable stopping power in all conditions—even in wet weather. They’re easy to control and require less hand effort than mechanical brakes, making them great for new and returning riders.
ROBUST & VERSATILE WHEELSET
Tough double-wall alloy rims paired with 2.25-inch tyres deliver stability, grip, and comfort. Confident cornering, smoother rolling on pavement, gravel, and dirt, plus durable construction that shrugs off knocks, keeps you riding farther with fewer worries about maintenance or reliability.
