Built around 27.5” wheels, the Big Seven 15 feels agile and responsive, perfect for smaller riders or those who prefer a nimble handling feel. Merida’s updated geometry features a longer reach, shorter stem, and a steeper seat angle for balanced climbing and confident descending. A slacker head angle improves stability on rougher ground, while maintaining comfort and efficiency for everyday rides or commutes.
Up front, the SR Suntour XCE28 fork provides 100mm of coil-sprung suspension to take the sting out of bumps and roots. It keeps you in control across uneven terrain while maintaining a comfortable ride. The Shimano 2x7-speed drivetrain offers a great range of gears for both climbs and flats, operated by Altus EF500 shifters for crisp, easy shifting.
Braking performance is handled by Shimano BR-M375 mechanical disc brakes, offering dependable stopping power in all weather conditions. Whether you're tackling woodland trails or gravel tracks, they give you predictable control when you need it most.
The 27.5” Merida Comp CC wheels keep things light and lively, while Kenda 2.2” tyres strike a balance between rolling speed and off-road traction. Finishing components from Merida’s Comp range ensure durability and comfort, including a sturdy aluminium seatpost and ergonomic Sport saddle. The frame is dropper-post ready and includes mounts for mudguards and a kickstand, giving you flexibility for all types of riding.
