The 2025 Merida Big Seven 20 is an entry-level aluminium hardtail mountain bike, ideal for riders seeking a balance between comfort, control, and off-road capability. With 27.5-inch wheels, it offers a more agile and nimble ride compared to its 29er sibling, the Big Nine. Built with Merida's half-century of frame-building experience, the Big Seven 20 delivers a reliable, versatile bike for both newcomers and seasoned riders.
Key Features:
Aluminium Frame & Comfort-Focused Geometry:
- The Big Seven TFS IV aluminium frame offers a lighter, yet durable structure, designed with modern frame technology and slim tube shapes for a more relaxed look.
- The comfort-oriented geometry includes a shorter top tube and a higher head tube, resulting in a more upright riding position. This improves both comfort and trail visibility, making it easier to handle for longer rides.
27.5-Inch Wheels:
- The 27.5-inch wheels are perfect for riders seeking more agility and a nimble ride. Compared to the Big Nine’s 29-inch wheels, the Big Seven is quicker to accelerate and more responsive on tighter trails, making it a great choice for smaller riders or those who prioritize maneuverability.
SR Suntour 100 mm Travel Suspension Fork:
- Equipped with a Suntour XCT30 HLO suspension fork offering 100 mm of travel, the Big Seven 20 provides enough cushion to absorb bumps and rough terrains, giving riders greater control and comfort over uneven surfaces. The fork also includes a lockout function, ideal for climbing or riding on smooth paths where suspension is less necessary.
Shimano 8-Speed Drivetrain with Double Chainring:
- The Shimano 8-speed drivetrain with a double chainring setup (32 teeth crankset) ensures versatility and plenty of gearing options for various terrains. Whether climbing steep hills or speeding down a trail, this drivetrain offers smooth and reliable gear shifts for efficient riding.
- The Shimano CS-HG400-8 cassette and KMC Z8.3 chain ensure durability and consistency in performance.
Hydraulic Disc Brakes:
- The Shimano MT200 hydraulic disc brakes provide powerful and controlled stopping power in all weather conditions, increasing rider confidence and safety.
- With Shimano RT10 rotors, braking performance remains consistent even on challenging trails or during extended descents.
Internal Cable Routing & Sleek Design:
- The frame features internal cable routing, keeping the cables neatly tucked inside the frame for a cleaner aesthetic and reduced maintenance.
- This design also protects the cables from external elements like mud and debris, increasing the bike’s overall durability and reducing wear and tear.
Sizing & Fit:
- The Big Seven 20 is available in sizes XS, S, M, catering primarily to smaller and medium-sized riders. Its frame geometry, combined with the 27.5-inch wheels, provides a perfect fit for riders who value agility and a more responsive ride.
Additional Components:
- The bike includes MERIDA CC rims and Shimano TX505 hubs, paired with MERIDA K1080 tyres, which offer excellent traction and stability on various surfaces.
- The MERIDA Sport comfort saddle and MERIDA CC seat post further enhance rider comfort during long rides, while the VP VPE-891 pedals complete the bike’s essential components.
