Merida BIG.TRAIL 400 – Big Travel, Bigger Thrills. The Ultimate Hardtail for Real Trails.
Take on the most technical trails, steep descents, and flowing singletrack with confidence aboard the Merida BIG.TRAIL 400 — a high-performance hardtail engineered for trail enthusiasts seeking full-suspension fun without the complexity or cost. With a modern slack geometry, 29" wheels, a long-travel 140 mm fork, and a dropper post as standard, this bike delivers downhill capability, climbing agility, and pure riding pleasure in a simple, durable package.
Trail Geometry Meets Hardtail Efficiency
The BIG.TRAIL 400 shares the same proven frame DNA as its higher-end siblings, built from advanced TFS aluminium with trail-specific geometry. A slack head angle, long reach, and short chainstays give this bike exceptional control on descents and playful handling in corners — all while preserving the low-maintenance benefits and direct power transfer of a hardtail.
140mm of Front Travel – Plush, Confident Handling
Up front, the SR Suntour XCR34 LOR fork with 140 mm travel smooths out rooty trails, rock gardens, and big hits. The fork's robust 34 mm stanchions and lockout function deliver stiffness for aggressive riding, while also allowing efficiency on climbs or rolling terrain.
1x10 Shimano Drivetrain with Shadow+ Stability
Equipped with a Shimano Deore M5120 rear derailleur and Deore M4100 10-speed cassette, the BIG.TRAIL 400 offers smooth, reliable shifting and plenty of range for steep climbs and fast descents. The Shadow+ clutch mechanism stabilizes the chain over rough terrain, reducing drops and drivetrain slap for a quieter, more controlled ride.
Confident Braking & Premium Cockpit
Braking duties are handled by Tektro M275 hydraulic disc brakes, paired with Shimano RT10 rotors for precise and consistent stopping power in any condition. Up top, the MERIDA EXPERT CC handlebar and MERIDA COMP EC grips deliver all-day trail comfort and control, while the MERIDA COMP TR dropper post adds serious trail capability — allowing you to adjust your saddle height on the fly for climbing or descending.
Big-Wheel Grip & Flow
Roll over anything with confidence on 29" Kenda Regolith tires mounted to MERIDA COMP TR rims and Shimano MT400-B hubs. The 2.4" tread width offers outstanding traction, support, and speed, while black stainless spokes and thru-axle compatibility ensure long-term strength and durability.
