Merida Big.Nine 29er Hardtail MTB | Your True Trail Journey Begins
Take the definitive step into "proper" mountain biking. Backed by over 50 years of manufacturing expertise, this premium 29er aluminium hardtail is engineered to unleash your off-road potential.
Following modern trail trends, it features a longer reach paired with a shorter stem to give you razor-sharp responsiveness, a steeper seat angle for efficient climbing, and a slacker head angle that delivers total confidence when pointing down steep singletrack.
At its core is a sophisticated, updated TFS aluminium frame that strikes the ultimate balance between rugged trail capability and everyday usability. Packed with high-end features, it offers full internal cable routing for a clean silhouette, inboard disc brake mounts that protect the caliper while maximizing stopping power, and a tapered headtube ready for future upgrades. It even comes dropper-post ready for when you are ready to tackle technical terrain.
Up front, the trail-tuned 120mm X-Fusion Migo air suspension fork with beefy 32mm stanchions and a hydraulic lockout smooths out heavy impacts, roots, and rock gardens with progressive efficiency.
Powering your progression is a modern, simplified Shimano 1 x 9 drivetrain that eliminates the front derailleur for smooth, reliable shifting, zero chain drop, and less clutter on the bars. For unmatched safety and stopping power, Shimano MT200 hydraulic disc brakes offer effortless, one-finger stopping power in mud, rain, or dust. Rolling on fast, efficient 29" wheels built with dependable Shimano hubs and high-traction Kenda tyres, this machine is size-tuned to maximize rolling speed and outright efficiency on every trail session.
