Merida Big.Nine / Big.Seven Hardtail MTB | Bombproof Trail-Ready Performance
Backed by over 50 years of manufacturing expertise, Merida's latest generation of aluminium hardtails is built to deliver bombproof reliability and pure off-road fun. Whether you are hitting local singletrack or looking for a rugged, everyday commuter, this bike is engineered to follow modern mountain bike trends, combining a longer reach with a shorter stem for sharp, responsive handling.
At its core is a sophisticated, updated TFS aluminium frame featuring a steeper seat angle for efficient climbing and a slacker head angle for confident, trail-ready stability on descents. Built with massive tyre clearance for up to 2.4" tyres, the frame includes premium details like full internal cable routing for a clean look, inboard disc brake mounts to maximise stopping power, and a tapered headtube ready for future fork upgrades. It is even dropper-post ready for when you are ready to tackle more technical trails.
Up front, a 100mm SR Suntour suspension fork smooths out rough terrain, rocks, and roots with ease.
Powering your trail sessions is a dependable 2 x 7 Shimano drivetrain, complete with matching Shimano hubs, cassette, and chainset for ultra-reliable shifting. When it is time to slow things down, Shimano mechanical disc brakes provide consistent, weather-proof stopping power. Rolling on fast-rolling wheels wrapped in high-traction Kenda tyres, the bike is size-tuned to match your riding style. Choose the 29" Big.Nine wheelset for ultimate rolling efficiency and outright speed, or the 27.5" (650b) Big.Seven wheelset for nimble agility and sharper handling.
