Merida Big Nine Xt III1 bike 2025

Modern cross-country race tracks are more demanding than ever which is why we've made the latest BIG.NINE XT more capable than ever too. The lightweight CF3 carbon frame has clearance for 2.4" tyres paired with progressive geometry and AGILOMETER sizing, giving extra comfort and control while maintaining the blistering uphill speed racers need. The Fox 32 SC Performance fork with optimised arch design for increased stiffness to weight ratio delivers 100 mm of tautly controlled travel with a bar-mounted lock, while Shimano's benchmark 12-speed XT drivetrain gives unerringly precise shifts.
Mountain biking is one of the most varied cycling disciplines and probably the most demanding when it comes to equipment. While full suspension bikes offer amazing riding characteristics, the classic hardtail remains one of the purest tools for the job. Our 29er wheel equipped BIG.NINE range comes in carbon and aluminium and features multiple geometry options. The updated CF carbon and LITE aluminium framed BIG.NINE offer truly modern geometry with increased standover clearance and handling stability to better deal with the tough race tracks of today, with downcountry ready TR options that boost fork travel and add in aggressive tyres and dropper posts. The more relaxed geometry of the BIG.NINE TFS and SPEED offers a more comfortable, upright riding position. Our classic hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we could gain in over half a century of bike production and manufacturing. The BIG.NINE range represents the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan' symbolises.

Technologies

X-Taper headtube

Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

Internal Cable Routing

On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

DI2 Ready

Shimano's Di2 electronic shifting system offers fast, smooth and reliable shifting. In particular, in the road world, it has proven itself as the primary choice when top performance is at the top of the agenda. With that in mind, we have a broad selection of performance road frames that are Di2 READY and can accommodate the electrical cable, battery and other little tweaks that the system requires.

Nano Matrix Carbon

NANO MATRIX CARBON is a special kind of carbon fibre where we add extremely tiny, nano-scale particles to the resin that binds the individual carbon fibres together. These then work on a molecular level to protect them from damage. It’s so effective that it can actually increase the finished carbon fibre’s impact resistance by up to 40%, allowing us to build stronger and lighter composite frames that result in a faster and tougher bike.

AWS

This is a method we use to manufacture our carbon fibre frames. First, the carbon fibre that makes up the frame is laid around special formers. We then use a bladder to compress the layers against the outside of the frame mould, giving a smooth and wrinkle-free internal finish, removing any voids in between the layers of carbon that can cause potential weak points, resulting in a stronger, lighter frame.

Wire Port

MERIDA designed headsets that enable all control cables from the handlebar to enter the frame through the headset cover, creating a clean and uncluttered look, allowing for a lighter, stronger and more aerodynamic frame structure than with conventional cable ports. Depending on the model, the cables are run completely internally (including the bar and stem) or semi-integrated, where the cables enter the frame underneath the stem.
