With more than 50 years of design and manufacturing experience behind it, bikes like the BIG.NINE 400 create the backbone of our international business. As one of the most popular bikes on our line-up, the 400 features our proven double butted aluminium frame, a 100 mm air suspension fork from Manitou, a super smooth and ultra-reliable Shimano 11-speed drivetrain and powerful yet easy to control hydraulic disc brakes from Shimano. Welcome to the MERIDA family.

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.

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.

SMOOTH WELDING

This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

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.

DOWN TUBE EXIT

DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

RACELITE 61 ALUMINIUM

We use a minimum of 6061 grade aluminium on all our bikes. It’s particularly well suited to being shaped with our hydroforming and technoforming processes, which allow us to vary the wall thickness to create double-butted tubing and complex frame shapes. It’s also an alloy that welds easily, and once it has been carefully heat treated to maximise strength, it means we can create strong and lightweight bicycle frames for you to enjoy.

TFS - TECHNO FORMING SYSTEM

Manipulating the tube shape and thickness greatly impacts the appearance, weight and functionality of our aluminium frames. One technology that allows us to do that is TECHNO FORMING, where plain aluminium tubes get mechanically formed by using an external form and an internal metal core. The result, beautifully shaped tubes with varying wall thickness, ready to be used to create our technoformed aluminium frames.

F-MOUNT

Being able to turn your bike into an all-weather commuter that has mudguards and other fittings can be a real plus, in particular when riding on wet and perhaps muddy roads and tracks on a regular basis. To make fitting easy, some of our bikes are F-MOUNT equipped. These integrated fittings mounts make adding mudguards fast and simple. Please note that some bikes require model-specific mudguards.

K-MOUNT

When using your bike in an urban environment, where you might not always have the option to use a specific bike stand, a kickstand is an ideal solution to park your bike safely. Some of our bikes come with a neatly integrated K-MOUNT, which makes fitting a MERIDA kickstand (or any commercial kickstand) easy. And if you don’t want to have a kickstand and prefer the clean appearance of your frame, the K-MOUNT is neatly tucked away underneath your chainstay, difficult to spot if you don’t know it is there.

C-MOUNT

Similar to our F-MOUNT, where various fixing points for mudguards are part of the frame offering, the C-MOUNT equipped bikes have the fixing points for a rear rack already integrated, making fitting fast, simple and reliable. The C-MOUNTS are an additional feature that improves the day-to-day versatility by adding loading capacity to your bike, ideal for commuting and shopping trips. Please note that some bikes require model-specific rear racks.
