In our 45 years of manufacturing bikes we’ve seen plenty of change, fashions have evolved, and different styles of bikes have come and gone. Our core skill remains the same, building high quality, high performance bikes for every kind of rider. We are so confident in our abilities we don’t just put our name on our bikes, we test our products far beyond ISO requirements and offer a Lifetime Frame Warranty.
Our Stuttgart based R&D team is constantly developing the next generation of bikes. With state-of-the-art in-house test labs, extensive workshops and of course many hours of riding, they create, test and refine new frame concepts. Our designers work in close cooperation with our pro athletes who push our products to the very limits in some of the most demanding conditions.
MERIDA’s philosophy is that you should work with industry experts when they can do something better than you. This is definitely true of carbon production. We collaborate with the best producers to ensure we are always at the leading edge of technology. Our partners are constantly developing highly refined production techniques for other industries, meaning that we can select the best manufacturer to satisfy the varying needs of each frame we develop.
CARBON PRODUCTION IS VERY COMPLEX
Marketing has created mystique around carbon frame quality; labels such as high tensile, high modulus, super high modulus and ultra high modulus abound. These terms relate to the carbon’s properties, not its quality. Toho or Torray are sometimes mentioned to add perceived credibility. Some brands say all carbon is the same, or that they use only ultra high modulus fibres. In reality, high performance carbon frames must incorporate many different fibre types, each carefully positioned to achieve the right technical properties. Our SCULTURA frame weighs under 750 g, comprises 400 individual carbon sections, it takes over 45 hours to build.
CARBON IS DEFINITELY NOT ALL THE SAME
Visually identical frames can vary in quality due to the level and mix of carbon fibres used. MERIDA uses a CF number to demonstrate the performance level; 2 is the lowest, 5 the highest. Subtle tweaks to the carbon fibres used both save weight and improve performance.
We have produced cutting edge aluminium frames for many years, continually refining our knowledge and developing new technologies. We take great care in selecting or, in some cases, developing grades of aluminium appropriate to the demands of each bike we manufacture. For example, 6016 aluminium enables super thin wall thicknesses with amazing strength, ideal for demanding off-road riding and racing. 6066 aluminium is extremely light and durable, allowing manipulation to create the best possible stiffness to weight ratio. 6061 is the minimum grade we use, developed for the aerospace industry, enabling the production of lightweight and highly advanced frames. The way aluminium is treated and manipulated is as crucial as the grade selection. There are a number of processes involved:
DOUBLE AND TRIPLE BUTTING
Double butting describes tubes with two wall thicknesses; thicker at the ends and thinner in the middle. Triple butting describes tubes with three different wall thicknesses along their length, optimising strength where it is needed but minimising weight in areas subjected to less stress. All our aluminium is heat treated. Frames are heated to very high temperatures (a T6 temper) then quickly cooled in water or oil to ensure the alloying elements don’t precipitate. Frames are subsequently heated to a lower temperature, artificially ageing and significantly strengthening them.
HYDRO AND TECHNOFORMING
Hydroforming involves the insertion of tubes into negative moulds. A hot emulsion of water and oil is forced through at pressure, enabling them to be formed into complex shapes. Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with a metal internal core. Smooth welding, also known as double pass welding, refers to a second pass over the weld providing a clean organic look to the frame; at first glance you will be convinced it is carbon, not aluminium.
For peace of mind and reassurance, all MERIDA frames come with a lifetime warranty against manufacturing defects. Restricted to the original purchaser of the bike on production of proof of purchase (frames from model year 2015 onwards). *Conditions apply. * The lifespan of a bike is up to ten years. The “intended use” (see instruction manual) has to be noted.
Cables, housings and brake hoses are clamped under tension to prevent rattling when the trail gets rough. All inlets are completely interchangeable to deal with Di2, hydraulic hoses, brake cable and gear cable housings etc.
INTERNAL CABLE ROUTING
Cables are routed through the frame, entering and exiting through smooth sockets. The bike looks neat, whilst the cables are protected from moisture and dirt.
DOWN TUBE EXIT
Ensures that internally routed cables and wires can move freely without causing any trouble whilst remaining easily accessible for servicing.
The seat and chainstay profile and carbon lay-up schedule are adapted to work like a flat leaf spring, absorbing surface bumps and reducing vibrations.
NANO MATRIX CARBON
To protect the integrity of carbon frames, the fibres are bonded together with an epoxy resin with added nano particles, increasing impact resistance by up to 40%.
Carbon forks provide superb vibration damping and precise steering. All road bikes feature a full carbon fork; the steerer and fork blades are all made of carbon.
NACA FASTBACK PROFILE
The aerodynamics are based around a NACA0028 teardrop profile (National Advisory Committee for Aeronautics) which is truncated. Air moves around the tube as though the missing rear section of the teardrop were still there, saving weight by using less material.
AWS – Anti Wrinkle System
When creating the individual carbon elements, an inflatable bladder is used to ensure there are no wrinkles inside the tube as these can add weight and create weakness. This results in a lighter, stiffer and stronger frame.
Using a tapered head tube with 1 1/8" bearings in the top and 1 1/4" or 1 1/2" in the bottom creates superb stiffness and precise, confidence inspiring steering.
Prolite 66 Triple Butted Aluminium
Our proven high-end aluminium (6066) is extremely light and durable. Using triple butted wall thicknesses and hydroforming technology, we can tune the aluminium tubes to give the best possible stiffness to weight ratio.
Superlite 16 Aluminium
Our latest grade of aluminium (6016) enables super thin wall thicknesses whilst delivering amazing strength, ideal for demanding off-road riding and racing.
Racelite 61 Aluminium
We use a minimum of 6061 aluminium. The pay back is that it’s possible to make lighter and more advanced frames. We use an additional heat treatment and double-butted wall thicknesses to produce light and stiff frames.
HYDRO FORMING SYSTEM (HFS)
Tubes are inserted into negative moulds and a hot emulsion of water and oil is forced through at pressure, enabling them to be formed into complex shapes.
Techno Forming System (TFS)
Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with a metal internal core.
Sometimes called ‘double pass welding’, a second pass over the weld gives a clean organic look to the frame. At first glance you will be convinced it is carbon.
A forged aluminium component under the front and rear caliper allowing heat to dissipate through CNC-milled cooling fins. Tests show that temperatures are reduced by around 35% and cooling times are shortened, optimising the performance of the brake.
Post Mount Disc / Chainstay Post Mount Disc
Post mount disc brake calipers fit directly onto the seat stay for a strong and light connection whilst chainstay post mount positions the caliper on the chainstay within the rear triangle for extra protection and better distribution of braking forces. Another benefit is that internal cable routing is also easier and neater via the chainstay.
A single-pivot rear suspension system optimised for XC riding and 1x drivetrains. A super light (80g) carbon rocker and linkage system create a light, efficient rear end, totally eliminating pedal-bob.
Float Link Rear Suspension
The lower shock mount moves with the system to deliver sensitive response characteristics. Our engineers can precisely influence the transmission ratio and progression meaning a ‘Float Link’ rear suspension system appears to offer more travel than the model name suggests.
Bikes/frames with the symbol ‘Di2 Ready’ are prepared for the installation of Di2 technology with battery mounting in the seat post or within the fork steerer.
Selected front forks use a 100 mm wide through axle 12 or 15 mm in diameter to increase lateral stiffness. A 142 mm wide 12 mm rear axle fixed directly into the frame increases rear end stiffness whilst simplifying wheel removal and replacement.
Boost Standard Through Axle
New Boost standard – wider axle widths; 110 mm front and 148 mm rear, allowing a shallower spoke angle for stiffer wheels, especially beneficial in 29ers.
FLIP FLOP HEAD
Aero bikes deliver the best possible aerodynamics, but superb wind-tunnel performance data is useless if the rider can‘t get into the correct position. The ‘Flip Flop’ head allows seat angles to be optimised for comfort.
Designing WorldTour bikes is similar to Formula 1: apparently nondescript details can result in saving split seconds. Integrated seat-post clamping minimises turbulence at the top tube.
Patent pending design. Carbon is good at absorbing vibration but to increase comfort we shape our REACTO, 30.9 mm and 27.2 mm post using our exclusive S-Flex design.
Integrated mount on the chainstay to fit a MERIDA kick stand.
‘F-Mount’ equipped bikes have integrated fittings for mud guards (some bikes require model specific mud guards), making fitting fast and simple.
‘C-Mount’ equipped bikes have the fixing points for a rear rack already integrated (some bikes require model specific rear rack), making fitting fast, simple and reliable.
Lockout / Remote Lockout
The suspension fork and/or rear shock can be locked, either directly or via a ‘remote control’ lever on the handlebar.
Casting Motor Bracket
Sophisticated shape only possible due to casting technology, creating an integrated appearance as well as an extremely strong connection between the e-bike motor and frame for improved performance and reliability.
