ONE-FORTY 400

When creating high-end aluminium frames, we use our proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

To get the most out of an aluminium tube in terms of shape or varying wall thickness, we apply various forms of manipulation. The most complex but also the most effective is hydroforming, where an aluminium tube is inserted into a negative mould, and a hot emulsion of water and oil is forced through at pressure. The end result is a perfectly shaped aluminium tube that enables us to create beautifully crafted and lightweight aluminium frames.

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.

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.

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.

This system means you only need a single tool to tighten important bolts, making it easy to secure them while out on the trail and also making routine maintenance faster and simpler. The bolts have a specially shaped head on one end that fits into a matching recess in the frame, preventing rotation. That means there is no hardware bonded into the frame itself, so damaged threads or bolts can be easily replaced.

A suspension design where the traditional pivot point on the seat stay is eliminated in favour of a flexstay design. This uses the compliance of the material and specific shaping of the tubes to allow for the seat and chain stays to move apart as the suspension moves through the travel. By removing this pivot point at the seat and chain stay junction, we save weight, reduce maintenance needs and add stiffness to the frame structure.

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.

Rear suspension kinematic that uses a flexstay design to minimise weight and maintenance needs. Each frame size has a specific progression rate, with longer reach models having increased progression to better suit harder and/or heavier riders. An adjustable flip chip can be used to run full 29er or mixed-size wheels while preserving the geometry for consistent handling. Flexstay-Adjustable-Size-Tuned kinematic: FAST, because it is.

Mounting points for an optional extra-long fender to boost protection over the standard short fender. The full-length fender reduces the amount of dirt and water spray from the rear wheel, keeping the rider cleaner and drier and also extending the life of bearings and cables. The bolt-on mounting points mean the fender is fixed rigidly, so there is less noise, and the paint finish of the bike is not damaged.
