Merida's heartland has always been bombproof aluminium hardtails and their entry-level 29er is no exception, it uses a sophisticated TFS frame with the latest technology, full internal cable routing, tapered headtube and inboard disc brake mounts.
There's no point making a bombproof frame and then hanging poor components on it. Merida has opted to go for a 2 x set up and retain a focus on using Shimano components wherever possible for longevity and performance.
SMOOTH WELDING
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.
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.
X-TAPER HEADTUBE
Merida's X-Tapered headtube offers the space for a tapered fork to be fitted. Tapered forks offer superb stiffness and precise and deliver confidence-inspiring steering.
DOWN TUBE EXIT
Ensures that internally routed cables and wires can’t move freely and remain easily accessible for servicing.
TFS - TECHNO FORMING SYSTEM
Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with internal metalcore.
RACE LITE 61 ALUMINIUM
Merida uses a minimum of 6061 aluminium. The payback is that it’s possible to make lighter and more advanced frames by using additional heat treatment and double-butted wall thicknesses to produce light and stiff frames.
