  • Featuring a 100 mm air suspension fork and easy to accelerate, nimble 27.5" wheels, the BIG.SEVEN 100 allows you to cover ground efficiently and in perfect control. The slightly more minimalistic double chainring setup provides a broad range of gears, perfect for long off-road sessions and fast blasts through the urban jungle. The slightly more upright riding position puts less strain on the lower back and also improves the visibility of what lies ahead.

    "The alternative to our BIG.NINE 29er hardtails for riders who prefer the smaller 27.5"" wheels. The latest aluminium frame generation of our BIG.SEVEN TFS and SPEED mountain bikes featuring slim tube shapes create a new look and a more relaxed geometry. A shorter top tube and a higher head tube offering a more upright riding position and enhanced trail visibility. Similarly to our 29er wheeled BIG.NINE range, our classic BIG.SEVEN hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we could gain in almost half a century of bike production and manufacturing. They symbolise the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan'. "

    To reduce production and delivery times, we are sometimes forced to make last-minute specification changes. Please be aware that those changes might not be reflected on these product pages and images.




    Our 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.



    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.



    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.



    Ensures that internally routed cables and wires can’t move freely and remain easily accessible for servicing.



    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.



    Technoforming is a mechanical forming process, shaping the tubes by using negative moulds, at times combined with an internal metal core. 



    ‘F-Mount’ equipped bikes have integrated fittings for mud guards (some bikes require model specific mud guards), making fitting fast and simple.



    Integrated mount on the chainstay to fit a MERIDA kickstand (or any commercial kickstand).



    ‘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.
