    HIGHLIGHTS

    6061 series double butted and technoformed aluminium.

    Dependent on frame size we offer 650B or 29er versions on our TFS and SPEED frame level. The requirements of smaller riders (reduced standover height, preferred lower cockpit) are best met by 650B on S and M frame sizes whilst at the other side of the spectrum, L and XL only come with 29er wheels. Size M is available in either 650B or 29er. 

    Following in the footsteps of the TFS frame which was introduced in 2018, the SPEED frame is now in line to get a makeover for 2019. The introduction of slim tube shapes creates a new look and a more relaxed geometry, through a shorter top tube and a higher head tube, resulting in a more upright riding position and enhanced trail visibility. The new frame also comes with IS brake mounts that are positioned within the rear triangle as well as with kickstand and fender mounts.

    All models down to the BIG.NINE LITE frame level feature a 30.9 mm seat post, the enhanced connection area increases the strength around the top tube/seat tube join and allows the option of fitting a dropper seat post. Models down to BIG.NINE LIMITED allow internal cable routing for the dropper post while the remaining models would require external routing.

    Our classic hardtails are not just a much-loved trail companion but the international cycling press also value our design and engineering work. De Telegraaf in the Netherlands made the BIG.NINE XT-EDITION their test winner and polish bike magazine bikeBoard rewarded the BIG.NINE 500 with their over-all test winning credentials as well as with the ‘lightest’ and ‘value for money’ accolades.

    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.

    Our carbon and LITE aluminium models feature a long 422 mm reach, steep 73.5° seat angle, slack 70° head angle and an 80 mm stem (BIG.NINE – M), affording the BIG.NINE next-generation XC geometry. Aggressive agility meets stable calmness; perfect for today’s demanding courses.

    Technologies

    IMAGE

    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.

    IMAGE

    TFS - TECHNO FORMING SYSTEM

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

    IMAGE

    F-MOUNT

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

    IMAGE

    K-MOUNT

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

    C-MOUNT

    ‘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.
