CATEGORY HIGHLIGHTS

Our classic hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we were able to gain in 48 years of bike production and manufacturing. The BIG.NINE and BIG.SEVEN range symbolises the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan'.

Following in the footsteps of BIG.NINE/SEVEN TFS frame which was introduced in 2018, the SPEED frame also received a makeover for the 2019 season. 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.

6061 series double butted and technoformed aluminium. Redesigner in 2019 using a new tube set with a more modern design. Comes equipped with inboard disc mounts, as well as F, C and K-mounts. 

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. 

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.

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.

Technology

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).

IMAGE

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.
