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

RACELITE 61 ALUMINIUM

We use a minimum of 6061 grade aluminium on all our bikes. It’s particularly well suited to being shaped with our hydroforming and technoforming processes, which allow us to vary the wall thickness to create double-butted tubing and complex frame shapes. It’s also an alloy that welds easily, and once it has been carefully heat treated to maximise strength, it means we can create strong and lightweight bicycle frames for you to enjoy.

TFS - TECHNO FORMING SYSTEM

Manipulating the tube shape and thickness greatly impacts the appearance, weight and functionality of our aluminium frames. One technology that allows us to do that is TECHNO FORMING, where plain aluminium tubes get mechanically formed by using an external form and an internal metal core. The result, beautifully shaped tubes with varying wall thickness, ready to be used to create our technoformed aluminium frames.

F-MOUNT

Being able to turn your bike into an all-weather commuter that has mudguards and other fittings can be a real plus, in particular when riding on wet and perhaps muddy roads and tracks on a regular basis. To make fitting easy, some of our bikes are F-MOUNT equipped. These integrated fittings mounts make adding mudguards fast and simple. Please note that some bikes require model-specific mudguards.

K-MOUNT

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

C-MOUNT

Similar to our F-MOUNT, where various fixing points for mudguards are part of the frame offering, the C-MOUNT equipped bikes have the fixing points for a rear rack already integrated, making fitting fast, simple and reliable. The C-MOUNTS are an additional feature that improves the day-to-day versatility by adding loading capacity to your bike, ideal for commuting and shopping trips. Please note that some bikes require model-specific rear racks.
