An entry-level triple chainring 29er aluminium hardtail with a more upright and comfortable riding position than our more race-oriented hardtails. The riding position reduces stress on the lower back and improves visibility of the trail or road ahead. A 100 mm SR Suntour suspension fork and Tektro hydraulic disc brakes further enhance comfort and control.

Mountain biking is one of the most varied cycling disciplines and probably the most demanding when it comes to equipment. While full suspension bikes offer amazing riding characteristics, the classic hardtail remains one of the purest tools for the job. Our 29er wheel equipped BIG.NINE range comes in carbon and aluminium and features multiple geometry options. The updated CF carbon and LITE aluminium framed BIG.NINE offer truly modern geometry with increased standover clearance and handling stability to better deal with the tough race tracks of today, with downcountry ready TR options that boost fork travel and add in aggressive tyres and dropper posts. The more relaxed geometry of the BIG.NINE TFS and SPEED offers a more comfortable, upright riding position. Our classic hardtails are the backbone of our range and showcase the enormous wealth of experience and knowledge we could gain in over half a century of bike production and manufacturing. The BIG.NINE range represents the symbiosis between modern frame technology, attention to detail and craftsmanship 'Made in Taiwan' symbolises.

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.
