The Big Trail has been a hit with the mountain bike press and trail riders alike. Bikeboard.cc confirmed that we 'nailed it', while MBR, IMB and many more confirmed that the Big Trail is firmly at the top of the trail hardtail game.

Conversations between UK bike shops and our German R&D team resulted in the development of a fun-packed and hugely capable bike. Trail bike geometry combined with a long travel 140 mm fork and grippy 2.4" wide 29er trail tyres make this the perfect companion for exciting trail sessions and demanding all-day rides over rough terrain. It's perfectly suited to UK riding.


The modern trail bike geometry has a slack enduro inspired 65.5° head angle, steep seat angle and a long reach. A short seat tube delivers a low standover height giving plenty of space to manoeuvre on the bike when the trail gets technical but still accommodates a long travel dropper post. The geometry means most sizes work for most body sizes so riding style can be factored in. If you want to go crazy fast, take the longer size, for agility, take a shorter size.

The Big Trail has hidden talents, in addition to two sets of bottle bosses, there's a trail mount under the top tube that allows you to carry tools and extra gear on the bike. It's also possible to fit mudguards and a rack if you want to trek further afield.

X-TAPER HEADTUBE

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.

SMOOTH WELDING

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.

INTERNAL CABLE ROUTING

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.

INTERNAL CABLE ROUTING
IMAGE

DOWN TUBE EXIT

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

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.

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.

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.
