BIG TRAIL 600

Contact Local Shop

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.

HIGHLIGHTS

While clearly a trail loving long-travel hardtail, our new BIG.TRAIL also offers built-in versatility through hidden rack, fender and kick stand mounts in case you like to turn the BIG.TRAIL into a ‘SUV’ commuter. 

Ability to fit two water bottles into the frame without making the bottles difficult to reach. Perfect for long marathon races and extended trail sessions.

Our BIG.TRAIL rolls on 29er wheels and has tyre clearance for up go 2.5" trail tyres. The combination of 29er wheels and 2.5" tyres offer plenty or corner and climbing grip, while the big tyre volume and the 29er 'rolling over ability' give our trail hardtail extra comfort and stability.

The new 'Trail Mount' is positioned underneath the top tube/seat tube junction and these ingenious fixing points makes fitting an additional tool or a pump a breeze. The 'Trail Mount' offers a real advantage if you prefer to keep the weight off your back or if you are heading out for an extra-long outing where you might need to carry additional gear.

We feature internal cable routing on all models. Cables are routed through the frame, entering and exiting through smooth sockets. Only a clever system for our internal guiding and fixing guarantees reliable and rattle free routing, whilst the cables are protected from moisture and dirt and gives the bike a cleaner look.

A long reach, paired with a slack 65.5° head angle and a steep seat angle make our BIG.TRAIL a solid descender even when the trail is littered with roots and rocks, while maintaining impressive climbing abilities, due to the central seating position over the bottom bracket. The extra short seat tube and low stand over hight help to create lots of space to manoeuvre the bike when the trail gets demanding but also allow for long travel dropper posts.

Most models offer Boost technology at the front and rear. The shallower axle standard of 110 mm (front) and 148 mm (rear) allows for a wider spoke angle, resulting in a stiffer and stronger wheel, hugely beneficial on these bikes given the impacts they endure. The Big Trail 400 has 100 mm fork spacing.

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.

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.

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.
