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

Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

SMOOTH WELDING

This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

INTERNAL CABLE ROUTING

On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

DOWN TUBE EXIT

DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

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.
