Contact Local Shop

Our heartland has always been bombproof aluminium hardtails. Half a century of frame building experience counts for a lot.

We've made a few changes to the UK range, upgrading the Big Nine and Big Seven 15 to use the sophisticated TFS frame and creating the UK Exclusive Big Nine and Big Seven 80 featuring a RockShox branded fork and Shimano Deore 1 x 12.

All Big Seven and Big Nine frames feature:

- full internal cable routing, for a clean, neat set up
- tapered headtube offering the potential for future upgrade
- inboard disc brake mounts to protect the brake and maximise stopping power

Reliability is enhanced by the inclusion of as much Shimano componentry as possible.

There are a wide range of sizes; Big Nine for taller riders, Big Seven for shorter riders with a healthy overlap of sizes in between.

For riders in the middle, riding style can be taken into account. If you are looking for speed and efficiency, choose a Big Nine, if you are looking for agility choose a Big Seven.

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.

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.
