Carbon Fibre Construction

Strength and durability of our frames are a priority.  That’s why we now use unidirectional carbon fibre (UD) to build all of our frames.

Unidirectional carbon fibre is the perfect material to build bike frames because it is twice as strong and twice as stiff as woven carbon fibre.  This is because the weave of woven fabric crimps the fibres and they are constantly bent in an “S” shape to go over and under each other.  When force is applied to a woven fabric, the fibres try to straighten out which reduces their strength and stiffness. 

UD fibre lays flat and there is no flex when force is applied in a linear direction.  The result of flat, straight, UD fibre is a stronger, stiffer bike.  Also, because UD fibre is twice as stiff and twice as strong, you only need half the amount of material therefore the frames are lighter too.

In a bicycle frame, forces are applied in many directions and combined strength is critical.  While that is clearly understood in frame junctions where fibres are positioned to support the principal stress direction, straight tubes aren't typically considered with fibres being laid linearly.  Tortional rigidity is however heavily impacted along a tube's length, which is the reason why some of the UD fibres on our straight tubes are laid slightly out of line to the principle fibre direction - giving additional support against the twisting moments that hard pedalling and cornering generates.  This is our Linear Asynchronous Fibre Technology (LAF Technology).

Testing

The bikes are assembled to customer specification in our facilities by trained bicycle technicians who are guided and monitored to NVQ Level lll Cytech Trainer and Assessor Standards.

The frames are tested to internationally recognised safety and test standard: Racing bicycles – Safety requirements and test methods – EN 14781:2005 (E).  This European Standard has been developed in response to demand throughout Europe, and the aim has been to ensure that bicycles manufactured in compliance with it will be as safe as is practically possible.

The tests have been designed to ensure the strength and durability of individual parts as well as of the bicycle as a whole, demanding high quality throughout and consideration of safety aspects from the design stage onwards.
