Clear; distinct; light - The Chiaro provides the perfect balance of aerodynamics, stiffness with light weight, and is one of the most advanced racing bikes available. The Chiaro is an all round road bike, designed to be faster and more efficient in all conditions.

The frame has highly advanced features, including internal cables, accessed by removable cable ports - no more restricted access to sticky cables causing poor shifting, or loss of cables with no access. 
The main tubes are of a rounded square section providing stiffness but controlled flex.  This provides a comfortable ride aided by extremely thin seat stays allied with a strong chainstay and bottom bracket area.

The high modulus unidirectional carbon fibre frame matched with high-end components make this the perfect road bike, ideal for sportives or the local club ride.

Tests have surprised and delighted all who have ridden the bikes – read the comments in Reviews.  

All of our bikes  are individually custom painted for a perfect deep gloss lacquer finish, which can also be designed to be totally unique, so that you can stand out from your friends and competitors.  

Sizing Method

We determine frame and component sizing to ensure perfect fit by defining your anatomy with 6 body measurements.  We will compute the optimal geometry of your bike for the riding style required using specialized software tools using technology from our partners SizeMyBike.  We can also do this for you, please go to the following link. We will then send you your correct frame sizing.

Two bike fittings are typical: comfort and performance. The seat tube length and the top tube length enable us to select the right frame size.  The saddle height, saddle setback and crank length are tuned to optimise power and efficiency.  Stem height and stem length optimise comfort and aerodynamics.  

Bike Fitting

We also offer a bike fit and cleat fit service that has been extremely successful. We do not use a jig, nor a computer or try to force you on to a bike that is not for you, we work alongside you to find the perfect fit for your cycling to make sure you are safe, comfortable and efficient, whether that be riding to work or racing nationally, everyone has his or her own need.

We take into account the following considerations when setting a position, handling, power application and efficiency, minimising aerodynamic drag and also comfort:

  • Initial discussion of your cycling history, goals and positional problems
  • Adjustment of saddle height and set-back
  • Handlebar and stem position adjustment
  • Brake lever position assessment/adjustment
  • Cleat adjustment
  • Pre and Post adjustment measurements taken

These sessions take around 2 hours and are delivered by British Cycling trained cycle coach and bike fit specialist Jon Bateman who ensures that all Azione riders can get the very best out of their investment, while also putting smiles on faces with his meticulous and caring approach which delivers measurable performance results. 

Carbon Fibre Construction

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


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.
