A protagonist in the hi-performance cycling world. The new hi-modulus carbon fibre monocoque frame uses Basso experience in the placement of the direction of the single layers of fibres, creating a main triangle with optimized shaped profiles, which allows a higher resistance to flex and torsion, with as much weight reduction as possible. Astra is a 100% carbon monocoque frame including the bottom bracket and all the bearing housings. The result is a single mould process without the use of different materials.
Cone shaped and edge profiled head tube. The edged shaped rear area of the head tube, which links directly to the two main tubes of the front triangle and in a continuous line to the rear seat stays not only gives the new ASTRA a unique look, but also allows us to maximize rigidity and strength with increased riding precision and great reactivity in the standing position. The larger basis of the head tube creates a wider and more rigid surface, erasing the weaker structural spots. The new BB shell construction procedures, previously only used in our top of the line model DIAMANTE, is now adopted for the ASTRA: the carbon fibre bottom bracket shell made from a single moulding allows us to have a perfect compact structure which gives torsion-free pedalling even at extreme loads, and keep the weight as low as possible. Brand monocoque fork with the 1”-1/8 upper bearing housed directly in the carbon.
ASTRA FRAME TECHNOLOGY
100% 3K Torayca High Modulus Carbon Fiber in T700-MR60
Top Tube: 1 x 0° + 1 x 22° + 2 x 45° = the lightest part of the frame.
Down tube: 2 x 0° + 1 x 22° + 2 x 45° fiber lay-up light and stiff.
HT: 2 x 0° + 4 x 45° the most rigid part of the bike, zero giving in torque.
ST: 1 x 0° + 3 x 22° comfortable and vertical shock absorption.
CS and ST: 1 x 0°, 3 x 22° + 1 x 45° light and stiff.
3K inside tube lay-up of ht - bb and st increases torque resistence.
