The Fondriest TF2 1.0 frame is at the forefront of structural design. The carbon fiber used is 3K prepreg in a 4x4 twill with a tensile strength of 56 Tons. The carbon chosen provides an excellent level of stiffness while the special design of the Anti Shock seat stays provide a high capacity for absorbing road shock. Other key technical features for the Fondriest TF2 1.0: the Reflex fork combined with the Tapered Head tube provide a high level of torsional stiffness, Integrated cables system allows ideal suspension of the cables with no internal tubes to create additional friction, Integrated seat clamp keeps the shape of the frame but allows height adjustement, monolithic bottom bracket shell has moved the bonding zones to where there is less stress, carbon dropouts with alloy components prevent the quick release from clamping directly onto the carbon frame , 7 sizes available. With the TF2 1.0 Dura Ace, Fondriest combined the TF2 1.0 frame with Shimano Dura-Ace and Mavic SL wheels as these components complimented the design and performance characteristics of the TF2 1.0 frame.
