LOOK innovation on this frame model: the carbon is combined with natural linen fibres to filter vibrations from the road and so increase comfort on the bike. The composition of the 765 is mainly carbon because this material provides lightness, strength and general rigidity for the bicycle. A layer of linen fibre has been positioned between the carbon thicknesses on the fork and chain stays to encourage the dissipation of vibrations. Another thickness of linen fibre placed around the tube inside the fork and chainstays provides better elongation properties for these tubes, again to filter micro shocks and vibrations that fatigue the cyclist. The inclusion of linen, with its vibration filtering properties, increases the bicycle’s general performance: the cyclist’s body being less loaded, all his energy will be concentrated on steering and pedalling. A real benefit for very long, tough outings.
The 765 has Endurance geometry with a shorter, higher cockpit than on a Race geometry bike (for example the 795). The cyclist has a less stretched out position and so is more comfortable for long distances.
Major design work has been done on the rear triangle to improve comfort and performance. The chain stays are asymmetric: the right chain stay is oversized compared to the left to balance forces due to transmission of the pedalling force. They are short and rigid to guarantee a dynamic bike. Still with a view to improving comfort the seat stays have been extended and are slimmer to improve comfort.
The new 765 includes all the brake and derailleur cables in the tubes, and the cable housing end stops are removable. It is thus possible to change them to assemble the frame with a mechanical or Di2 groupset.
The 765 bottom bracket is to the Press Fit 30 standard. Integration of the bearings into the frame offers several advantages: longer bearing life, increased stiffness for better force transmission, and finally ease of fitting and removal.
