For the first time Giant has applied ONS to the standard TCR, whereas previously the tubes were round. Based on last season?s TCR Advanced, its only downgrade is to the carbon-fibre.
Talking of the T700, the TCR Composite has been updated too. These changes make the frame 20 per cent lighter and 20 per cent stiffer than the same frame made from T700 carbon. Combined with the new META composite fork, the front end has less flex in line with the frame. These areas are the stiffest points in the tube and carry much of theĬompression or extension loading for the tubes.īy moving these widest points further apart, the head tube is better triangulated and therefore stiffer. Both top and down tubes are broadly triangular in cross-section (albeit with rounded corners), with the widest parts at the top of the top tube and the bottom of the down tube. ONS (Off-set Neutral Surface) is a complex principle that is put to good use at the front end of the Giant TCR. This allows the frame to be baked at a higher temperature, making it stronger. A first for Giant, it contains nano-particles, which in effect means carbon has been ground up and added to the resin, much like a hi-tech aggregate. Added to the carbon and of equal importance is the resin, which is used for holding the carbon sheets together. T800 was used last season and will continue to be used for much of the frame, but a few high-stress areas have been upgraded with T1000 carbon. At the heart of the frame, the carbon matrix has been altered.
