In 2003, the TCR frame was offered in carbon fibre construction and marketed as the TCR Composite range. In 2006, Giant added a higher-grade carbon fibre frame marketed as the TCR Advanced frame, which was characterised by an integrated seatpost (ISP). These frames were most notably raced at the Tour de France by T-Mobile's professional team. Using this design, the seatpost on the new frame must be cut precisely to fit the owner by a trained Giant dealer. The TCR Advanced SL frames with ISP continued to be raced internationally, most notably by the Rabobank team (2009-2013), Team Giant-Shimano (2014), Giant-Alpecin (2015–2016) and Team Sunweb (2017-2018).
