Giant D-Fuse Technology | Engineered Compliance

We first introduced our D-Fuse technology in 2014. Initially developed as a seatpost for pro-level cyclocross bikes, it was designed to absorb shocks and vibrations and deliver a smoother ride and more control on variable terrain. The heart of this pioneering concept is its distinctive “D-shaped“ tubing with a round front and flattened rear section. Following its success in cyclocross, including multiple world championship titles, D-Fuse was expanded to endurance road bikes and beyond! Learn more here: ht
