Engineered Compliance

Introducing D-Fuse Technology

D-Fuse components work together as a system to absorb shocks and vibrations, improving performance and comfort on rough roads, gravel or dirt.



D-Fuse was first introduced as a seatpost for TCX cyclocross bikes in 2014. It was created to absorb shocks and vibrations, giving cyclocross racers a smoother ride and more control on variable terrain. The heart of the design is a distinctive tube shape with a round front and flattened rear section. Following its success in cyclocross, including multiple world championship titles, D-Fuse was expanded to the front half of the bicycle. Now key Giant bikes, including Defy endurance road bikes and Revolt X-road bikes, feature D-Fuse seatposts and handlebars. The handlebars work together with the seatpost to add compliance at two key contact points without the unwanted complexity or weight associated with pivots or inserts. There are currently several D-Fuse handlebar options, including the composite Contact SLR D-Fuse and aluminum Contact SL D-Fuse models, plus the gravel-ready Contact XR D-Fuse bar featured on Revolt X-road bikes.
