The BMC Fourstroke FS03 XT 29er 2013 Mountain Bike is designed to inspire confidence. BMC really believe in the potential of 29er wheels and they carried their Big Wheel Concept through the whole Fourstroke range. The FS03 is the full aluminium version and inherits the suspension and geometry of its brothers, as well as this amazing capability which makes all Fourstroke great all-rounders. Featuring RockShox Reba Forks, a Shimano SLX/XT drivetrain and Shimano SLX hydraulic disc brakes.
The skeleton concept iSC (integrated Skeleton Concept) has been around since the first legendary promachine. Since then, the concept has spent over a decade being refined and redefined. The idea is saving weight by supporting the top tube at the seat tube and increasing the stiffness where it is needed. In the front triangle of the frame. With the help of the latest in FEM (Finite Elements Method) computer technology, we can tailor each tube junction perfectly to the distribution of forces.
