There has always been an aluminium trailfox frame in the BMC lineup, and the latest revision of the series is no exception. BMC kept the weight low and the strength high by using the best quality aluminium tubing and processes. This is not an entry level design; suspension performance and geometry are directly transferred from BMC's benchmark TF01.
isc - integrated skeleton concept
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, BMC can't tailor each tube junction perfectly to the distribution of forces. Cleverly selected skeletal reinforcement elements at the nodal points and the spread of the top tube distribute the impacting forces perfectly and result in BMC's typical crosslock. distribute the impacting forces perfectly.
aps - advanced pivot system
The ideal suspension system converts all of a rider's energy into forward propulsion, while at the same time absorbing impacts. Mechanically, these two goals are at odds with one another. But BMC's APS rear suspension satisfies these two goals by carefully calculating the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock.
How is this accomplished? With APS the virtual pivot point is positioned so that constant chain tension is maintained for forward acceleration. As such, pedaling forces are used for forward propulsion with no loss of energy transfer in the suspension system. At the same time, the shock system ensures optimum rear wheel traction, guaranteeing that those pedaling forces are not only getting to the rear wheel, but to the ground, as well. The end result is a suspension system that provides extreme power transfer efficiency, uncanny traction, and excellent comfort.
initial load indicator
Just set the sag adjustment according to the indicator, and go. Trailside adjustments have never been simpler.
Triple-butted tube set made of a 6000 alloy. Triple-butted means that the tube has three different wall thicknesses.
