BMC - trailfox03

Versatile trail bike

There has always been an aluminium trailfox frame in the BMC lineup, and the latest revision of the series is no exception. We keep 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 our 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, we can 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 (advance pivot system)

An ideal suspension system converts all the rider's energy into propulsion while the shock system absorbs the impacts regardless of the effects of acceleration. By carefully calculating the position of the pivotal points on the APS rear suspension, we can achieve this aim with great precision.

When accelerating, an inertial force is generated which attempts to compress the shock system. With APS, the virtual pivotal point is positioned so that the chain tension compensates for this effect. All the pedal power is used for propulsion without any loss of energy in the suspension. The shock system ensures optimum traction and therefore ensures that power is transferred to the ground. The impacts are absorbed by the shock system providing excellent comfort for the rider. The advanced pivot system offers the rider the perfect combination of efficiency, traction and comfort.
