Concept

Efficiency
The suspension (based on our APS system) and geometry were optimized for all day comfort without compromising efficiency. The top tube and cockpit provide enough breathing space, while a low bottom bracket and relaxed angles improve the handling. On the APS suspension specifically developed for the speedfox, we have increased sensitivity and responsiveness at the same time, resulting in a smoother and more reactive ride under pedalling.

Lightweight
Built with triple butted, hydroformed aluminum tubing, the speedfox is the lightest full suspension frame in its class. The frame design is simple and efficient with a matching component specification, making the complete bike both a versatile package and a great value.

iSC

integrated skeleton concept

BMC has defined its brand name through technical advances.

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

advanced pivot system

Unsurpassed power transmission, traction control, and comfort.

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

Remarkably simple sag adjustment.

Just set the sag adjustment according to the indicator, and go. Trailside adjustments have never been simpler.

Triple butted tube set

Triple-butted tube set made of a 6000 alloy. Triple-butted means that the tube has three different wall thicknesses.
