Product Description

BMC: Speedfox 03 Trailcrew NX - 2017

The Speedfox Trailcrew highlights the playful side of BMC and the mountain bike culture within. With 150mm of plush travel from BMC's legacy APS suspension system, paired with wider bars, wider rims, and wider tires, things are bound to get rowdy. Its super short chainstays, long toptube and a downright awesome, long front-center…this bike was made to put a smile on your face.

APS – Advanced Pivot System

A well-designed full suspension bike offers the control and confidence to ride a trail without hesitation. Ideal suspension systems maximize pedaling efficiency without compromising the ability to soak up the bumps. BMC's solution is the Advanced Pivot System (APS) which optimizes kinematics and pivot placements, leverage ratios, axle paths and shock dimensions. Iterative calculations fine-tune all the suspension properties of each of our distinctive full-suspension models to achieve the best ride characteristics for any terrain. The result is a light, stiff and compact structure that promotes excellent control and energy transfer for the rider.

When accelerating, an inertial force is generated which attempts to compress the shock system. BMC's APS solution counteracts this effect. It carefully calculates the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock, instead, the chain tension compensates for this effect. As a result, all the pedal power is used for propulsion without any loss of energy through the suspension. The shock system ensures optimum traction, and therefore ensures that power is transferred to the ground.

BMC's solution to finding the optimal pivot placement, APS achieves this through iterative calculations in order to fine-tune such suspension characteristics as leverage ratio, axle path, and the amount of kickback. The unified rear triangle is linked to the main frame by two short links, with the upper link actuating the shock. The result is a light, stiff and compact structure. Impacts are absorbed by the shock system, providing excellent comfort for the rider. Another example of BMC's forward-thinking cycling solutions from the Impec R&D Lab and the efforts we go to put the rider in the middle of the equation, the advanced pivot system offers the rider the perfect combination of efficiency, traction, and comfort.
  • Traction - To achieve just the right amount of travel for each of BMC's distinct models they optimized the leverage ratio, ensuring the optimal balance between progression and small bump sensitivity.
  • Control - Low suspension ratio means greater oil flow and energy dissipation. Pick your line and let the bike do the rest. 
  • EfficiencyThere is a lot to be said for keeping the rubber side down. With less time in the air you cover ground faster.

Longer, Slacker, Lower… 

BMC's 29er Big Wheel Concept (BWC) combines a long top tube, slack head tube angle and a wide bar paired with short stem and chainstays. For 650b wheels we dug deeper. We went longer, slacker, wider, shorter and a bit lower. The effect? A more aggressive and more playful ride. The Speedfox Trailcrew family excels when the trail points downhill - with a plush APS set-up and an awesome, long front-center. This bike was born to rip.


BMC believe that off-road bikes are deserving of the classic ‘showpiece’ designation that bike lovers admire. Their engineers worked magic by making the Speedfox Trailcrew one of the cleanest-looking frame platforms thanks to an integrated chain guide, hidden ISCG mounts and full internal cable management for up to 5 cables. A sick trail bike for those who also appreciate attention to aesthetic detail. 


BMC is a performance-oriented company. They take pride in making products that win races. For their full-suspension mountain bikes, this usually comes from a pedal-focused APS design. But the Speedfox Trailcrew has brought forth a new attitude. For ripping up descents and letting it all hang out, bombing single tracks, or getting the rubber off the ground the Speedfox Trailcrew APS set-up is plush and playful...something different, something awesome.
