MIDRACER INSPIRED DESIGN



CHALLENGE CNC STEM SYSTEM

The base of the System is a block which clamps to the top of the fork shaft, to fi t all of Challenge´s forks. Attaching to this with a smooth, play-free pivot system is the riser, which is CNC machined in a single piece. This is a highly stressed part and welds might compromise its strength.



CHALLENGE CHAIN IDLER

Challenge´s new idlers are made of injection-moulded carbon, and just like carbon in graphite form, the material has its own self-lubricating anti-friction properties built in. The idlers run on sealed bearings which can slide easily along their axles, allowing the idlers to adapt to the chain position as you change gear, minimising side loads. This reduces noise and friction even further.



CHALLENGE FRONT IDLER

Challenge front idlers also slides along there axles to adapt the ideal chainline.
The rings are made from a soft material as Your legs are moving close along this idler.



CHALLENGE REAR SUSPENSION

Placing the central shock absorber below the frame retains the beautiful Challenge lines. The pass through link to the ultra rigid seat spine and properly placed swing arm pivot delivers a plush ride while maintaining excellent power delivery.
