The 3D System is one such exclusive innovation: this structural adjustment system permits a wide range of handlebar heights for a given frame size without compromising front end stiffness. A higher or lower bar position is easily obtained to suit the rider's physique, fitness level and riding style, all without compromising performance.
The 3D System lets the user choose from three effective head tube lengths for a given frame size for positioning flexibility. These lengths are as follows:
•Basic head tube length, no 3D spacer
•Basic head tube length + 15mm
•Basic head tube length + 25mm
Thanks to 3D,
•handlebar set at a 15mm height retains an extra 5% of rigidity
•handlebar set at 25mm benefits from 11% retained rigidity, compared to such settings obtained with conventional stacked spacers.
Since the 3D System offers three effective head tube lengths, a rider can set the right position initially, but can later revise this position as fitness, taste or riding style evolve over time.
This feature offers optimal positioning, which translates to a safe, comfortable, efficient bike with predictable, responsive handling for an exhilarating ride in all circumstances.
