Lightness above anything else. Every gram influences the progress of any race. Its clear to us in Orbea and so we are offering you an ultra-light frame that is within reach of all mountain bike lovers. The material that we have produced this Scape frame is a Scandium Aluminium. It is an alloy known for a few enviable properties, including a resistance to fatigue and high modular elasticity which are responsible for its stiffness. Each tube has been triconically space adjusted to the needs and specifications of each zone. This along with reinforcing the headset, the dropots lightened and the CNC seat stay bridge, finish off a high level frame prepared for any challenges that you might want to present it with.
