The stirrup arch is made of aluminum, while the opening arm is made of a special polyamide material. The footboard is also made of polyamide and the tread is made of stainless steel. The “AluPro” model, in principle, provides the same function as the Arena “HiFlex”, but is based on different materials.

MAIN FEATURES

• Unique tension-activated lock and release mechanism located between the bottom end of the outboard pivot footboard arm and the foot support plate/step

• Easy and reliable "one-click" re-engagement of the footboard locking and release mechanism once activated.

SPRING SPECIAL EFFECT

• Due to its design and construction based on flexible polymers, the stirrup transmits a less rigid and much more comfortable sensation to the rider than with conventional products.
• The elastic stirrup arch and foot support assembly are able to effectively absorb and compensate for sudden and short-term impacts exerted by the rider's weight from above, for example during posting, jumping or piracy.
• Considerable benefits for the cyclist: strong relief of the soles of the feet, ankles, knees and hips
• Therefore, also very interesting for cyclists who suffer from orthopedic problems.
