Locca - Progressive Rear Shock Spring - Olle/R16V

Optimise your trials bike's rear suspension response with the premium Locca Progressive Rear Shock Spring. Engineered for maximum efficiency and superior control, this variable-K spring is developed to transform your rear-end behaviour across a wide range of leading trials machinery equipped with R16V or Olle shock absorbers. Suitable for riders up to 90kg in weight.

By introducing a progressive rate, this spring eliminates the compromises of standard linear springs:

• Optimised Support & Stance (K 7.2 to 8.8): The first few millimetres of travel offer a higher initial rate, guaranteeing greater support and a more stable, precise bike setup right from the get-go.
• Intelligent Progression: The spring stiffness increases progressively through the stroke. This allows for a smoother transition onto the bump stop and exceptional support to absorb heavy impacts and clear large steps.
• Maximum Efficiency: Tailored for trials riders who require the ultimate balance between initial small-bump traction and maximum bottoming resistance.
