Why progressive fork springs from Wirth?

Fork springs sag over the years: the front dives under braking, bottoms out over bumps and feels vague. Wirth springs are progressively wound and firmer than stock. They respond softly early in the stroke and firm up towards the end.

  • less brake dive, no bottoming out
  • better road contact, even with older forks
  • no more air assistance needed in the fork
  • German ABE approval included
  • DIY installation possible, instructions included

Finding the right set

Each set contains two springs matched to specific models – see the “Suitable for” tab in each product. Order fork oil and preload adjusters separately if needed. Can't find your model? Get in touch – as a Wirth dealer we can source further sets directly.
