spring. You adjust the air-spring by
raising or lowering the oil level in the
legs.
By using different combinations of

“Fine-tuning the bike“.

fork is designed to combine the
advantages of comfortable, safe
conventional forks and rigid, light
USD forks. The result is a unique
combination of being rigid, precise in

washers, fig 3, and optional springs
are available to suit different tracks
