The basic aim of anti-dive is to separate braking from suspension so one does not adversely effect the other.

The technique is to use the rotational force created at the point of braking (disc brake) and transfer that into a pivot (leading link on fork) so that under braking the tendency for the for to dive is balance by the braking (mechanical link).

The trick is to achieve this in a way that does not simply stiffen or lock out the suspension but rather, still leaves the suspension fully active.

The result is a front suspension that has all the travel available to do the job intended (soak up the bumps) and not be lost to brake dive.

The ride is a better, safer and more controlled one. We call the product S.U.B. (Stability Under Braking) anti-dive.

The spin off's are a front end that has an effective travel greater than the travel actually afforded in the product, so a long travel fork (effectively 100-120mm) without the associated difficulties of altered frame geometry etc. from such a fork.
