    long fork and warrenty

    Why does the longer travel forks void the Ellsworth warrenty? What am I missing, it seems a longer for should put less loads on the frame by allowing more drops to be absorbed.

    Thanks for any info.

    Hi,
    Using a longer fork than recommended will decrease the head tube angle and generate a longer lever arm between the front wheel and the frame and this will increase the bending moment and increasing the stress in the frame. Think of the extreme example of a Chopper motorcycle
    A triple clamp fork (Downhill/freeride) will increase the stress in the frame even more since it is very stiff. The stiff fork will transfer most of the loads to the weaker frame. A normal single crown fork will share the stresses with the frame instead.

    Best regards
