fork

[cyril]

Are 1999 Marzzochi supposed to flex under pedal pressure
my disc rubes on my pads when under pressure?
It is a jrT.

is it air or coil? do you adjust it? if it's coil, try changing the oil - check their website for recommendatins. if it's air, make sure you have enough.

also check to make sure none of your seals are leaking

MtnBikerChk is right. Check all that.

Either way forks flex as there will always be uneven load from the rider. That is why Action Tec invented their forks that only the center section moves. Cannondale also does the same design.

Either way check the oil/spring/air and the seals for leaks.
