ive tried marzochi site... but not very helpful here...

my mates bomber 33 TST 2 coil, are VERY hard to compress and he needs to know how to change the preload

the rebound is the black knob on one of the fork legs and the only other knob is the progressive lock out on one leg top... the other leg has a blue bit that can be moved with a spanner and there is a rubber bung with an allen key head inside it

how to do set the preload on these? he aint getting much travel at all and they are rock solid

    seems that the allen head on the top of the left leg is the preload adjuster.

    Make sure that the lock out is also turned off and the adjuster under the cap is adjusted suitably.

    they could have hydro locked, its a common problem with tst2 dampers.....
    zocchi tell you its a new damper, or a factory service, this is a load of poo, its actually a very easy job... if you want ill send you instruc's....
