guy at bike addiction in sydneys northern beaches does conversions from 20mm to 15mm set you back roughly $100 (my last hub was $90)
put it this way, marzocchi used to be heaps heavier then any other fork, but also heaps stronger and plusher, then they went shit for a few years (i only owned one set of marzocchi in that time and they died in less then two months of minimal use) apperently they have picked up there game again but i think most people are pretty skeptical now, the new stuff does look like it will be good, if you went marzocchi dont get anything below a dj2, the dj3s and dirt jams are CRAP. go with whatever looks good haha, i really like the look of (most) marzocchi forks over rockshox, but fox is where its at for me nowdays. lighter, stronger? and just all around amazinger then everything else.
rob, i fail to see how you felt flex in your forks... compared to what? ridgeds? fox40s? any flex you felt would have been from your frame.
Fox is where it's @ in the $$ department as well rabatt...
