Marzocchi have always been advocates of the open bath system as it has many advantages over a closed damper, in fact I would go as far to say that the only negative this design has is ultimately its biggest positive. Since suspension forks need to rapidly telescope, moving up and down thousands of times a ride, bushings should be coated in a bath of oil allowing friction free movement. The only deign that truly accomplishes stiction-less performance is Marzocchi’s proven "Open Bath" technology.
Since oil completely bathes the internal bushings, seals and cartridges all the moving parts glide smoothly; this eliminates friction that causes forks to feel harsh and unresponsive.
Because of the larger oil volume it takes longer for the oil to get dirty, which in turn reduces seal and bushing wear. The higher oil volume keeps temperatures under control. Closed cartridges (a rear shocks for example) work very hard in confined spaces which creates friction which in turn causes heat therefore this heat causes damping fade, so a higher volume of oil will give a more consistent level of performance over extended runs.
Lastly the performance remains at a consistently higher level for longer. With low oil/ closed systems the performance drop can be huge if the fork isn’t correctly maintained. This can also contribute to worn stanchions as the fork dries out
Under new American ownership since 2010, Marzocchi has gone back to its roots with reliable open bath oil damping technology. Simpler controls, lighter weights and a 3 Year Warranty (with no servicing restrictions) make this the original Fit & Forget fork. If you're tired of being made to service your forks every 6-12 months then switch to a Marzocchi and spend more time riding your bike! Marzocchi have been making Motorcycle forks for 60 years and MTB forks for 20 years. So they are confident in their open-bath-oil-technology internals and high quality seals. Marzocchi offer a fork for every type of riding and a range of weight saving and innovative new features – including Shimano’s new QR15 axle standard. Whatever type of riding you do, there’s a Marzocchi fork that fits.
