For the last several months, I have been bashing the new 2010 Marzocchi 55 RC3 Titanium through the wringer, and the titanium coil fork, with its shiny Nickel coated stanchions, has the legendary Zocchi buttery feel, and the fantastic linearity of a coil, and the apply named Bomber certainly fits the bill.
Marzocchi 55 RC3 Titanium
The 55 RC3 Ti has 160mm of travel, and uses their open bath RC3 cartridge damper, which offers excellent lubrication, cooling and damping properties, and uses slotted bushings for improved oil ﬂow. The RC3 which resides on the right leg, has an MDU bottom out bumper for those big hits, and it has adjustments for rebound, air preload, and hi and low speed compression. The custom wound titanium spring, uses a high quality titanium, and has an adjustment for coil preload. The internally butted 35mm Nickel coated alloy stanchions, connect into beefy lower legs with a stout arch, in a nice speckled titanium gray color scheme. Their new QR20 system, works and feels like a normal thread on QR lever, but still offers the rigidity, strength and security of a bolt on axle.
For the entire testing period, I used the 55 RC3 Ti on my new loyal steed, the All Mountain Yeti ASR 7. It was hooked up to a Sun Ringlé Charger Pro front wheel, and the fantastic Continental 2.4 Rubber Queens tires. The Colorado terrain is predominantly rocky conditions, with many sections of long steep downhills, rock gardens, and ugly loose gravel.
I have to admit that I had never ridden a coil fork before the 55 RC3 Ti, and I was pretty amazed how wonderful it felt. It only took a short distance in a rock garden to appreciate the characteristics of a coil fork. The smooth linearity of the coil is something to perceive, and words like buttery and plush exemplify what is felt. Plenty of forks have nice small bump compliance, but the portion from small-medium through medium-large bumps, in which we spend a great deal of our riding time, seem to be haphazardly handled by most forks. The 55 RC3 Ti just acted exactly the same throughout that lengthy mid travel stroke section, and never had any sudden changes in its characteristics, it was always smooth as silk. When the big hits came the fork ramped up pretty quickly, and though it took the sucker punches without a whimper nor any harshness, I wasn’t able to extract the last vestiges of travel. I am beginning to think that the amount of usable travel of a fork is around 80-85% of it specification?
