fork is one of the most popular options for racers and downhill weight weenies alike. Their top of the line DH fork not only weighs in at a very competitive 5.9 lbs thanks to its air spring, but it also offers a host of effective adjustments that will allow pretty much anyone and everyone to dial the fork in to their liking. But like a lot high end suspension, too many riders don't take the time to learn what each adjustment does and how to use them, which is a shame because this fork is so adaptable to the terrain and riding style. Being air sprung not only means that it will be lighter than its coil sprung brothers, the BoXXer R2C2 and R2, but also benefits from an infinitely adjustable spring rate. Just a touch too soft? Add in a few pounds of air, as opposed to having to install a new coil spring that may be too big of a jump. The fork also uses its adjustable DropStop to control hard bottoming at the end of the stroke. Damping adjustments include separate high and low speed compression, as well as both beginning and ending stroke rebound. Confused? No need to be! Watch the video below to better understand how to tune and get the most out of your BoXXer World Cup fork.
on the RockShox website.
The RockShox website features a great setup guide that should be mandatory reading, even if you think you know what you're doing. You'll find spring rate and damping suggestions, as well as a tutorial on setting up the sag on your fork.
Pictured above are the adjustment knobs of a 2010 fork. Although the 2011 gets updated with easier to turn dials, you'll still find them in the same place. Compression adjustments, both low speed and high speed, are made at the top of the right fork leg. Beginning and ending stroke rebound dials are located at the bottom. You now no longer have any excuses for not taking the time to properly setup your fork!
The 2011 BoXXer World Cup may look the same from the outside, but there has been some major tweaking done to the internals for 2011. Things have been simplified on the spring side of things, with a new Solo Air assembly that not only controls both the positive and negative air chambers, but uses a more reliable air valve in place of the previous year's O-ring design. The damping leg also sees some changes for '11, starting off with new and easier to manage knobs on the outside, as well as changes to the rebound damping components that RockShox says will do a better job of keeping it and compression duties separate. This has allowed their suspension engineers to re-shim the compression piston and allow for a wider and more effective tuning range.
Now that you have a good idea of when to turn each dial and what it will do, it's time to start experimenting. As always, the first step is to find a suitable spring rate and make damping adjustments from there. Like I suggested in the previous week's Tech Tuesday, to get a better idea of what each adjustment does, it helps to find a section of trail that you are familiar with and ride it twice, once with the one adjustment backed mostly out and once with it turned mostly in. Repeat this process with each adjustment individually and you'll soon have a clear understanding of what is happening. Don't be afraid to try a setting that you may not usually use, you could end up surprised at the results.
