At the top of the RockShox Argyle line for 2007 is the 409, a burly air sprung 100mm travel fork. Besides the sweet “Punish-Mint” color scheme, the 409 features useful technology to keep you flowing the dirt jumps, street, and park.
SRAM calls the air spring system “Solo Air”, and it has two main advantages over traditional coil springs:
-The stiffness of the fork is adjustable to suit rider weight and preferences using only a shock pump. This means no buying extra spring sets or messy disassembly to get the correct setup. By adding air into a single valve, it fills both the positive and negative chambers.
-The fork is light! At 2381g (5.25lbs) the 409 is about 191 grams (0.42 pounds) lighter than the coil sprung 318 Argyle, and about 239g (0.53lbs) than a 2007 Marzocchi DJ1.
Damping for the 409 is handled by SRAM’s Motion Control system. Both rebound and compression are externally adjustable, a rare feature on products aimed at this market segment. The floodgate is also adjustable with a hex key. However, the rebound knob can be popped off to reveal the correct size key, and used to adjust the floodgate when you’re out riding. This is an example of the intelligent design prevalent in the 409.
Compression & Floodgate Adjustment
Even though the 409 is light, it’s designed to handle the rigors of day-to-day riding with a forged 6061 aluminum crown, 32mm diameter 4130 steel uppers, and magnesium lowers.
In the axle area, all Argyles feature the Maxle QR. This 20mm axle requires no tools for disassembly, and once the lever is snugged down it can be rotated to a convenient position to avoid damage. You won’t have to worry about getting snagged on the upholstery in the back of your friend’s cars, or skewering any small animals that may cross you path!

In summary, the Argyle 409 is light, stiff, and strong product with features to allow tuning for performance. In the next several months, I plan to give the Argyle 409 a proper whipping on the jumps and out on the trails, with a more detailed review to follow.
