40 Float 27.5 203 RC2 FIT Fork - 2015

In the age of 27.5 inch wheeled downhill bikes, the 2015 FOX 40 Float 27.5 RC2 FIT fork has already won World Cups, and it’s not done yet. Built with a longer dropout offset and larger tire clearance to accommodate for a larger wheel, this is a truly elite suspension product that can be fully appreciated by the mere mortals among us as well. If you’re looking to build the bicycle equivalent of an off-the-shelf F1 car, this is a really good place to start.

If you've ridden coil-sprung forks, you've most likely found yourself in between spring rates. By this, we mean that you're either using excessive damping to compensate for a spring rate that's too soft, or getting jack hammered by an over-sprung fork in order to keep your front end riding high in the travel. With an air spring, that's no longer an issue. Instead of your suspension setup being limited by available spring rates, you're able to select the precise spring rate that matches your weight and riding style. Better yet, there's an easily adjustable bulkhead under the spring side fork cap which enables you to adjust the volume of the air spring in just a couple of minutes. This means that you're able to maximize the air volume for a linear feel that's almost indistinguishable from a coil spring. This feature also means that you're able to reduce the air volume for a more progressive ramp-up in the bottom of the stroke. Additionally, the large volume of the air spring means that the Float spring utilizes extremely low pressure, between 45 and 80 PSI, which minimizes both friction and wear on the system.

The 40 FLOAT’s stanchions and internal sliding components are treated with a refined Kashima coat, which further reduces friction as compared to the previous Kashima coat. Essentially, the gold outer layer remains the same—what has changed is the base anodizing, which results in an even smoother surface than before. This is in addition to a new, lower-friction lubricating oil, which adds to the dramatically smoother ride. In addition to the friction reducing benefits, Kashima coating is harder than standard stanchion coatings. This equates to a longer wear life, as well as more supple suspension action.

The 40 chassis carries over from the 2014 model year, which we’re thrilled about. This refined, World Championship winning chassis has been scrutinized by FOX’s RAD program to remove any unnecessary weight from the lowers, crowns, and stanchions. A replaceable threaded insert at the brake mount and dropouts makes stripped threads and broken bolts manageable instead of catastrophic. And perhaps the coolest upgrade is a bleed port on the back of each seal on the lowers, which enables you to equalize pressure that's built up in the lowers. Pressure buildup comes from a combination of temperature and altitude changes, and that excess pressure causes friction at the seals. Having the ability to equalize that pressure at the top of a run with just a quick push of a button ensures that your fork is as supple as can be, every time that you drop in.

The FOX 40 Float 27.5 FIT RC2 Fork is compatible with 27.5 inch wheels, a 20x110mm axle, and in the color Black.
