donc c'est bien ça ! Foes fabrication
This page will give you some background on Brent Foes, the president of Foes Fabrications, and sole designer and driving force responsible for bringing the F-1 forks into production. It concludes with a brief explanation of the adjustments allowed by the design. The following page will give you a solid base as to what is offered by the overall design and internal components of the F-1 Forks.
Brent has been involved with fabricating in one way or another since the early 70’s and has been designing and building suspension systems since 1979. He started out racing motorcycles just out of high school. He witnessed the changes in suspension technology through the years that enabled the motorcycle racers of the day to go faster and faster. After a couple of serious accidents on the race circuit, Brent retired from motorcycle racing and moved on to off-road race trucks. He built (from the ground up) winning race trucks for the Dodge and Nissan teams and rode to victory in the right seat with Roger Means in races such as the Baja 500, Baja 1000, Mint 400, and Pike’s Peak Hill Climb. During this time he was designing and modifying many of the shock absorbers used on the trucks.
Brent started tinkering around with bicycles in 1992. He read up on the blossoming trend of suspension and rear travel and noticed that it was increasing in very small increments, in much the same way it had developed on motorcycles in the 70’s. Taking it to its logical extreme, in 1993 he designed his first suspension bike and came up with the now well recognised Foes Long Travel System with 6 inches of rear travel. At the time, it was considered a flash in the pan concept. However, in its first year of competition, Todd Snider rode it to victory in the Junior National Championships at Big Bear. Last year Robert Naughton rode it to victory in the ESPN Extreme Games at Mt. Snow and the Foes/Yokohama Team was the only team in the nation to finish the National Championship Series with two riders in the top fifteen.
The next logical step was to develop a front fork system that would help to balance out the suspension offered by the Foes Long Travel System. The result is the Foes F-1 Downhill Fork. Eighteen months of design changes, fine tuning, and testing in the San Gabriel Mountains have produced another big step forward in bicycle suspension. The three stage coil springs give it a progressive spring rate. By intermixing the individual springs, the rider can change the overall spring rate to fit his weight needs or track conditions. Additionally, the air and oil along with the springs gives it a wider range of adjust ability. With the option of adding air to the spring chamber, the overall spring rate will increase.
The forks are being manufactured in conjunction with L.A. Gauge, an aerospace firm in Burbank, Calif.
