Bicycle suspension which they use for their "FSR Suspension". Several manufacturer had licensed the design from Specialized. Some European manufacturers, such as Cube and Scott, do use the same suspension design, but couldn't import it to the United States until 2013 due to patent protection. Norco, Canadian bicycle manufacturer also licensed the design from Specialized but further optimized the FSR system, calling their own system Advanced Ride Technology (ART). Although not necessarily sharing any general suspension characteristics, these designs all share a certain structural benefit. Because the connecting links are so short, the floating link comes in the form of a rigid
Bicycle and motorcycle geometry axis intersects the ground. The measurement is considered "positive" if the front wheel ground contact point is behind (towards the rear of the bike) the steering axis intersection with the ground. Most bikes have positive trail, though a few, such as the two-mass-skate bicycle and the Python Lowracer have negative trail. Trail is often cited as an important determinant of bicycle handling characteristics, and is sometimes listed in bicycle manufacturers' geometry data, although Wilson and Papodopoulos argue that mechanical trail may be a more important and informative variable, although they both describe very nearly the same thing. Trail is a
