Abstract:
1. A removable insert device for telescopic fork legs that comprise outer and inner legs and a damping system with a piston and piston rod arrangement arranged within a region defined at least in part by the outer and inner legs, the device comprising: two generally concentric tubes, the two generally concentric tubes being distinct from the outer and inner legs of the telescopic fork legs such that the two generally concentric tubes can be inserted into and removed from within a region defined by the outer and inner legs of the telescopic fork legs, a first medium flow passage defined between the two generally concentric tubes; a second medium flow passage and a third medium flow passage extending in parallel to each other and extending between an upper side of the piston and a lower side of the piston, the second medium flow passage extending between the upper side of the piston and the lower side of the piston via the first medium flow passage, the third medium flow passage extending through the piston between the upper side of the piston and the lower side of the piston, the third medium flow passage being fluidly coupled to the first medium flow passage; a pressurizing member in fluid communication with the second and third medium flow passage; the second medium flow passages comprising at least a first flow control device that is configured to adjust the damping characteristics of the fork legs to different types of terrain.
