Abstract

Disclosed is a front fork damper installed in a bicycle front fork formed of a fork pipe, a bottom case coupled and axially movable relative to the bottom case, and a hydraulic fluid filled in between the bottom case and the fork pipe. The front fork damper is joined to the bottom end of the fork pipe to buffer movement of the bottom case relative to the fork pipe in such a manner that the hydraulic fluid passes upwards through the front fork damper rapidly at a high flow rate, and passes downwards through the front fork damper slowly at a low flow rate.
