Bump threshold is adjusted with the blue knob located on the bottom of the right fork leg. "彈跳臨界點"是可以經由前叉右腿下方的藍色旋鈕來調整的.
This gives the rider the ability to adjust the force required to cause the BrassMass valve to open, depending on the bump input from the trail. 它讓車主可以依照林道中彈跳的狀況, 調整打開BrassMass閥門的力道 (P.S : 這個BrassMass valve關起來時, 前叉等於鎖死狀態, 打開時才能壓縮/伸展)
Turn the knob clockwise to make it harder for the BrassMass valve to open (higher bump threshold), counterclockwise to make it easier for the BrassMass valve to open (lower bump threshold). 將旋鈕順時針轉動, 會提高BrassMass valve開啟的臨界點, 反時針轉動會使BrassMass valve開啟的臨界點降低. (P.S 簡單的說, 順時針轉動時, 前輪回彈力道要更大才會讓閥門打開, 讓前叉可以壓縮)
There are 22 clicks of adjustment. The factory setting is full out (counterclockwise), then 6 clicks in (clockwise). 共有22小格可以調整. 原廠設定值是全開(反時針轉到底)後再順時針轉六小格.
