Mugen Bulldog sold in 1985 said it has this special air shock. It was preassembled and can't be opened for service. Now I have one to dissect and open up. An interesting coil, o-ring on the piston, seriously nothing more than just a friction damper

係呀師兄。為咗工房眾師兄弟,又為咗科學發展,唯有犠生小小避震

氣壓避震……就係咁簡單

你解答了我心裡30年的疑問!
原來入面咁簡單

好假既氣壓避震,原來裡面"裝彈弓", 真係好有CY feel, 無限:我冇講過我冇裝彈弓

按首頁的縮圖入來以為是無刷摩打心原來是古時的避震

入面當然有空氣而非真空
而活塞活動時亦會有氣體被壓缩
但係同條彈弓彈力/回彈力比較可能同Tamiya無油膠避震効果一樣

多謝師兄解讀多年的問題!我以為連彈弓都冇!謝謝.

又唔係喎,佢真係有吸震效果架,我漏氣果支就同無油油壓一樣跳跳下喇!

按這道理,是否所有無入油的油壓都叫airshock?
