I have 6 way with 230 mm and I change spring now from 222 manitou , spring is shorter(ti spring) my qustion is , can I ride with shorter spring or what can happen? . 230 and 222 have the same storke size but springs are diffrent .
As long as the 222 is long enough for the preload ring to contact it properly, everything will be fine. Measure from the end of the spring to the end of the threads on the shock body. If its >8mm, you're all set.
