如果想不用呔水, 可不可以用比較軟的綿呔? 如果正常setting 是頭尾32呔, 頭尾都落呔水, 為什麼不用頭尾30, 或25呔而不落呔水? 其實呔水真正幫呔做什麼? (What is the real effect of tire traction compound on foam tires?)
those "Tire water" stuff are quite amazing. I think it literally metls the surface giving it some grip. There is some kind of chemical reaction to the foam tires. It made alot of difference....1/12 and tire water go together.
