After a year of light use, ten races to include two XTERRA, I finally got around to make sure my free hub was alright on my Crossmax SL. Not wanting to search up and down God's green earth for the ideal mineral oil I opted to use plain old baby oil. The free hub was relatively clean, no dirt or grime just grayish black oil that was super easy to cleanup. Now for the questions; What is the minimum amount or play (run out?) in the nylon? (or what ever it is made out of) bushing before replacement is necessary? And why wouldn't Mavic use a lubricant that has more shear strength than mineral oil? Maybe a thicker oil would require stronger springs for the paw and induce more wear and noise? Thoughts?
