Will you miss the 10mm? Depends on the kind of riding you do… Yes/No/Maybe I'm afraid! Sorry I can't be any more specific, but too much depends on the setup. Mav's are VERY active forks, Rev's still very active but not quite so if you get me. You might notice that more than the travel…
Will you miss the lockdown to 100mm? Again, yes/no/maybe. Do you use it much? I barely use it on my Mav's, so wouldn't miss it, but I suspect if you do use it you might miss it as lowering the front by 50mm for climbing is quite a difference.
