Hmm,
I thought ideally you need about 15mm of travel left?

theres about 10mm of bump stop you can't fully compress ( wel i can't anyway )

how much sag you got with you on bike keefy?

Have to say the bike handles good and soaks up the bumps ok,...I was just a little shocked how much travel I was using.

30mm is about the sag "norm" i run mine at about 35mm as i prefer a softer fork on bumpy roads, i've got preload to wind in if i need it for track plus I can use a bit more compression damping.
