I have just fitted some new 2009 Reba team maxle forks which come with the pushloc lock-out, but the problem is they don’t lockout the same as my older Reba forks. Is this normal??

Didn’t know whether the lockout is removed and they have a different type of damping system

check oil levels in the compression circuit.
If there’s not enough oil in the upper right leg (and it needs to be spot on) then the lock out wont work.

here on the website and follow the instructions:
