Barely have trouble replacing lead from wire obtained with ease (9)
I believe the answer is:
available
'wire obtained with ease' is the definition.
I can't tell whether this defines the answer.
'barely have trouble replacing lead' is the wordplay.
'barely' says to take the centre (the word is bare of its external letters).
'trouble' becomes 'ail' (synonyms).
'replacing lead' becomes 'able' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The middle of 'have' is 'av'.
'av'+'ail'+'able'='AVAILABLE'
'from' is the link.
Can you help me to learn more?
(Other definitions for available that I've seen before include "Not otherwise committed" , "To hand" , "Ready or able to be used" , "Can be had or obtained, in stock" , "Unoccupied" .)
