Shoddy quality of disorganised ski ascent (9)
I believe the answer is:
tackiness
'shoddy quality' is the definition.
'disorganised ski ascent' is the wordplay.
'disorganised' is an anagram indicator.
'ski'+'ascent'='skiascent'
'skiascent' is an anagram of 'TACKINESS'.
'of' acts as a link.
(Other definitions for tackiness that I've seen before include "sleaze" , "Vulgarity" , "Shabby, still-wet, condition" .)
