Removed gear with no thread left (8)
I believe the answer is:
stripped
'removed' is the definition.
(stripping is a kind of removing)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for stripped that I've seen before include "Removed paint - or clothes" , "behaved 'naughtily' in club?" , "Undressed" , "Removed clothing, perhaps forpay" , "having no gear" .)
