Learners cycling naked in streets facing each another (8)
I believe the answer is:
students
'learners' is the definition.
(student is a kind of learner)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for students that I've seen before include "Sent dust to the learners?" , "Sent dust to those who learn" , "Learners or scholars" , "Pupils at school, university etc" , "Pupils or scholars" .)
