Perhaps lag behind on jeep, arriving at bend (5)
I believe the answer is:
crimp
'bend' is the definition.
('crimp' can be a synonym of 'bend')
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for crimp that I've seen before include "Fold or press into ridges" , "wave" , "Compress into small folds or ridges" , "tight lock" , "Bend into shape" .)
