Greek character with walking stick bends on track (7)

I believe the answer is:
chicane
'bends on track' is the definition.
'chicane' can be an answer for 'bends' (I've seen this before). I'm not certain of the 'on track' bit.
'greek character with walking stick' is the wordplay.
'greek character' becomes 'chi' (letter of the Greek alphabet).
'with' is a charade indicator (letters next to each other).
'walking stick' becomes 'cane' (cane is a kind of walking stick).
'chi'+'cane'='CHICANE'
Can you help me to learn more?
(Other definitions for chicane that I've seen before include "Sharp double bend in race track" , "This bridge hand might not make one" , "Double bend obstacle on racing track" , "Racetrack obstacle" , "Sharp double bend as obstacle" .)
