im not sure whether it is becoming a habit or not, but it is usaully when i sit in position, it feels locked and when i put it back into the normal position, it clicks.
I dont really use clips for mountain biking, due to the type I do (downhill).
Could it be my ankle is straining form bad landings and crashes i have had in the recent past becuase i have crashed alot? (i didnt seem to hurt my ankle at the crashes)

p.s i ride a norco atomik
