If there were evidence bigger gears may cause injury, the group that should find it (the papers) is the one now pulling that restriction.
USA Cycling has not stated any risk associated with gears.

I am making a sweeping general statement.
There is no study showing equal power output using a bigger gear is more damaging than using a smaller gear. I can't prove the negative there is no study. I can state I have searched for this for years and argued that there is no evidence of injury with USA Cycling
I cannot find anything by USA Cycling stating that.
I would like to be proved wrong on this as I have been looking for over a decade, but you can't prove a negative.
