Do cyclists have a lower than average incidence of kidney stones?

I honestly do not know. I asked Google, and it didn't know either.

Although I suppose the opposite effect could happen if you try to compensate
for Ca loss by ingesting more and there being some limitation of
absorption...

I suppose. I suspect the question has not been studied. We are left to
speculate. I would imagine that a cyclist who does not attempt to
compensate for calcium lost to sweat would be less likely to get stones,
as there is less calcium around to excrete via urine. OTOH, a sedentary
person who eats excess calcium should be more likely to get stones. Now,
a cyclist who attempts to balance calcium intake to calcium lost to sweat?
I wouldn't expect the frequency of stones to differ from the average joe,
unless the cyclist doesn't hydrate enough (BIG factor for stones
there, in everyone) or unless there is a limitation to dietary absorption.
