I recently purchased the titanium speedplay zeroes. I love the pedals, but I just noticed on the box that there is a suggested weight limit of 185 (I know, I probably should have seen that before, but the LBS installed them when I was getting some other stuff done). I weigh exactly 185, so I'm not particularly worried--just curious. Does anybody know the reason for the restriction? I assume it is concern for flex rather than breaking strength, given the properties of Titanium?
