Speedplay Pedal Thread

But you can't by just Speedplay springs. They insist you replace the whole overpriced cleat.

The cleats are "throw-away" items and designed to be light and inexpensive--- to manufacture. The C-clip spring is, I agree, underdimensioned but even with a beefier clip I'm not sure that they'd not last longer but be heavier and that would cost them customers--- since a large part of their success was based on weight .

If you are constantly breaking the clips I'd look to using other cleat lubricants. I'd also check cleat position, resp. alignment, since a pinch of misalignment with a dash of pedal body wear and some grinding can increase c-clip wear.
