I've been using M520 and now M540 SPDs on my commuting / training road bike and find that they dont seem to last long.
They get slopey / creaky.
Do the pedal frames / platforms wear out, or is it likely to be the bearings need a grease and the cleats (which admitedly I dont change often)? Are there any wear indicators on them?
Are there any recommendations for a robust pair of SPDs that will live up to heavy use in all weathers (on the road)? Or do my M540's just need some love?
