Gears slipping under pressure. Did a quick google search and that says it's probably cable tension, but I've pulled it tight enough so it can't be that, can it? Anything else it could be? It's really annoying. Indexing is just about OK (though not perfect), I've pre-stretched the cable. And it works fine if I'm just pootling, but any big increase in pressure on the pedal and it crunches.
