Sometimes [often?] caused by running a "too-tight" chain on the PDS bikes. I did mine recently (in fact I posted about it here too, asking the same question). I've run it several hours since with no issues.

Thanks for the advice, i'll rip the seal out and put a new one in. My chain definitely isn't too tight, but i checked that concave washer and it spins easily so that may be the culprit. Anyhow, i'll replace the lot and have it sorted.
