I got about 4k on 020s (rear) gone onto maxxis but not worn out yet due to weather, seem to grip ok and a lot cheaper £185 instead of £250 a pair, so if I get 4k out of them I'll be happy.
update august 3rd, done over 5,000 miles now, the rear is ready for changing but can't complain about the handling, better than the 020s
