I have found the Simplex Delrin derailleurs to be very durable and shift well. I have had many UO-8's with many miles though the years, left outside through many summers & winters, snow, rain... & the derailleurs are still working! not bad for a cheap plastic derailleur to last over 25 years with all that abuse :-)
