Personally, I live in cooler climate, so I need to dry biking things or else they are still damp next day. I just make sure I use the coolest setting possible. I gentle wash (setting) clothes in cold water. I am fairly new (one year) so I'm not sure about longevity of clothes but so far they seem to be holding up well. There have been prior good threads on this topic:

If possible, I would line dry over dryer.
