I commuted on my bike in the Portland area for quite some time. The rain-gear kept me dry (except my feet as I lacked anything for my shoes. Always brought a dry pair of socks). And the bike never minded the rain, even though it was often left outside during the day. I wouldn't do that with a really nice bike (more because of the likelihood of theft than rain), but there is nothing wrong with letting your bike get a bit wet.
