Pretty much all my bikes have been used for touring and for commuting. The one I commute on most often is a Trek 4500 mountain bike that went from British Columbia to tip of South America as well as other places. The aluminum frame cracked near the right chainstay. I had it welded in Bariloche and it held up for the last part of that trip. However, given the repaired frame, it has now been retired from active touring and so only used for commuting now.
My other bikes I still use for both commuting and touring. I haven't owned a car since 2001, so fun to switch between different bikes to get groceries, go to work or go on a tour...
