In that class it seems like quite a few riders do a summer trip and spend the rest of the year looking for a new bike to do the next big trip. Partly I guess because they are all so similar and the tech moves on each year plus you want the bike in great shape so you don't need to worry about mechanicals. You can also get a bit tired of any idiosyncrasies if you've spent 3 weeks in the saddle.
