All in all, I have been very happy with the gear I took with me to cycle across Europe.
Before I left on the trip, the total weight of everything I had in panniers was in the 15 kg range. After the first couple of days, I barely noticed that my bike had any weight on it so this range seems to be acceptable for someone like me. I have created a gear list for people doing something similar who are looking for a checklist of sorts. Below it you will find my comments on some of the gear and what little I would change now that I have hindsight. I will post a separate review on my GPS in the coming couple of days.
