On my most recent trip, bike and geared weighed circa 19kgs not including water (3 litre hydration bladder in the frame pack). If I had an extra £700+ to spend, I probably could have shed another kilo, maybe 2 by getting a lighter weight tent (1.2kgs) and probably a few other bits. If I took my bivvy as opposed to tent, I would have saved another 500 grams. But I wanted the luxury of my tent.
