I bought the Topeak Beam rack and DXP bag and they work great on the bike. Problem is, it's kind of a pain to work with otherwise with my clothes and lunch etc for work (carrying the bag around off the bike). The messenger bag or backpack was better off the bike but a little more uncomfortable on the bike. Has anyone experienced the same thing?? I've though about just bringing my bag on my back with maybe just the clothes in it and then unload the DXP into the backpack for going to work. Anyone do anything similar?
