So I've been using a Carradice for the last 7 years but on Monday the frame for it broke so today I dragged out my old Bike One backpack. It's still a great pack even though it's now well over 15 years old. There are pros and cons with it. The weight is now on my bike which makes the bike lighter but me heavier. It's easier to find stuff in the backpack as there are more pockets. I also feel my laptop is a bit more secure as it's inside in a pocket against my back rather than hanging over the back wheel
