Every day I commute on my cannonade caad9 and carry a crumpler bag with my 15" MacBook pro, some work documents and often a change of clothes if it's a hot or rainy day.
After years of doing this I'm thinking it's time I started thinking about my back and am considering panniers for the commute. Yes a caad9 is a road bike and not so much a commuter, I also do road riding and prefer using the 1 bike for everything.
Ideally it would be a pannier that could be very easily removed and be able to sustain the weight and clearance.
Does anyone have suggestions on good kit to get for this?
