As you will see in my post on my commuting setup, I am a pannier bag man.
I often see commuters with rucksacks and I wonder why.
As I see it, here are the pros to a rucksack:
no rack required, so road bikers tend to use them as their silly bikes don’t have racks
no expensive pannier bag required; any old rucksack will do
total kit weight is lighter
no wobble weight on the bike; the bike is kept light
easier to carry than 99% of pannier bags
wobble is on my back
back gets even more sweaty, this is the overriding factor that sways it for me
more weight on my arms and bum
shoulder / back ache
Those who know my commuting setup will know that weight is less of a concern for me, I rather focus on carrying everything I could possibly need and being as comfortable as possible. The rucksack is, to summarise, uncomfortable for me, but I’d love to know your thoughts too.
