Kaipaith said:Some supermarket stuff however is just too bulky to fit into panniers without being stripped down - and then when it is stripped down would leave too little room for much else. I'm talking things like cat food, other tinned foods, loo rolls, kitchen rolls that kind of stuff. Too much for panniers - but a trailer would be ideal.
Stuff and nonsense! My fiancée and I do our weekly supermarket shop with panniers (and a rucksack in case of overflow) without difficulty. All you need are decent sized panniers and good packing skills! And as for bulk packs of loo-roll, a bungee-cord will have that bad-boy riding high on the top of the rear pannier in no time! Safe as houses. We've done this both with a tandem and with two bikes/two sets of panniers. Tandem works better, and is more fun up the hills!
