carrying large items on a bike

[clayt74]

Yep def the rucksack,  I've had to pack to go away for work n had a 55ltr rucksack loaded with steel toecap boots, overalls and enough clothes n wash bag for a week weighed in at 20kg!! No probs as weight is on seat make sure shoulder straps are pulled tight once seated onthe bike and mine also had a waist band that I could pull tight...... It was rock solid and barely effected the geometry of the bike..... Only down side was high winds..... Me + rucksack made for a very good sail
