I don't bother carrying spare chainlinks but not having a spare tube or basic repair kit is a bit silly... and you can buy a decent mini-pump for the price of 4 days' travel cards.
I do have a mini-pump as it's attached to my frame. I also have a set of Allen keys and a screw driver. Tubes are a bit bulkier so I don't bother any more. Since I got better tyres I've not had any punctures.
