I'm not sure how many others out there carry a few basic tools in the hope of getting the out of trouble should the need arise, but I do. I carry: Tyre pressure gauge Shifter Pliers Screwdrivers Plastic tie straps Tie wire "single shot" wd40 blob Torch Electrical tape I plan on adding some tyre plugs and a mini compressor to my kit. At this stage all the gear fits under the seat of my Sprint GT. The tie wire assisted another rider in a group ride I took part in a month or so ago when we had to jury rig a fix for a failed hose clamp to keep him mobile. In my opinion a good maintenance program is invaluable, but there are times when things just go wrong. Thats life. So what do you carry for road spares? Obviously off road needs are different... Anything you've found particularly useful? And I don't mean roadside assistance membership - I've got that too as extra insurance.
