I'm with this guy...you all are killing me with your spare tires and multi-tools for 50-100 mile rides. Really?
I believe in preventative maintenance so no multi-tool or chain tool for me.
1 tube, pump, tire lever, I.D. in the pockets and 10 bucks and patches under the shoe insert. 100 mile rides call for a pack of Figs in the spare pocket.
And no cell phone, most of my riding is in the mountains so no service anyway.
