I must be the minority here riding latex tubes. Why? Boulder CO "flat rides average 1500 feet climbing. Hilly rides 3-5000 feet. House is on a 15% grade hill. I need every extra watt I can get just to keep up with area cyclists.
For tools, small Speedsleev saddle bag carries what's necessary for roadside repairs. Have helped out friends and strangers with spare tube, tire boot, gas cartridge. Guess I've paid it forward for when I was mercifully picked up by a stranger on mountain road, no cell service, and out of spare tubes. To each their own
