In Seattle, most flats are caused by pinches, glass, staples, nails, and it’s much worse in the rainy season. Starting last year, I stopped using Mr. Tuffy, and instead roll the best tires with the most rubber and replace them as soon as they wear. I carry two tubes, and a tire boot for sidewall blow outs. I’ve also got fast patches and regular old Rema Tip Tops.
I also believe in flat karma, where some years you’ll flat all the time, and sometimes almost never. To put positive flat energy into the universe, I always ask a fellow cyclist who’s stopped if they need help and will give up a tube to the needy. I even bought a tire during a ride for a friend once.
What hazards await you on your ride and how do you avoid them? What’s your flat karma?
