No matter the season or weather it's always a nice ride into work but today was not so nice... I had a blow-out, first one in years. So I flip the bike upside down and remove the rear wheel, get ready to pull one side of the tire off the rim when I see that a 4" section of the tire casing tore away from the bead wire. I enjoyed taking my bike out for a walk for the last 1.6 miles (with an ankle sprain no less).
