Photo of the day: Gears
When you look at modern bicycles...if you look at modern bicycles...they've evolved ages since the days of the old Penny Farthing. They are engineering marvels. All those gears and spokes. All the shifting and aerodynamics.
I don't have a bike, though I wish I did. Not a fancy racing bike, just a little something to ride in the sunshine. But I liked the symmetry of this shot.
