|talk about a wide range of sizes in the pro peloton. Is Sevilla that small or is Millar just a freekin giant??|

|Some of those guys are itsey, bitsey, tiny dudes. Every see them standing next to the podium girls? The winner stands on a box, and the girls are still taller.
Time trialists like Millar tend to be bigger.

|Theres some serious perspective going on there. Look at the front and back wheels on each bike- the back wheels are almost 15% smaller. Also, the water bottles should be the same size, if perspective isn't a factor. Seeing as the lead rider's water bottle is about 1/3 longer in the photo, I'd guess he isn't much taller than the guy following him.
Motion can also play tricks on some cameras, because cammera shutters have various shapes and move across the film as objects are moving across the picture plane. In this case it looks like the sutter was a horizontal slit that moved from top to bottom, because the front of the wheel is farther back than the bottom, evidence that the top of the picture was exposed a fractional second before the bottom. In this case it would not affect relative sizes, but it can make the actual perspective harder to judge.

|Look more closely at the wheels on millar's bike and then sevilla's bike - they're the same. Millar is closer to the camera, which probably used a wide anle lens. this is what causes the distortion. A slower shutter speed would cause image slurring, which is not evident here. Millar is 6'4" i think and Sevilla is 5'7". big difference. However, notice how small size of the bike Millar is riding. Looks like it could be a 55".|

|You are absolutely correct sir. The photographer used a wide angle lense, probably a 28mm, and that is exactly what caused the said distortion.
Camera shutters have nothing to do with perspective distortion.

|As they are in this case.|

|When I said "there's some serious perspective going on", I meant exactly what you said- that the view was based on a wide angle shot. Telephoto lenses result in shallower perpective, wide angle ones in deeper perspective.
And in the picture, the wheels are NOT the same. Not only is Millar closer to the camear, his front wheel is closer to the camera, so it appears much bigger. They are all 4 700c wheels, which is exactly why I pointed that out as evidence of strong perpective. DUH.

|the front rider could be ridig 27" front, 700c rear, while the rear rider could be riding 650c front, 24" rear.
And little guys dont need as much water as the big guys. Why carry all the extra weight of a full-sized bottle when a mini-bottle will do?
