Thanks for the tip! I can't use mirror anymore, too dangerous because I kept looking at my beautiful self instead of looking at the road :roflmao2:

Imagine your right arm is a string pulled taut from handlebar grip to right shoulder. From the grip that string goes rearward and upward. Now imagine you are pivoting your shoulders and torso to the left, as most of us do when looking over our left shoulder. Your right shoulder also moves to the left. Now the string has to go rearward, and upward, and leftward. It can't stretch, so it can't do that - to add the leftward reach, the string has to go less far rearward or less far upward. Dipping your right shoulder reduces the upward reach and lefts the string reach leftward.

11¢ and 12¢ will be rounded down to 10¢ and 16¢ and 17¢ will be rounded down to 15¢. 13¢ and 14¢ will be rounded up to 15¢ and 18¢ and 19¢ will be rounded up to 20¢.

Make sense now?

So is 20¢ rounded down to 10¢ or rounded up to 30¢?

nooo it's rounded to the nearest nickel. 1 or 2 cents goes down to 0. 3 or 4 goes up to 5, 6 or 7 goes down to 5, 8 or 9 goes up to 10, and so on.

Oh duh, of course. But what do you expect from a guy who just now figured out how to look left on a bike!

That makes sense. Hopefully I'll get good at that movement soon!

I do that all the time on both bicycle and motorcycle. It works nice.

I've got mine aligned so I can see the edge of my rear rack, which basically eliminates blind spots. However, when I'm planning to move left to make a turn, I still shoulder check to make sure I haven't missed something before moving over.

Finally watched Amgen ToC stage 1 off the DVR last night, I noticed some of the pros looking back this way, although only when they're coasting in the peloton. When they're trying to break away they always peek back or under their armpit with both hands on the bars.
