You must be a newbie, so I'll cut you some slack. A 1 mph change in speed can happen when the wind changes speed or direction during your ride, or when you start getting more air resistance because you sat up a little while pedaling and that increased your coefficient of drag. In fact, changes in the wind can easily account for
+3 mph while riding. This is why most serious riders will focus on their cadence and power output instead of just speed.
To take this a step further, the post I was referring to cited a 1 mph difference at 20+ mph. If you are riding above 20 mph, then 1 mph is less than a 5% difference in speed, which is something that is likely not going to be noticed. If you are still a beginner (as I suspect you must be) riding at 12 mph, then sure, that 1 mph matters a lot because it represents a bigger change as a percent of your speed. I recommend you spend more time lurking before posting again, mmkay?
