Whenever I watch team events on the track, I'm amazed and impressed with how close the riders stay to their team mates. I had imagined that fixed gear track bikes allowed better speed control and made this close drafting possible or easier than if they were freewheel bikes. I tested this theory during this ride and only noticed a slight advantage in this regard vs a freewheel bike. It is also possible that this factor is larger than I noticed due to the skill and experience of world class track racers.
