Singling-out
Singling-out from a group ride formation of 2-abreast to single file is a tricky manoeuvre, but sometimes has to be done swiftly and efficiently. If not everyone in the group knows how to do it properly, it can be messy, and sometimes a touch of wheels can result in a mass spill just when you least need a mass spill. So here is the hows and whys of singling-out properly.
There are two schools of thought as to which way a 2-abreast group should file out to single file. Some clubs adopt one method, other clubs adopt the other method. Here at iCycle we have adopted the clockwise rotation method. The first method is for the left flank to drop back and each rider on the right flank drops infront of the rider that was previously on their left. The other method is the reverse; i.e. each rider on the left flank accelerates forward slightly, and the rider on the right drops in behind the rider that was previously next to them.
iCycle have adopted the latter method of singling-out as a matter of Club Ride policy for the following reasons. There is only two reasons that a group would want to single-out; 1. there is a car approaching from behind (car-up) and the road is not wide enough for it to pass, and; 2. there is a car approaching from ahead (car-down) and the road is not wide enough for it to pass. Now, the car approaching from behind can wait until the road ahead is clear and straight, as the cyclists have the right to occupy the road until such a time, but for the car approaching from ahead, well, the cyclists have to provide clearance for that car, or a collision is going to happen, and the fastest way to provide that clearance is for the right flank to drop rearwards (away from the approaching car) and slot in "like the teeth of a zip" behind the rider that was previously beside them - a clockwise rotation.
It is important that every rider in the group knows what to do, which direction to go and where to go. This is no time for pleasantries ("you go ahead...", "no please, you go ahead..."). If some riders are singling clockwise and others anticlockwise, this could potentially cause a collision amongst the cyclists and possible with the car.
With a little practice it takes just a few seconds to accomplish. Here are some points to keep in mind.
On main roads, generally, single file is the way to go, especially if there is a solid white line down the middle of the road - otherwise, you are asking motorists to break the law to get around you, even if it is clear and safe for them to do so.
